BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE
powered equipment.

1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
____________________________________________________
1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.

____________________________________________________
1.c. Do not add the fuel near an open flame
welding arc or when the engine is running.
Stop the engine and allow it to cool before
refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and
igniting. Do not spill fuel when filling tank. If
fuel is spilled, wipe it up and do not start
engine until fumes have been eliminated.
____________________________________________________
1.d. Keep all equipment safety guards, covers and devices in
position and in good repair.Keep hands, hair, clothing and
tools away from V-belts, gears, fans and all other moving
parts when starting, operating or repairing equipment.
____________________________________________________
1.e. In some cases it may be necessary to remove safety
guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete.
Always use the greatest care when working near moving
parts.
___________________________________________________
1.f. Do not put your hands near the engine fan.
Do not attempt to override the governor or
idler by pushing on the throttle control rods
while the engine is running.

ELECTRIC AND
MAGNETIC FIELDS
may be dangerous
2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.

___________________________________________________
1.g. To prevent accidentally starting gasoline engines while
turning the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.

2.d.5. Do not work next to welding power source.

SAFETY
ARC RAYS can burn.

ELECTRIC SHOCK can
kill.
3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
skin or wet clothing. Wear dry, hole-free
gloves to insulate hands.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
3.j. Also see Items 6.c. and 8.

4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.

FUMES AND GASES
can be dangerous.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep
your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
5. b. The operation of welding fume control equipment is affected
by various factors including proper use and positioning of
the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker
exposure level should be checked upon installation and
periodically thereafter to be certain it is within applicable
OSHA PEL and ACGIH TLV limits.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other irritating products.
5.d. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
5.f. Also see item 1.b.

SAFETY
WELDING SPARKS can
cause fire or explosion.
6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
the welding sparks from starting a fire.
Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even though they have
been “cleaned”. For information, purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
6.h. Also see item 1.c.

CYLINDER may explode
if damaged.
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
7.c. Cylinders should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.
7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.

FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.

SAFETY
PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suivantes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de n’importe quelle partie
du corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou
quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
l’électricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

INSTALLATION

SAFETY PRECAUTIONS Read this
entire installation section before you start installation.
WARNING

LIFTING
Lift the machine by the lift bail only. The lift bail is
designed to lift the power source only. Do not attempt
to lift the Power Wave with accessories attached to it.

STACKING

ELECTRIC SHOCK can kill.
• Only qualified personnel should perform this installation.
• Turn the input power OFF at the
disconnect switch or fuse box before
working on this equipment. Turn off the input
power to any other equipment connected to the
welding system at the disconnect switch or fuse
box before working on the equipment.
• Do not touch electrically hot parts.

Power Wave machines can be stacked to a maximum
of 3 high.

CAUTION
The bottom machine must always be placed on a
firm, secure, level surface. There is a danger of
machines toppling over if this precaution is not
taken.

MACHINE GROUNDING

• Always connect the Power Wave grounding lug
(located inside the reconnect input access door)
to a proper safety (Earth) ground.
----------------------------------------------------------

SELECT SUITABLE LOCATION
Do not use Power Waves in outdoor environments.
The Power Wave power source should not be subjected to falling water, nor should any parts of it be submerged in water. Doing so may cause improper operation as well as pose a safety hazard. The best practice is to keep the machine in a dry, sheltered area.
Do not mount the Power Wave 455M over combustible surfaces. Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate
at least .060" (1.6mm) thick, which shall extend not
less than 5.90" (150mm) beyond the equipment on all
sides.
Place the welder where clean cooling air can freely circulate in through the rear louvers and out through the
case sides and bottom. Dirt, dust, or any foreign material that can be drawn into the welder should be kept at
a minimum. Do not use air filters on the air intake
because the air flow will be restricted. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdowns.
Machines are equipped with F.A.N. (fan as needed)
circuitry. The fan runs whenever the output is enabled,
whether under loaded or open circuit conditions. The
fan also runs for a period of time (approximately 5 minutes) after the output is disabled, to ensure all components are properly cooled.
If desired, the F.A.N. feature can be disabled (causing the
fan to run whenever the power source is on). To disable
F.A.N., connect leads 444 and X3A together at the output
of the solid state fan control relay, located on the back of
the Control PC board enclosure. (See Wiring Diagram)

The frame of the welder must be grounded. A ground
terminal marked with the symbol
is located inside
the reconnect/input access door for this purpose. See
your local and national electrical codes for proper
grounding methods.

