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” 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.

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 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 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.

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.

SAFETY
Electromagnetic Compatibility (EMC)
Conformance
Products displaying the CE mark are in conformity with European Community Council Directive of 15 Dec
2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility,
2004/108/EC. It was manufactured in conformity with a national standard that implements a harmonized
standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.
It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.
Introduction
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be
transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions
are received by other equipment, electrical interference may result. Electrical emissions may affect many
kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled
machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions
may be required when a welding power source is used in a domestic establishment.
Installation and Use
The user is responsible for installing and using the welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the
welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it
could involve construction of an electromagnetic screen enclosing the power source and the work complete
with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where
they are no longer troublesome.
Note: The welding circuit may or may not be earthed for safety reasons according to national codes.
Changing the earthing arrangements should only be authorized by a person who is competent to access whether the changes will increase the risk of injury, e.g., by allowing parallel
welding current return paths which may damage the earth circuits of other equipment.
Assessment of Area
Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the
welding equipment;
b) radio and television transmitters and receivers;
c) computer and other control equipment;
d) safety critical equipment, e.g., guarding of industrial equipment;
e) the health of the people around, e.g., the use of pacemakers and hearing aids;
f) equipment used for calibration or measurement
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being
used in the environment is compatible. This may require additional protection measures;
h) the time of day that welding or other activities are to be carried out.

AIR VANTAGE® 500 (AU)

SAFETY
Electromagnetic Compatibility (EMC)
The size of the surrounding area to be considered will depend on the structure of the building and other
activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Methods of Reducing Emissions
Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains
supply. Consideration should be given to shielding the supply cable of permanently installed welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The
shielding should be connected to the welding power source so that good electrical contact is maintained
between the conduit and the welding power source enclosure.
Maintenance of the Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations.
All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes
and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and
stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.
Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at
or close to floor level.
Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered.
However, metallic components bonded to the work piece will increase the risk that the operator could
receive a shock by touching these metallic components and the electrode at the same time. The operator
should be insulated from all such bonded metallic components.
Earthing of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size
and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries
where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected
according to national regulations.
Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special
applications1.

position, the

a. When switched from “High” to “Auto” or after
starting the engine, the engine will operate at
full speed for approximately 12 seconds and
then go to low idle speed.
b. When the electrode touches the work or power
is drawn for lights or tools (approximately 100
Watts minimum) the engine accelerates and
operates at full speed.
c. When welding ceases and the AC power load
is turned off, a fixed time delay of approximately 12 seconds starts.
d. If the welding or AC power load is not restarted before the end of the time delay, the idler
reduces the engine speed to low idle speed.
e. The engine will automatically return to high
idle speed when the welding load or AC power
load is reapplied.

When the WELDING TERMINALS switch is in
the “Remotely Controlled” position the idler will
operate as follows:
a. When the triggering device (Amptrol, Arc Start
Switch, etc.) is pressed the engine will accelerate and operate at full speed provided a welding load is applied within approximately 12
seconds.
• If the triggering device remains pressed but no
welding load is applied within approximately 12
seconds the engine may return to low idle
speed.
• If the triggering device is released or welding
ceases the engine will return to low idle speed
after approximately 12 seconds.

WELDING CONTROLS (Items 11
through 20)
11. OUTPUT CONTROL:
The OUTPUT dial is used to preset the output
voltage or current as displayed on the digital
meters for the four welding modes. When in the
CC-STICK or CV-WIRE modes and when a
remote control is connected to the 6-Pin or 14Pin Connector, the auto-sensing circuit automatically switches the OUTPUT CONTROL from control at the welder to the remote control. In the
CV-WIRE mode, when the wire feeder control
cable is connected to the 14-Pin Connector, the
auto-sensing circuit automatically makes OUTPUT CONTROL inactive and the wire feeder voltage control active.
When in the TOUCH START TIG mode and
when a Amptrol is connected to the 6-Pin
Connector, the OUTPUT dial is used to set the
maximum current range of the CURRENT CONTROL of the Amptrol.

12. DIGITAL OUTPUT METERS:
The digital meters allow the output voltage (CVWIRE mode) or current (CC-STICK and TIG
modes) to be set prior to welding using the OUTPUT control knob. During welding, the meters
display the actual output voltage (VOLTS) and
current (AMPS). A memory feature holds the display of both meters on the seven seconds after
welding is stopped. This allows the operator to
read the actual current and voltage just prior to
when welding was ceased. While the display is
being held the left-most decimal point in each
display will be flashing. The accuracy of the
meters is ± 3%.

