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.

___________________________________________________
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.

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

SAFETY
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” par ts 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.

ARC RAYS can burn.
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 within applicable OSHA PEL and
ACGIH TLV limits 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.

3.j. Also see Items 6.c. and 8.
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 safet y 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 and CUTTING
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.

6.I. Read and follow NFPA 51B “ Standard for Fire Prevention
During Welding, Cutting and Other Hot Work”, available from
NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma
022690-9101.
6.j. Do not use a welding power source for pipe thawing.

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.

iv

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.

The Invertec V160-T cannot be stacked.

WARNING

TILTING
ELECTRIC SHOCK can kill.
• Only qualified personnel should perform this installation.
• Disconnect input power by removing
plug from receptacle before working
inside V160-T. Allow machine to sit for
5 minutes minimum to allow the power capacitors
to discharge before working inside this equipment.
• Insulate yourself from the work and ground.
• Always wear dry insulating gloves.
• Always connect the V160-T to a power supply
grounded according to the National Electrical Code
and local codes.

------------------------------------------------------------

Place the machine directly on a secure, level surface.
The machine may topple over if this procedure is not
followed.

MACHINE GROUNDING AND HIGH FREQUENCY INTERFERENCE PROTECTION
The Capacitor Discharge Circuit used in the high frequency generator can be blamed for many radio, TV
and electronic equipment interference problems.
These problems may be the result of radiated interference. Proper grounding methods can reduce or eliminate radiated interference.
The Invertec V160-T has been field tested under recommended installation conditions. It complies with
FCC allowable limits for radiation.
Radiated interference can develop in the following
four ways:

SELECT SUITAbLE LOCATION
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.

1. Direct interference radiated from the welder.
2. Direct interference radiated from the welding leads.

• Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal.

3. Direct interference radiated from feedback into the
power lines.

• This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when switched
on.

4. Interference from re-radiation of “pickup” by
ungrounded metallic objects.

• Dirt and dust that can be drawn into the machine
should be kept to a minimum.
• Keep the machine dry and do not place it on wet
ground or in puddles.
• Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on “Machine Grounding and High
Frequency Interference Protection” in this manual.
• When operated in ambient temperatures greater
than 40°C, the output duty cycle may be reduced.

INSTALLATION

Keeping these contributing factors in mind, installing
equipment per the following instructions should minimize problems.
1. Keep the welder power supply lines as short as
possible and enclose as much of them as possible
in rigid metallic conduit or equivalent shielding for a
distance of 50ft. (15.2m). Both ends of the conduit
should be connected to a driven ground and the
entire length should be continuous.
2. Keep the work and electrode leads as short as possible and as close together as possible. Lengths
should not exceed 25ft. (7.6m). Tape the leads
together when practical.
3. Be sure the torch and work cable rubber coverings
are free of cuts and cracks that allow high frequency leakage. Cables with high natural rubber content, such as Lincoln Stable-Arc® better resist high
frequency leakage than neoprene and other synthetic rubber insulated cables.

INPUT CONNECTIONS
WARNING
ELECTRIC SHOCK can kill.
• Have a qualified electrician install
and service this equipment.
• Disconnect input power by removing
plug from receptacle before working
inside V160-T. Allow machine to sit for
5 minutes minimum to allow the power capacitors
to discharge before working inside this equipment.
• Do not touch electrically hot parts.
-----------------------------------------------------------------------

GROUND CONNECTION
The frame of the welder must be
grounded. A ground terminal marked
with the symbol is located on the under
panel for this purpose. See your local
and national electrical codes for proper
grounding methods.

4. Keep the torch in good repair and all connections
tight to reduce high frequency leakage.
5. The work terminal must be connected to a ground
within ten feet of the welder, using one of the following methods.
a) A metal underground water pipe in direct contact with the earth for ten feet or more.
b) A 3/4” (19mm) galvanized pipe or a 5/8”
(16mm) solid galvanized iron, steel or copper
rod driven at least eight feet into the ground.
The ground should be securely made and the
grounding cable should be as short as possible
using cable of the same size as the work cable, or
larger. Grounding to the building frame electrical
conduit or a long pipe system can result in re-radiation, effectively making these members radiating
antennas.
6. Keep all panels securely in place.
7. All electrical conductors within 50 ft (15.2m) of the
welder should be enclosed in grounded, rigid metallic conduit or equivalent shielding. Flexible metallic
conduit is generally not suitable.
8. When the welder is enclosed in a metal building,
several earth driven electrical grounds connected
(as in 5 (b) above) around the periphery of the
building are recommended.