HIGH FREQUENCY PROTECTION
Locate the Power Wave away from radio controlled
machinery.

CAUTION
The normal operation of the Power Wave may
adversely affect the operation of RF controlled
equipment, which may result in bodily injury or
damage to the equipment.

INPUT CONNECTION
WARNING
Only a qualified electrician should
connect the input leads to the Power
Wave. Connections should be made
in accordance with all local and
national electrical codes and the
connection diagram located on the
inside of the reconnect/input access door of the
machine. Failure to do so may result in bodily
injury or death.
------------------------------------------------------------Use a three-phase supply line. A 1.75 inch (45 mm)
diameter access hole for the input supply is located on
the upper left case back next to the input access door.
Connect L1, L2, L3 and ground according to the Input
Supply Connection Diagram decal located on the
inside of the input access door or refer to Figure A.1

FIGURE A.1 - CONNECTION DIAGRAM ON CONNECTION/INPUT ACCESS DOOR

NOTE: Turn main input power to the machine OFF before performing connection procedure. Failure to
do so will result in damage to the machine.

INPUT FUSE AND SUPPLY WIRE
CONSIDERATIONS
Refer to the Technical Specifications at the beginning
of this Installation section for recommended fuse and
wire sizes. Fuse the input circuit with the recommended super lag fuse or delay type breakers (also called
“inverse time” or “thermal/magnetic” circuit breakers).
Choose an input and grounding wire size according to
local or national electrical codes. Using fuses or circuit
breakers smaller than recommended may result in
“nuisance” shut-offs from welder inrush currents, even
if the machine is not being used at high currents.

INPUT VOLTAGE CHANGE OVER (FOR
MULTIPLE
INPUT
VOLTAGE
MACHINES ONLY)
Welders are shipped connected for the highest input
voltage listed on the rating plate. To move this connection to a different input voltage, see the diagram
located on the inside of the input access door. If the
main reconnect switch or link position is placed in the
wrong position, the welder will not produce output
power.
If the Auxiliary (A) lead is placed in the wrong position,
there are two possible results. If the lead is placed in a
position higher than the applied line voltage, the
welder may not come on at all. If the Auxiliary (A) lead
is placed in a position lower than the applied line voltage, the welder will not come on, and the two circuit
breakers or fuses in the reconnect area will open. If
this occurs, turn off the input voltage, properly connect
the (A) lead, reset the breakers, and try again. For
machines equipped with a fuse in the reconnect area,
turn off the input voltage and replace the fuse with the
spare fuse that is attached to the reconnect switch pin.

ELECTRODE AND WORK CABLE
CONNECTIONS
Connect a work lead of sufficient size and length (Per
Table 1) between the proper output terminal on the
power source and the work. Be sure the connection to
the work makes tight metal-to-metal electrical contact.
To avoid interference problems with other equipment
and to achieve the best possible operation, route all
cables directly to the work and wire feeder. Avoid
excessive lengths and do not coil excess cable.
Minimum work and electrode cable sizes are as follows:
TABLE A.1
(Current (60% Duty Cycle)
MINIMUM COPPER
WORK CABLE SIZE AWG
Up To-100 Ft. Length (30 m)
400 Amps
2/0 (67 mm2)
500 Amps
3/0 (85 mm2)
600 Amps
3/0 (85 mm2)
NOTE: K1796 coaxial welding cable is recommended
to reduce the cable inductance in long cable lengths.
This is especially important when Pulse welding up to
350 amps.