The ARC CONTROL WIRE/STICK knob is active
in the WIRE and STICK modes, and has different
functions in these modes. This control is not
active in the TIG mode.
CC-STICK mode: In this mode, the ARC CONTROL knob sets the short circuit current (arcforce) during stick welding. Increasing the number from -10(Soft) to +10(Crisp) increases the
short circuit current and prevents sticking of the
electrode to the plate while welding. This can
also increase spatter. It is recommended that the
ARC CONTROL be set to the minimum number
without electrode sticking. Start with a setting at
0.
CV-WIRE mode: In this mode, turning the ARC
CONTROL knob from -10(soft) to +10(crisp)
changes the arc from soft and washed-in to crisp
and narrow. It acts as an inductance/pinch control. The proper setting depends on the procedure and operator preference. Start with a setting
of 0.

15. WELDING TERMINALS SWITCH:

OPERATION

WHAT ARE VRD AND ROCV DEVICES?
VRD’s are gaining popularity as a “must have” safety
accessory especially where welding applications are
being carried out in an environment with a high-risk of
electric shock such as wet areas and hot humid
sweaty conditions.
VRD and ROCV are abbreviations for two different
safety devices used in a welding power source to help
protect the operator from electric shocks.
VRD stands for “Voltage Reduction Device” and
ROCV stands for “Reduced Open Circuit Voltage”.
Both devices are used as an after market addition or
part of the integral design of a machine. VRD and
ROCV reduce the voltage at the welding output terminals when not welding to a no load voltage of less
than 35V for DC welding and for AC welding 35V peak
25VAC RMS, when the resistance of the output circuit
is in the range of 20-200 (ohms). The lower reactivation resistance of the device, the higher the safety
level and also requires that the welding cable connections be kept in good electrical condition.
Having good electrical connections also limits the possibility of other safety issues such as heat-generated
damage, burns and fires.

WELDING POWER SOURCES
Welding power sources generally have an Open
Circuit Voltage (i.e. the voltage at the welding output
terminals when not welding) in the range of 35115VDC. Welding machines for stick welding
(MMAW) and similar constant current (CC mode)
processes supply a higher open circuit voltage
between the electrode and the work when the welding
machine is switched on and ready to commence welding. These welding machines have high open circuit
voltage (typically 60-80V) then when the arc is established and welding current is drawn the voltage drops
to 20-35V.
Consequently, the greatest danger occurs when handling the electrode and the electrode holder between
welding operations, such as when changing electrodes.
Welding machines for MIG (GMAW & FCAW) have a
flat constant voltage (CV) characteristic, generally with
a lower open circuit voltage (30-50V). Also, the current is turned On and Off by a gun trigger, which also
controls the wire feed. Therefore, the welder is not
exposed to open circuit voltage unless the trigger is
turned on and the wire is feeding. Also, electrodes are
not changed as frequently as for stick welding
(MMAW).

b-6

VRD/ROCV’s are more commonly incorporated into
the stick welding mode (CC) of the welding machines
being used in environments with high-risk of electric
shock.

SAFETY
The reduction of the voltage supplies a safer level of
voltage when an arc is not being struck or when an
electrical resistance less than the welder’s body resistance have been detected. All VRD’s are only an aid
to safety, personal protective equipment and safe
working practices must be observed at all times. The
risk of electric shock during welding from a correctly
installed and maintained welding machine is negligible, provided that sensible precautions are taken by
the user and correct safe working procedures are followed. All of the welding output circuit should be considered electrically active (hot) and the welder should
make sure that they do not become a part of that circuit to ground or they could receive a severe electric
shock that could kill. Safe working procedures should
always be followed whether a VRD is fitted or not.

VRD OPERATION INDICATOR
On the front panel of the Air Vantage 500 (AU) are
two indicator lights. A red light when lit indicates voltage greater than >30V and a green light when lit indicates voltage less than <30V.
These lights monitor the OCV at all times. In the CC
mode when the welding arc has stopped the green
light will illuminate indicating that the VRD has
reduced the OCV to less than 30V. During welding the
red light will illuminate indicating that the OCV is
greater than 30V. During welding the red and green
light will flash on and off. This is normal operation as
the welding voltage will produce less than 30V,
depending on the process and type of electrode being
used.
If the red light remains illuminated after welding in the
CC mode, please refer to your local field service shop
for service.

OPERATION
The low voltage safety features of the VRD’s is to
reduce the possibility of electric shock to the operator,
a very slight delay during striking of the electrode may
be experienced.
The high voltage that is available on units without
VRD’s allows them to penetrate and burn through
dirty, painted and heavily mill scale plate. Units fitted
with VRD’s cannot penetrate and are required to register the correct resistance, which switches the safety
device into weld mode.