CAUTION
The grounding is supplied in the input cord, it is
important that the Supply Receptacle Ground connection is connected.

INSTALLATION

Fuse the input circuit with time delay fuses marked “D”
or delay type1 circuit breakers. Using fuses or circuit
breakers smaller than recommended may result in
“nuisance” shut-offs from welder inrush currents even
if not welding at high currents.

When the ARFU has been activated due to an input
over current condition, the output will be turned off and
the green Power LED will blink indicating an over-current condition. This condition usually occurs when the
unit is operated beyond its rated duty cycle. The unit
will self-restore after a short time and will be ready for
Also called inverse time or thermal/magnetic circuit
normal operation once the green Power LED stops
breakers. These circuit breakers have a delay in tripping
action that decreases as the magnitude of the current blinking and remains on.

The Invertec V160-T is recommended for use on an
individual branch circuit.

NOTE: The ARFU replaces a fuse (F2) that was used
in older V160’s.

WARNING

115V INPUT
The rated output of the V160-T is available when connected to a 30A branch circuit. When connected to a
branch circuit with lower ampacity, lower welding current and duty cycle must be used. An output guide is
provided below. The values are approximate and must
be adjusted downward if the fuse or circuit breaker
trips off. Other loads on the circuit and fuse/circuit
breaker characteristics will affect the available output.
Do not exceed these welding conditions:

OPERATION

REAR CONTROL PANEL
1. Power Switch: Controls the input power to the
machine. Make sure the machine is properly connected to the input supply before turning the
machine on.(See Figure B.1)
2. Fan: The cooling fan will turn ON when the
machine is turned ON and it will continue to run
whenever the output of the machine is ON. If the
output of the machine is OFF for more than five minutes, the fan will turn OFF. This reduces the amount
of dirt that is deposited inside the machine and
reduces power consumption.(See Figure B.1)
Refer to the Output LED section below for more
information about conditions when the output of the
machine is ON.

• Hot Start: This is a temporary increase in the output
current during the start of the stick welding process.
This helps ignite the arc quickly and reliably.
• Arc Force: This is a temporary increase in the output current during normal stick welding. This temporary increase in output current is used to clear
intermittent connections between the electrode and
the weld puddle that occur during normal stick
welding.
• Anti-Sticking: This is a function which decreases
the output current of the machine to a low level
when the operator makes an error and sticks the
electrode to the work piece. This decrease in current allows the operator to remove the electrode
from the electrode holder without creating large
sparks which can damage the electrode holder.

3. Gas Inlet: Connector for the TIG shielding gas. The
gas source must have a pressure regulator and
flow gage installed.(See Figure B.1)
CONTROLS AND SETTINGS (See Figure B.2)
4. Mode Switch: This switch changes the welding
modes of the machine. The V160-T has three welding modes: Stick (SMAW), Lift TIG (GTAW) and
HF TIG (GTAW).
When the mode switch is in the Stick position, the following welding features are enabled:

OPERATION

When the mode switch is in the Lift TIG position, the
stick welding functions are disabled and the machine is
ready for Lift TIG welding. Lift TIG is a method of starting a TIG weld by first pressing the TIG torch electrode
on the work piece in order to create a low current short
circuit. Then, the electrode is lifted from the work piece to
start the TIG arc. After machine output is triggered ON,
with an Arc Start Switch or Foot Amptrol the arc must be
started within 6.5 seconds or output will turn OFF and
trigger sequence must be restarted.
When the mode switch is in the HF TIG position, the stick
welding functions are disabled and the machine is ready
for HF TIG welding. During the HF TIG mode, the TIG
arc is started by HF without pressing the electrode on the
work piece. After triggering output ON, the HF (and output) used for starting the TIG arc will remain ON for 6.5
seconds. If the arc is not started in this time limit, the trigger sequence must be restarted.