CAUTION
When using inverter type power sources like the
Power Waves, use the largest welding (electrode
and work) cables that are practical. At least 2/0 (67
mm2) copper wire - even if the average output current would not normally require it. When pulsing,
the pulse current can reach very high levels.
Voltage drops can become excessive, leading to
poor welding characteristics, if undersized welding cables are used.
------------------------------------------------------------------------

POWER WAVE 455M

INSTALLATION

CABLE INDUCTANCE, AND ITS EFFECTS
ON PULSE WELDING
For Pulse Welding processes, cable inductance will
cause the welding performance to degrade. For the
total welding loop length less than 50 ft.(15.24m), traditional welding cables may be used without any effects
on welding performance. For the total welding loop
length greater than 50 ft.(15.24m)), the K1796 Coaxial
Welding Cables are recommended. The welding loop
length is defined as the total of electrode cable length
(A) + work cable length (B) + work length (C) (See
Figure A.3).

CAUTION
Excessive voltage drops caused by poor work
piece connections often result in unsatisfactory
welding performance.
------------------------------------------------------------------------

NEGATIVE ELECTRODE POLARITY
When negative electrode polarity is required, such as
in some Innershield applications, switch the output
connections at the power source (electrode cable to
the negative (-) stud, and work cable to the positive (+)
stud).

FIGURE A.3

For long work piece lengths, a sliding ground should
be considered to keep the total welding loop length
less than 50 ft.(15.24m). (See Figure A.4.)

When operating with electrode polarity negative the
"Electrode Sense Polarity" DIP switch must be set to
the "Negative" position on the Wire Drive Feed Head
PC Board. The default setting of the switch is positive
electrode polarity. Consult the Power Feed instruction
manual for further details.

MEASURE FROM END
OF OUTER JACKET OF
CABLE

Output connections on some Power Waves are made
via 1/2-13 threaded output studs located beneath the
spring loaded output cover at the bottom of the case
front.
Most welding applications run with the electrode being
positive (+). For those applications, connect the electrode cable between the wire feeder and the positive
(+) output stud on the power source (located beneath
the spring loaded output cover near the bottom of the
case front). Connect the other end of the electrode
cable to the wire drive feed plate. The electrode cable
lug must be against the feed plate. Be sure the connection to the feed plate makes tight metal-to-metal
electrical contact. The electrode cable should be sized
according to the specifications given in the work cable
connections section. Connect a work lead from the
negative (-) power source output stud to the work
piece. The work piece connection must be firm and
secure, especially if pulse welding is planned.

The best arc performance occurs when the Power
Waves have accurate data about the arc conditions.
Depending upon the process, inductance within the
electrode and work lead cables can influence the
apparent voltage at the studs of the welder. Voltage
sense leads improve the accuracy of the arc conditions
and can have a dramatic effect on performance.
Sense Lead Kits (K940-10, -25 or -50) are available for
this purpose.

CAUTION
If the voltage sensing is enabled but the sense
leads are missing, improperly connected, or if the
electrode polarity switch is improperly configured,
extremely high welding outputs may occur.
-----------------------------------------------------------------------The ELECTRODE sense lead (67) is built into the control cable, and is automatically enabled for all semiautomatic processes. The WORK sense lead (21) connects to the Power Wave at the four pin connector
located underneath the output stud cover. By default
the WORK voltage is monitored at the output stud in
the Power Wave 455M. For more information on the
WORK sense lead (21), see "Work Voltage Sensing”
in the following paragraph.
All constant current processes sense the voltage at the
output studs of the POWER WAVE-455M by default.