AIR VANTAGE® 500 (AU)

b-7

OPERATION

Unlike other VRD’s Lincoln uses micro processor control to monitor and establish the arc without the sticking and shorting of the electrode to the job as seen in
many other VRD installations. Due to the requirement
of the resistance in the circuit to be low, for a VRD to
operate, a good metal-to-metal contact must be made
between the metal core of the electrode and the job.
Any damaged connection anywhere in the output circuit may limit the operation of the VRD. This includes
a good connection of the work return clamp and the
job. The work return clamp should be connected close
as practical to where the welding will be performed.
Some electrodes form a cone at the end of the electrode after the welding arc has been broken, particularly iron powder and low hydrogen electrodes.
This cone will need to be broken off in order to have
the metal core of the electrode to make contact.

STARTING TECHNIQUE
The starting technique that has successfully overcome
the problem is the push, twist, and peel technique.
This technique requires the operator to push the electrode into the joint and twist.
The Push and Twist breaks off the cone and allows
the metal electrode to make contact.
The peel and lift of the electrode establishes a controlled start to the welding arc. Normal welding technique for the application is then used.

The engine used to supply power for your welder is a
heavy duty, industrial engine. It is designed and built
for rugged use. It is very normal for any engine to use
small quantities of oil until the break-in is accomplished. Check the oil level twice a day during the
break-in period. In general this takes 50 to 100 hours

The AIR VANTAGE® 500 (AU) is equipped with the
required R.F. bypass circuitry for the connection of
high frequency generating equipment.

DUTY CYCLE
Duty Cycle is the percentage of time the load is being
applied in a 10 minute period. For example a 60% duty
cycle, represents 6 minutes of load and 4 minutes of no
load in a 10 minute period.

STICK WELDING MODE
The AIR VANTAGE® 500 (AU) can be used with a broad
range of DC stick electrodes. The MODE switch provides
two stick welding settings as follows:

CC-STICK MODE
The CC-STICK position of the MODE switch is
designed for horizontal, vertical-up and over head
welding with all types of electrodes, especially low
hydrogen. The OUTPUT CONTROL knob adjusts the
full output range for stick welding.
The ARC CONTROL knob sets the short circuit (arcforce) current during stick welding. Increasing the
number from -10(Soft) to +10(Crisp) increases the
short circuit current and prevents sticking of the electrode to the plate while welding. This can also
increase spatter. It is recommended that the ARC
CONTROL be set to the minimum number without
electrode sticking. Start with the knob set at 0.

The AIR VANTAGE® 500 (AU) and any high frequency generating equipment must be properly grounded.
See the K930-2 TIG Module operating manuals for
complete instructions on installation, operation, and
maintenance.
When using the TIG Module, the OUTPUT control on
the AIR VANTAGE® 500 (AU) is used to set the maximum range of the CURRENT CONTROL on the TIG
Module or an Amptrol if connected to the TIG Module.

AIR VANTAGE® 500 (AU) SETTINGS WHEN
USING THE K930-2 TIG MODULE
• Set the WELD MODE switch to the “Touch Start Tig 20250 Setting”.
• Set the IDLER switch to the “AUTO” position.
• Set the WELDING TERMINALS switch to the “Remotely
Controlled” position. This will keep the solid state contactor
open and provide a “cold” electrode until the triggering
device (Amptrol or Arc Start Switch) is pressed.

TOUCH START TIG MODE
The AIR VANTAGE® 500 (AU) can be used in a wide
variety of DC TIG welding applications.
The TOUCH START TIG setting of the MODE switch
is for DC TIG (Tungsten Inert Gas) welding. To initiate
a weld, the OUTPUT CONTROL knob is first set to
the desired current and the tungsten is touched to the
work. During the time the tungsten is touching the
work there is very little voltage or current and, in general, avoids tungsten contamination. Then, the tungsten is gently lifted off the work in a rocking motion,
which establishes the arc.
To stop the arc, simply lift the TIG torch away from the
work piece. When the arc voltage reaches approximately 30 volts, the arc will go out and the machine
will automatically reset to the touch start current level.
The tungsten may then be retouched to the work
piece to restrike the arc. The arc may also be started
and stopped with an Amptrol or Arc Start Switch.
The ARC CONTROL is not active in the TIG mode.
In general the ‘Touch Start’ feature avoids tungsten
contamination without the use of a Hi-frequency unit.
If the use of a high frequency generator is desired, the
K930-2 TIG Module can be used with the AIR VANTAGE® 500 (AU). The settings are for reference.

Connect a wire feeder to the AIR VANTAGE® 500
(AU) (AU)according to the instructions in INSTALLATION INSTRUCTIONS Section.

For optimal performance when arc gouging, set the
AIR VANTAGE® 500 (AU) “WELD MODE” switch to
the “CC - STICK” position, and the “ARC CONTROL”
to 10.