Leave the machine on to allow the internal components to
cool. When the indicator turns off, normal operation is
again possible.
8. Remote LED: This indicator will turn ON when a
remote control is connected to the machine via the
remote control connector. Using a remote control will
change the function of the output current control., refer
to the output current control section below. (Note:
When K814 Arc Start Switch is connected to remote
connector, remote LED will remain OFF).
9. Output LED: This indicator turns on when the output
of the machine is on.
• In the stick welding mode, the output of the machine
is automatically turned ON.
• For both of the TIG welding modes, the output of the
machine is turned ON and OFF by an Arc Start
Switch or Hand/Foot Amptrol attached to the Remote
Control Connector. (See #4 - Mode Switch - above for
details on output triggering for TIG arc starting).

5. Trigger Mode Switch: This switch changes between 2step and 4-step trigger sequences. For an explanation of
these trigger sequences refer to the Trigger Mode
Sequences following Controls and Settings.
6. Power LED: This indicator will blink on and off when
the machine is first turned on. After approximately 2
seconds it will stop blinking and remain on to signal
that the machine is ready. The indicator will also blink

10. Output Current Control: This controls the output or
welding current of the machine.

during over current conditions when operating on
115V input.

The function of this control knob is changed if a remote
control is connected. If the Remote LED is ON, this indicates that a remote control is connected and the function of the output current control will be:

7. Thermal LED: This indicator will turn on when the
machine is overheated and the output has been disabled.
This normally occurs when the duty cycle of the machine
has been exceeded.

• Stick Welding Mode: The remote control will adjust
the output current of the machine from 5 to 160A.
The output current control knob on the display panel
is not used.

FIGURE b.2

• TIG Welding Modes: The maximum output current of
the machine is set by the output current control knob.
The remote control then adjusts the output current
from the minimum output (5A) to the value set by the
output current control knob. For example, if the output
current control knob on the machine is set to 100A
then the remote control will adjust the output current
from a minimum of 5A to a maximum of 100A.

OPERATION

12. Postflow Control: In the TIG welding modes, this
control knob will adjust the shielding gas postflow
time from 0.5 to 30 seconds. (The preflow time is
always 0.5 seconds.) In Stick welding mode, this
function is not used.
13. Digital Display: This meter displays the preset welding current before welding and the actual welding
current during welding. Like the output current control, the function of the meter is changed if a remote
control is connected.

After the arc is started the output current will be
increased to the welding current. The time for this
increase or upslope is presettable. The default is 0.5
seconds.
2. Release the Arc Start Switch to stop welding.
The machine will now decrease the output current at
a controlled rate or downslope time, until the
Start/Crater current is reached and the output of the
machine is turned OFF. The downslope time is
adjusted by the Downslope Parameter.

14. Pulsing Mode Switch: In the TIG welding modes,
this switch turns the pulsing function ON and controls
the pulsing frequency range (20Hz or 300Hz). In
Stick welding mode, this function is not used.

After the arc is turned OFF, the gas valve will remain
open to continue the flow of the shielding gas to the
hot electrode and work piece. The duration of this
postflow shielding gas is adjusted by the Postflow
Parameter. This operation is shown in (2 step diagram 1).
2 Step Diagram 1

15. Pulsing LED: This indicator shows the pulsing frequency when pulsing is turned ON. With this indication, the operator can adjust the frequency to the
desired value before welding. (Note: At higher frequencies the LED blinks very fast and seems to be
continuously ON however it is pulsing.) If pulsing is
turned OFF or if the machine is in Stick welding
mode, the indicator will be OFF.
16. Pulsing Frequency Control: When the pulsing function is ON, this control knob will adjust the pulsing
frequency. The pulsing frequency adjustment range is
0.2 - 20Hz or 3 - 300Hz depending on the Pulsing
Mode Switch position.
17. background Current Control: When the pulsing
function is ON, this control knob will adjust the pulsing background current. This is the current during the
low portion of the pulse waveform; it can be adjusted
from 10% to 90% of the welding current.
TRIGGER MODE SEQUENCES
For the V160-T, TIG welding can be done in either the 2step or 4-step mode which is selected with the Trigger
Mode Switch. DIP Switch functions are set by the factory.
For adjustments on DIP Switch settings and functions
see DIP SWITCH FUNCTIONS in this Operations
Section.