POWER WAVE TO SEMI-AUTOMATIC POWER FEED WIRE FEEDER
INTERCONNECTIONS

For processes requiring work voltage sensing, connect the (21) work voltage sense lead (K940) from the
Power Wave work sense lead receptacle to the work
piece. Attach the sense lead to the work piece as
close to the weld as practical, but not in the return current path. Enable the work voltage sensing in the
Power Wave as follows:

WARNING
• Do not touch electrically live
parts or electrodes with your
skin or wet clothing.
• Insulate yourself from the work
and ground.
• Always wear dry insulating gloves.
-----------------------------------------------------------

The Power Wave 455M and semi-automatic POWER
FEED family communicate via a 5 conductor control
cable (K1543). The control cable consists of two power
leads, one twisted pair for digital communication, and
one lead for voltage sensing. The cables are designed to
be connected end to end for ease of extension. The output receptacle on the Power Wave 455M is located
beneath the spring loaded output cover at the bottom of
the case front. The input receptacle on the Power Feed
is typically located at the back of the feeder, or on the
bottom of the user interface.
For convenience sake, the electrode and control cables
can be routed behind the left or right strain reliefs (under
the spring loaded output cover), and along the channels
formed into the base of the Power Wave, out the back of
the channels, and then to the wire feeder.

1. Turn off power to the power source at the disconnect switch.

Due to the flexibility of the platform the configuration may
vary. The following is a general description of the system.

2. Remove the front cover from the power source.

SYSTEM DESCRIPTION

1

The Power Wave 455M and Power Feed M family of
products utilize a digital communication system called
ArcLink. Simply put, ArcLink allows large amounts of
information to be passed at very high speeds between
components (nodes) in the system. The system requires
only two wires for communication, and because of its
bus-like structure, the components may be connected to
the network in any order, thus simplifying the system setup.

4. Using a pencil or other small object,
slide the switch right to the OFF position if the work sense lead is NOT connected. Conversely, slide the switch to
the ON position if the work sense lead
is present.

3. The control board is on the left side of
the power source. Locate the 8-position
DIP switch and look for switch 8 of the
DIP switch.

5. Replace the cover and screws. The PC board will
“read” the switch at power up, and configure the
work voltage sense lead appropriately.

Each "system" must contain only one power source.
The number of wire feeders is determined by the type
of wire feeder. Refer to the wire feeder instruction
manual for details

INSTALLATION

CONFIGURING THE SYSTEM
For codes below 11100, consult the semi-automatic
Power Feed instruction manual for configuration information about DIP switch settings.
For codes above 11100, the power source will “Auto
Map” the system eliminating most of the need to set
DIP switches to configure the system.

If a system can not be “Auto Mapped” then the status
light on the power source will blink green fast and the
welder output will be disabled. If a system is not
“Auto-mappable”, then consult the instruction manual
for the accessory being used for configuration information about DIP switch settings, or consult your local
Lincoln sales representative.

WELDING WITH MULTIPLE POWER
WAVES
CAUTION
Special care must be taken when more than one
Power Wave is welding simultaneously on a single
part. Arc blow and arc interference may occur or
be magnified.
-----------------------------------------------------------------------Each power source requires a work lead from the
work stud to the welding fixture. Do not combine all of
the work leads into one lead. The welding travel directions should be in the direction moving away from the
work lead as shown below. Connect all of the work
sense leads from each power source to the work
piece at the end of the weld.

CONTROL CABLE SPECIFICATIONS
It is recommended that genuine Lincoln control cables
be used at all times. Lincoln cables are specifically
designed for the communication and power needs of
the Power Wave / Power Feed system.

CAUTION
The use of non-standard cables, especially in
lengths greater than 25 ft.(7.62), can lead to communication problems (system shutdowns), poor
motor acceleration (poor arc starting) and low
wire driving force (wire feeding problems).
-----------------------------------------------------------------------The K1543 series of control cables can be connected
end to end for ease of extension. Do not exceed more
than 100 feet (30.5 m) total control cable length.

