single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
D If ventilation is poor, use an approved air-supplied respirator.
D Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower th e oxygen level causing injury or death. Be sure the breathing air is safe.
D Do not weld in locations near degreasing, cleaning, or spraying op-
erations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and if necessary, while wearing an
air-supplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded.
OM-1581 Page 1
ARC RAYS can burn eyes and skin.
BUILDUP OF GAS can injure or kill.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
D Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes when welding or watching (see ANSI Z49.1
and Z87.1 listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant mate-
rial (leather and wool) and foot protection.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
D Protect yourself and others from flying sparks and hot metal.
D Do not weld where flying sparks can strike flammable material.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
D Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
D Do not use welder to thaw frozen pipes.
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.

1-5.EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Ma g netic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to power-
frequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

1-5.Information sur les champs électromagnétiques
Données sur le soudage électrique et sur les ef fets, pour l ’organisme,
des champs magnétiques basse fréquence
Le courant de soudage, pendant son passage dans les câbles de soudage, causera des champs électromagnétiques. Il y a eu et il y a encore
un certain souci à propos de tels champs. Cependant, après avoir examiné plus de 500 études qui ont été faites pendant une période de
recherche de 17 ans, un comité spécial ruban bleu du National Research Council a conclu: “L’accumulation de preuves, suivant le
jugement du comité, n’a pas démontré que l’exposition aux champs
magnétiques et champs électriques à haute fréquence représente un
risque à la santé humaine”. Toutefois, des études sont toujours en cours
et les preuves continuent à être examinées. En attendant que les conclusions finales de la recherche soient établies, il vous serait
souhaitable de réduire votre exposition aux champs électromagnéti-
ques pendant le soudage ou le coupage.
Afin de réduire les champs électromagnétiques dans l’environnement
de travail, respecter les consignes suivantes :
1Garder les câbles ensembles en les torsadant ou en les
attachant avec du ruban adhésif.
2Mettre tous les câbles du côté opposé de l’opérateur.
3Ne pas courber pas et ne pas entourer pas les câbles autour de
votre corps.
4Garder le poste de soudage et les câbles le plus loin possible de
vous.
5Relier la pince de masse le plus près possible de la zone de
soudure.
Consignes relatives aux stimulateurs cardiaques :
Les personnes qui portent un stimulateur cardiaque doivent avant tout
consulter leur docteur. Si vous êtes déclaré apte par votre docteur, il est
alors recommandé de respecter les consignes ci–dessus.

Section 4- 11).
Pressing gun trigger will not feed wire,
wire is not energized, shielding gas
flows, and Jog switch activates motor .
Feeder feeds wire but remains in run-in
mode after arc initiation.
Feeder feeds wire, but switches from
weld mode to run-in mode while CV
welding with voltage sensing lead
installed.
Shielding gas leak through gas valve in
gun.
Reset circuit breaker CB1 (see Section 5-11).
Route weld cable through current sensing relay (see Section 3-8).
If constant current (CC) welding, be sure PLG5 is in EXT. position on PC1, and voltage sensing lead is
connected (see Section 3-11).
If constant voltage (CV) welding, be sure PLG5 is in INT. position on PC1, and that voltage sensing lead
is not connected (see Section 3-11).
Be sure PLG5 is i n INT. position on PC1. Disconnect voltage sensing clamp from workpiece (see Section
3-11).