Possible variations of this standard sequence is
shown below. It is possible to press and hold the TIG
torch trigger a second time during downslope to
restart. After the trigger is pressed the output current
will increase to the welding current. This operation is
shown in (2 step diagram 2).

2-Step Sequence
Note: 2-Step works with either an Arc Start Switch (for
output triggering only, current control is at machine) or
with a Foot or Hand Amptrol™ (for both remote output
triggering and current control). 2-Step used with Arc Start
Switch is referenced in following sequence.
1. Press and hold the Arc Start Switch to start the
sequence.
The machine will open the gas valve to start the flow of
the shielding gas. After a 0.5 second preflow time to
purge air from the torch hose, the output of the
machine is turned ON. At this time the arc can be started.

OPERATION

4-Step Sequence
Note: 4-Step works with Arc Start Switch only. Amptrol™
type devices will not work properly and should not
be used. The Arc Start Switch's actuator is also
referred to as the "Tig torch trigger" in the following
sequence.
1. Press and hold the Arc Start Switch to start the
sequence. The machine will open the gas valve to
start the flow of the shielding gas. After 0.5 second
preflow time to purge air from the torch hose, the output of the machine is turned ON. At this time the arc
can be started. After the arc is started the output current will be at the Start/Finish current. This condition
can be maintained as long or as short as necessary.

Possible variations of this standard sequence are
shown below. It is possible to press and hold the TIG
torch trigger another time to end the downslope time
and maintain the output current at the Start/Finish current. When the TIG torch trigger is released the output
will turn OFF and postflow will begin. This operation
shown in (4 step diagram 2).

If the Start/Finish current is not necessary, do not hold
the TIG torch trigger as described at the beginning of
this step. Instead, quickly press and release the trigger. In this condition, the machine will automatically
pass from Step 1 to Step 2 when the arc is started.
2. Release the TIG torch trigger to start the main part of
the weld.
The output current will increase to the welding current.
The time for this increase or upslope is presettable.
The default is 0.5 seconds.
3. Press and hold the TIG torch trigger when the main
part of the weld is complete.
The machine will now decrease the output current at a
controlled rate or downslope time, until the Start/Finish
current is reached. The downslope time is adjusted by
the Downslope Parameter. This Start/Finish current
can be maintained as long or as short as necessary.
4. Release the TIG torch trigger.
The output current of the machine will turn OFF and
the gas valve will remain open to continue the flow of
the shielding gas. The duration of this postflow time is
adjusted by the Postflow control knob. This operation
is shown in (4 step diagram 1).

OPERATION

DIP SWITCH FUNCTIONS
The following sections explain the 8 DIP switch functions of the V160. Read and understand the functions
before making any changes because abnormal operation can occur with the wrong settings. The machine
must be turned OFF when the DIP Switches are
changed.

WARNING

DIP Switch 1: Machine Type
This controls the output of the V160-T and some welding waveform functions. It configures the V160-T to
automatically turn OFF depending on the position of
the Welding Mode switch. Refer to DIP Switch 6 for
more information.
DIP Switch 2: Preflow Timer
This controls the preflow timer for TIG welding (used
only on "T" type machines). When the DIP switch is
OFF the preflow time is 0.5 seconds. When it is ON
the preflow time is 0.1 seconds.

start the flow of the shielding gas. After the preflow
time, the output of the machine is turned ON. At
this time the arc is started according to the selected
welding mode (Lift TIG or HF TIG). After the arc is
started the output current will be at the Start/Crater
current. This condition can be maintained as long
or as short as necessary.

OPERATION

DIP Switch 5: Low OCV Enable
This controls the OCV of the machine. When the
DIP switch is OFF the OCV is set to the normal level
as stated in the manuals for the machines. When
the DIP switch is ON the OCV is reduced to 20V.
This low OCV mode was created for the Australian
markets and should only be used as required by
these Australian specifications. The low OCV will
somewhat reduce the starting performance of the
machine when dirt, rust, and/or slag is present on the
work piece.

b-10

• Remote control connected. The TIG slope functions
are disabled for the 2 step trigger mode. If slopes
are needed a foot pedal remote control can be
used. The TIG slope functions are enabled for the 4
step trigger mode.
A trigger is always needed to turn ON the output of
the machine.