For the best results when pulse welding, set the wire
size and wire feed speed the same for all the Power
Waves. When these parameters are identical, the
pulsing frequency will be the same, helping to stabilize
the arcs.
Every welding gun requires a separate shielding gas
regulator for proper flow rate and shielding gas coverage.
Do not attempt to supply shielding gas for two or more
guns from only one regulator.
If an anti-spatter system is in use then each gun must
have its own anti-spatter system. (See Figure A.2)

DIP SWITCH SETTINGS AND LOCATIONS
DIP switches on the P.C. Boards allow for custom
configuration of the Power Wave. To access the DIP
switches:
• Turn off power at the disconnect switch.
• Remove the top four screws securing the front
access panel.
• Loosen, but do not completely remove, the bottom
two screws holding the access panel.
• Open the access panel, allowing the weight of the
panel to be carried by the bottom two screws. Make
sure to prevent the weight of the access panel from
hanging on the harness.
• Adjust the DIP switches as necessary.
• Replace the panel and screws, and restore power.

WATER FLOW SENSOR
Water cooled guns can be damaged very quickly if
they are used even momentarily without water flowing.
A water flow sensor is recommended for those water
coolers that do not have an integral flow sensor.
Recommended practice is to install a water flow sensor such as K1536-1 on the water return line of the
torch. When fully integrated into the welding system,
the sensor will prevent welding if no water flow is present.

OPERATION

GENERAL DESCRIPTION
The Power Wave semi-automatic power source is
designed to be a part of a modular, multi-process
welding system. Depending on configuration, it can
support constant current, constant voltage, and pulse
welding modes.
The Power Wave power source is designed to be
used with the semi automatic family of Power Feed
wire feeders, operating as a system. Each component
in the system has special circuitry to "talk with" the
other system components, so each component (power
source, wire feeder, user interface) knows what the
other is doing at all times. These components communicate with ArcLink
The Power Wave 455M is a high performance, digitally controlled inverter welding power source capable of
complex, high-speed waveform control. Properly
equipped, it can support the GMAW, GMAW-P,
FCAW, SMAW, GTAW, and CAC processes. It carries
an output rating of either 450 amps, 38 volts; or 400
amps, 36 volts (both at 100% duty cycle), depending
on input voltage and frequency.

RECOMMENDED PROCESSES AND
EQUIPMENT
RECOMMENDED PROCESSES
The Power Wave 455M can be set up in a number of
configurations, some requiring optional equipment or
welding programs. Each machine is factory preprogrammed with multiple welding procedures, typically
including GMAW, GMAW-P, FCAW, GTAW, and CAC
for a variety of materials, including mild steel, stainless steel, cored wires, and aluminum.
The Power Wave 455M is recommended for semiautomatic welding with ArcLink compatible equipment
like the Power Feed M series of feeders. The Power
Wave 455M can have a number of modules installed
that allow the machine to be used in Robotic and hard
automation applications.
Wire Drive Interface Module
For Robotic platforms the Wire Drive Control Module
is required to drive the PF-10R wire drive. This module can be factory installed on K2202-3 or field
installed for robotic applications.
The Wire Drive Control Module is also be equipped
with a terminal strip for making simple input signal
connections. It can be used to externally control the
basic wire drive function. It is divided into three
groups: Trigger group, Cold Inch group, and
Shutdown group.

DeviceNet Interface Module
This module can be used for DeviceNet capability. It
will has a 5 pin sealed mini connector per ANSI
B93.55M-1981.
EtherNet/DeviceNet Module
This module includes the DeviceNet and EtherNet
capability. The DeviceNet uses a 5 pin sealed mini
connector per ANSI B93.55M-1981. The EtherNet
uses a RJ5 connector.

RECOMMENDED EQUIPMENT
Power Wave 455M – Semi-Automatic Operation
Semi Automatic Power Waves can only be used with
ArcLink compatible Power Feed semi-automatic wire
feeders and modules. In addition, the Power Feed
semi-automatic wire feeders may require optional
equipment to access certain weld modes in the Power
Wave. Other models of Lincoln feeders, or any models of non-Lincoln wire feeders, cannot be used.
All welding programs and procedures are selected
through the Power Feed M semi-automatic user interface

REQUIRED EQUIPMENT
Any ArcLink compatible semi-automatic wire feeding
equipment. Specifically, the semi-automatic Power
Feed M family.