The AIR VANTAGE® 500 (AU) in the ”CV-WIRE”
position, permits it to be used with a broad range of
flux cored wire (Innershield and Outershield) electrodes and solid wires for MIG welding (gas metal arc
welding). Welding can be finely tuned using the “ARC
CONTROL”. Turning the ARC CONTROL clockwise
from -10(soft) to +10(crisp) changes the arc from soft
and washed-in to crisp and narrow. It acts as an
inductance/pinch control.

Set the “OUTPUT” knob to adjust output current to the
desired level for the gouging electrode being used
according to the ratings in the following Table B.2

OPERATION

PARALLELING

SIMULTANEOUS WELDING AND AUXILIARY POWER LOADS

When paralleling machines in order to combine their
outputs, all units must be operated in the CC-STICK
mode only at the same output settings. To achieve
this, turn the WELD MODE switch to the CC-STICK
position. Operation in other modes may produce erratic outputs, and large output imbalances between the
units.

It must be noted that the above auxiliary power ratings
are with no welding load.
Simultaneous welding and power loads are specified
in table B.4.

AUXILIARY POWER OPERATION
Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings, if no welding current is being drawn.
The auxiliary power of the AIR VANTAGE® 500 consists of two 15Amp 240VAC single phase receptacles.
The auxiliary power receptacles should only be used
with three wire grounded type plugs or approved double insulated tools with two wire plugs.
The current rating of any plug used with the system
must be at least equal to the current capacity of the
associated receptacle.

MAINTENANCE

Service Instructions
Single- and Two-Stage Engine Air Cleaners

Inspect the New Filter for Damage

Remove the Filter

Rotate the
filter while
pulling
straight out.

Unfasten or unlatch the
service cover. Because
the filter fits tightly over the
outlet tube to create the critical seal, there will
be some initial resistance, similar to breaking
the seal on a jar. Gently move the end of the filter
back and forth to break the seal then rotate while
pulling straight out. Avoid knocking the filter
against the housing.

If your air cleaner has a safety filter, replace it every third primary
filter change. Remove the safety filter as you would the primary
filter. Make sure you cover the air cleaner outlet tube to avoid any
unfiltered contaminant dropping into the engine.

Clean Both Surfaces of the Outlet Tube
and Check the Vacuator™ Valve
Use a clean cloth to wipe the filter sealing surface and the inside of
the outlet tube. Contaminant on the sealing surface could hinder an
effective seal and cause leakage. Make sure that all contaminant is
removed before the new filter is inserted. Dirt accidently transferred
to the inside of the outlet tube will reach the engine and cause
wear. Engine manufacturers say that it takes only a few grams of
dirt to "dust" an engine! Be careful not to damage the sealing area
on the tube.

Wipe both sides
of the outlet
tube clean.

Outer edge of the
outlet tube

Inspect the new filter carefully, paying attention to
the inside of the open end, which is the
sealing area. NEVER install a damaged
filter. A new Donaldson radial seal
filter may have a dry lubricant on the
seal to aid installation.

Insert the New Radial Seal Filter Properly
If you're servicing the safety filter, this should be seated into
position before installing the primary filter.
Insert the new filter carefully. Seat
the filter by hand, making certain it is
completely into the air cleaner housing
before securing the cover in place.
The critical sealing area will stretch
slightly, adjust itself and distribute the sealing pressure evenly. To
complete a tight seal, apply pressure by hand at the outer rim of
the filter, not the flexible center. (Avoid pushing on the center of the
urethane end cap.) No cover pressure is required to hold the seal.
NEVER use the service cover to push the filter into place! Using the
cover to push the filter in could cause damage to the housing, cover
fasteners and will void the warranty.
If the service cover hits the filter before it is fully in place, remove
the cover and push the filter (by hand) further into the air cleaner
and try again. The cover should go on with no extra force.
Once the filter is in place, secure the service cover.

Inner edge of the
outlet tube

If your air cleaner is equipped with a Vacuator Valve
Visually check and physically squeeze to make sure the
valve is flexible and not inverted, damaged or plugged.

Caution
NEVER use the service cover to
push the filter into place! Using
the cover to push the filter in could
cause damage to the housing, cover
fasteners and will void the warranty.

Inspect the Old
Filter for Leak Clues
Visually inspect the old filter for any signs
of leaks. A streak of dust on the clean side
of the filter is a telltale sign. Remove any
cause of leaks before installing new filter.

Check Connectors for Tight Fit
Make sure that all mounting bands, clamps, bolts, and connections
in the entire air cleaner system are tight. Check for holes in piping
and repair if needed. Any leaks in your intake piping will send dust
directly to the engine!