DIP Switch 6: European/USA Machine
Configuration
This configures several functions of the V160 as
required by the European and USA markets. For the
European market it is OFF and for the USA market it
is ON.
Specifically, this configures the operation of the TIG
slope timers, remote control, and trigger. However,
this configuration also depends on the position of
DIP Switch 1 which selects the machine type. This
setting can be changed but only if the following functions are clearly understood.
(DIP Switch 1 = OFF)
In TIG welding mode, the following conditions can
exist.
• European Machine Configuration (DIP Switch 6 =
OFF)
The TIG slope functions are always enabled. After
the arc is started the output current will be increased
(upslope) to the welding current. At the end of the
weld the current will be decreased with the downslope function. Using a "foot pedal" remote control is
not recommended with this setup.
A trigger is always needed to turn ON the output of
the machine.
• USA Machine Configuration (DIP Switch 6 = ON)
The TIG slope functions depends on the possible
connection of a remote control.
• No remote control connected. The TIG slope functions are enabled. After the arc is started the output
current will be increased (upslope) to the welding
current. At the end of the weld the current will be
decreased with the downslope function.

2. To adjust the start/crater current, output current
from the machine must flow through a load bank or
a TIG arc. Connect the necessary equipment. In
both cases, load bank or TIG arc, a trigger must be
connected to the machine. If a load bank is used, it
must be setup for 160A and approximately 25V.
3. Make sure all electrical connections are free from
contact with other parts of the machine. Reconnect
the case back if necessary. Turn ON the machine.

Start/Crater Current Adjustment
The start/crater current of a "T" type machine can be
changed if necessary. The values are set from the factory.
European Machines:
20% (160A welding current = 32A start/crater current)
USA Machines:
10% (160A welding current = 16A start/crater current)

WARNING
be sure that all installation, operation, maintenance and repair procedures are performed only
by qualified individuals. Lincoln Electric is not
responsible for damages caused by improper
installation, improper care or abnormal operation.

4. On the control panel of the machine, select the following:
• Mode Switch: LIFT TIG (Do not use HF TIG or
damage to measuring equipment will occur.)
• Trigger Mode: 4 Step
• Pulsing: OFF
• Output Current: Maximum (160A)
5. Activate the trigger of the machine to achieve the
start or crater current portion of the welding
sequence. Refer to the trigger sequences explained
above if more information is needed.
6. In this condition, measure the output current of the
machine and adjust the start/crater current as necessary. The calibration trimmer for the start/crater
current is located on the left side of the machine (as
viewed from the front) on the display board. The
access hole for this trimmer is the higher one on the
display board. (Do not adjust the lower trimmer on
the display board; this is the output current calibration.)
The output current is set to 160A, therefore the
start/crater current calibration will be a percentage
of this 160A setting. Use the following equation for
determining the desired start/crater current calibration:

This adjustment procedure must be performed
only by Lincoln trained service technicians. The
machine will be operating with the cover removed
where it is possible to come in contact with high
voltages. Read all the following instructions
before starting the procedure.
ELECTRIC SHOCK CAN KILL:
• Welding equipment generates high
voltages.
• Do not touch the live parts of the
machine, the electrode, the work
clamp, or connected work pieces
when this equipment is on.
• Insulate yourself from live electrical connections, the electrode, the work clamp, and the
connected work pieces.
-----------------------------------------------------------------------

Desired start/crater current percentage multiplied
by 160 = calibration current.
For example, to calibrate the machine for 15%
start/crater current, multiply this by 160 to get the
calibration current ( 0.15 x 160 = 24).
7. Release the trigger to turn off the output of the
machine. Turn OFF the machine and disconnect it
from the input source. Reassemble the machine
making sure the ground wire to the cover is connected.

1. Remove the cover of the machine to access the
control Printed Circuit Boards on the case front.