LIMITATIONS
WARNING
• The Power Waves are not to be used in outdoor
environments.
-----------------------------------------------------------------------• Only ArcLink compatible Power Feed semi-automatic wire feeders and users interfaces may be used.
Other Lincoln wire feeders or non-Lincoln wire feeders cannot be used.
• Power Wave 455M Output Limitations
The Power Wave 455M will support maximum average output current of 570 Amps (@ 60% duty cycle)
on the standard Power Wave stud.

DUTY CYCLE AND TIME PERIOD
The Power Feed wire feeders are capable of welding
at a 100% duty cycle (continuous welding). The power
source will be the limiting factor in determining system
duty cycle capability. Note that the duty cycle is based
upon a ten minute period. A 60% duty cycle represents 6 minutes of welding and 4 minutes of idling in a
ten minute period.

NOMINAL PROCEDURES

WELDING ADJUSTMENTS

The Power Wave is designed to operate with 3/4"
electrode stick-out for CV and Pulse processes.

All adjustments are made on the system component
known as the User Interface (Control Box), which contains the switches, knobs, and digital displays necessary to control both the Power Wave and a Power
Feed wire feeder. Typically, the Control Box is supplied as part of the wire feeder. It can be mounted
directly on the wire feeder itself, the front of the power
source, or mounted separately, as might be done in a
welding boom installation.

FRINGE PROCEDURES
Excessively short or long electrode stick-outs may
function only on a limited basis, if at all.

MAKING A WELD

WARNING
The serviceability of a product or structure utilizing the welding programs is and must be the sole
responsibility of the builder/user. Many variables
beyond the control of The Lincoln Electric
Company affect the results obtained in applying
these programs. These variables include, but are
not limited to, welding procedure, plate chemistry
and temperature, weldment design, fabrication
methods and service requirements. The available
range of a welding program may not be suitable
for all applications, and the build/user is and must
be solely responsible for welding program selection.
-----------------------------------------------------------------------The steps for operating the Power Wave will vary
depending upon the options installed in the user interface (control box) of the welding system. The flexibility
of the Power Wave system lets the user customize
operation for the best performance.
First, consider the desired welding process and the
part to be welded. Choose an electrode material,
diameter, shielding gas and process (GMAW, GMAWP, etc.)
Second, find the program in the welding software that
best matches the desired welding process. The standard software shipped with the Power Waves encompasses a wide range of common processes and will
meet most needs. If a special welding program is
desired, contact the local Lincoln Electric sales representative.

Because the Control Box can be configured with many
different options, your system may not have all of the
following adjustments. Regardless of availability, all
controls are described below. For further information,
consult the Power Feed wire feeder instruction manual.
• WFS / AMPS:
In synergic welding modes (synergic CV, pulse
GMAW) WFS (wire feed speed) is the dominant control parameter, controlling all other variables. The user
adjusts WFS according to factors such as weld size,
penetration requirements, heat input, etc. The Power
Wave then uses the WFS setting to adjust its output
characteristics (output voltage, output current) according to pre-programmed settings contained in the
Power Wave 455M. In non-synergic modes, the WFS
control behaves more like a conventional CV power
source where WFS and voltage are independent
adjustments. Therefore to maintain the arc characteristics, the operator must adjust the voltage to compensate for any changes made to the WFS.
In constant current modes (stick, TIG) this control
adjusts the output current, in amps.
• VOLTS / TRIM:
In constant voltage modes (synergic CV, standard
CV) the control adjusts the welding voltage.
In pulse synergic welding modes (pulse GMAW only)
the user can change the Trim setting to adjust the arc
length. It is adjustable from 0.500 to 1.500. A Trim setting of 1.000 is a good starting point for most conditions.

To make a weld, the Power Wave needs to know the
desired welding parameters. The Power Feed (PF)
family of feeders communicate settings to the Power
Wave through control cable connection. Arc length,
wire feed speed, arc control, etc. are all communicated digitally via the control cable.

OPERATION

• WELDING MODE
May be selected by name (CV/MIG, CC/Stick Crisp,
Gouge, etc.) or by a mode number (10, 24, 71, etc.)
depending on the Control Box options. Selecting a
welding mode determines the output characteristics of
the Power Wave power source. For a more complete
description of the welding modes available in the
Power Wave, see the explanation below.

Non Synergic CV:
This type of CV mode behaves more like a conventional CV power source. Voltage and WFS are independent adjustments. Therefore to maintain the arc
characteristics, the operator must adjust the voltage to
compensate for any changes made to the WFS.

• ARC CONTROL
Also known as Inductance or Wave Control. Allows
operator to vary the arc characteristics from "soft" to
"harsh" in all weld modes. It is adjustable from -10.0 to
+10.0, with a nominal setting of 00.0 (The nominal setting of 00.0 may be displayed as OFF on some Power
Feed wire feeder control panels). See the Welding
Mode descriptions, below, for detailed explanations of
how the Arc Control affects each mode.

All CV Modes:
Arc Control, often referred to as wave control, adjusts
the inductance of the wave shape. The wave control
adjustment is similar to the "pinch" function in that it is
inversely proportional to inductance. Therefore,
increasing wave control greater than 0.0 results in a
harsher, colder arc while decreasing the wave control
to less than 0.0 provides a softer, hotter arc.
(See Figure A.5)

CONSTANT VOLTAGE WELDING
Synergic CV:
For each wire feed speed, a corresponding voltage is
preprogrammed into the machine through special software at the factory. The nominal preprogrammed voltage is the best average voltage for a given wire feed
speed, but may be adjusted to preference. When the
wire feed speed changes, the Power Wave automatically adjusts the voltage level correspondingly to
maintain similar arc characteristics throughout the
WFS range.

OPERATION

PULSE WELDING
Pulse welding procedures are set by controlling an
overall "arc length" variable. When pulse welding, the
arc voltage is highly dependent upon the waveform.
The peak current, back ground current, rise time, fall
time and pulse frequency all affect the voltage. The
exact voltage for a given wire feed speed can only be
predicted when all the pulsing waveform parameters
are known. Using a preset voltage becomes impractical, and instead the arc length is set by adjusting
"trim".
Trim adjusts the arc length and ranges from 0.50 to
1.50, with a nominal value of 1.00. Trim values greater
than 1.00 increase the arc length, while values less
than 1.00 decrease the arc length.
Most pulse welding programs are synergic. As the
wire feed speed is adjusted, the Power Wave will
automatically recalculate the waveform parameters to
maintain similar arc properties.

B-8

The Power Wave utilizes "adaptive control" to compensate for changes in electrical stick-out while welding. (Electrical stick-out is the distance from the contact tip to the work piece.) The Power Wave waveforms are optimized for a 0.75" (19mm) stick-out. The
adaptive behavior supports a range of stickouts from
0.50" (13mm) to 1.25" (32mm). At very low or high
wire feed speeds, the adaptive range may be less due
to reaching physical limitations of the welding process.
Arc Control, often referred to as wave control, in pulse
programs usually adjusts the focus or shape of the
arc. Wave control values greater than 0.0 increase the
pulse frequency while decreasing the background current, resulting in a tight, stiff arc best for high speed
sheet metal welding. Wave control values less than
0.0 decrease the pulse frequency while increasing the
background current, for a soft arc good for out-of-position welding.

MAINTENANCE
SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Only Qualified personnel should
perform this maintenance.
• Turn the input power OFF at the
disconnect switch or fuse box
before working on this equipment.
•

Do not touch electrically hot parts.

ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing
out the machine, using a low pressure airstream, to
remove accumulated dust and dirt from the intake and
outlet louvers, and the cooling channels in the
machine.

PERIODIC MAINTENANCE
Calibration of the Power Wave 455M is critical to its
operation. Generally speaking the calibration will not
need adjustment. However, neglected or improperly
calibrated machines may not yield satisfactory weld
performance. To ensure optimal performance, the calibration of output Voltage and Current should be
checked yearly.

CALIBRATION SPECIFICATION
Output Voltage and Current are calibrated at the factory. Generally speaking the machine calibration will not
need adjustment. However, if the weld performance
changes, or the yearly calibration check reveals a
problem, contact the Lincoln Electric Company for the
calibration software utility.

The calibration procedure itself requires the use of a
grid, and certified actual meters for voltage and current. The accuracy of the calibration will be directly
affected by the accuracy of the measuring equipment
you use. Detailed instructions are available with the
utility.

TROUBLESHOOTING

USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
The Power Wave / Power Feed are best diagnosed as
a system. Each component (power source, user interface, and feed head) has a status light, and when a
problem occurs it is important to note the condition of
each. In addition, errors displayed on the user interface in most cases indicate only that a problem exists
in the power source, not what the problem may be.
Therefore, prior to cycling power to the system,
check the power source status light for error
sequences as noted below. This is especially
important if the user interface displays "Err 006"
or "Err 100" .

charts for both machine and weld performance.
The STATUS LIGHT is a two color light that indicates
system errors. Normal operation is a steady green
light. Error conditions are indicated in the following
chart.
NOTE: The Power Wave 455M status light will flash
green, and sometimes red and green, for up to one
minute when the machine is first turned on. This is a
normal situation as the machine goes through a self
test at power up.

Included in this section is information about the power
source Status LED, and some basic troubleshooting
LIGHT CONDITION
Status LED is solid green (no blinking).

MEANING
1. System OK. Power source communicating normally
with wire feeder and its components.

Status LED is blinking green.

2. Occurs during a reset, and indicates the Power
Wave 455M is mapping (identifying) each component in the system. Normal for first 1-10 seconds
after power is turned on, or if the system configuration is changed during operation.

Status LED is blinking red and green.

3. Non-recoverable system fault. If the PS Status light
is flashing any combination of red and green, errors
are present in the Power Wave 455M. Read the
error code before the machine is turned off.
Error Code interpretation through the Status light is
detailed in the Service Manual. Individual code digits
are flashed in red with a long pause between digits. If
more than one code is present, the codes will be
separated by a green light.
To clear the error, turn power source off, and back
on to reset.

Status LED is solid red (no blinking).

Non recoverable hardware fault. Generally indicates
nothing is connected to the Power Wave 455M wire
feeder receptacle. See Trouble Shooting Section.

Status LED is blinking red.

When accompanied by an under voltage error on the same side, it
indicates no capacitor voltage present on that side, and is usually
the result of an open or short in the primary side of the machine.

Thermal error

Indicates over temperature. Usually accompanied by Thermal LED.
Check fan operation. Be sure process does not exceed duty cycle
limit of the machine.

Soft start error

Secondary overcurrent error

Capacitor precharge failed. Usually accompanied by codes 32-35.
The secondary (weld) current limit has been exceeded. When this
occurs the machine output will phase back to 100 amps, typically
resulting in a condition referred to as "noodle welding"
NOTE: The secondary limit is 570 amps for the standard stud, and
325 amps for all single phase operation.

Capacitor delta error

The maximum voltage difference between the main capacitors has
been exceeded. May be accompanied by errors 32-35.

Single phase error

Indicates machine is running on single phase input power. Usually
caused by the loss of the middle leg (L2).
Error codes that contain three or four digits are defined as fatal
errors. These codes generally indicate internal errors on the PS
Control Board. If cycling the input power on the machine does not
clear the error, try reloading the operating system. If this fails,
replace the control board.
