Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is on.
The input power circuit and machine internal
circuits are also live when power is on. In semiautomatic or
automatic wire welding, the wire, wire reel, drive roll housing, and all
metal parts touching the welding wire are electrically live. Incorrectly
installed or improperly grounded equipment is a hazard.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the
work or ground.
Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on
unit.
Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according
to OSHA 29 CFR 1910.147 (see Safety Standards).
Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
Always verify the supply ground − check and be sure that input
power cord ground wire is properly connected to ground terminal
in disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
When making input connections, attach proper grounding
conductor first − double-check connections.
Frequently inspect input power cord for damage or bare wiring −
replace cord immediately if damaged − bare wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
This group of symbols means Warning! Watch Out! possible
ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary
actions to avoid the hazards.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
Do not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after stopping
engine on inverters.
Stop engine on inverter and discharge input capacitors according
to instructions in Maintenance Section before touching any parts.
ARC RAYS can burn eyes and skin.
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.
Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes from arc rays and sparks when welding or
watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).
Wear approved safety glasses with side shields under your
helmet.
Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
If ventilation is poor, use an approved air-supplied respirator.
Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
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 the oxygen level causing injury or death. Be sure the
breathing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
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.

WELDING can cause fire or explosion.
HOT PARTS can cause severe burns.
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 workpiece, and hot equipment can cause fires
and 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.
Protect yourself and others from flying sparks and hot metal.
Do not weld where flying sparks can strike flammable material.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
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).
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.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
FLYING METAL can injure eyes.
Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use ap-
proved air-supplied respirator.
Allow cooling period before maintaining.
Wear protective gloves and clothing when
working on a hot engine.
Do not touch hot engine parts or just-welded
parts bare-handed.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
Wear approved ear protection if noise level is
high.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
Wearers should consult their doctor before
going near arc welding, gouging, or spot
welding operations.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the welding
process, be sure to treat them carefully.
Protect compressed gas cylinders from excessive heat,
mechanical shocks, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder − explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.
1-3.Engine Hazards

1-6.EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic 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 powerfrequency 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.

tions du fabricant concernant les métaux, les consommables, les
revêtements, les nettoyants et les dégraisseurs.
Travailler dans un espace fermé seulement s’il est bien ventilé ou en por-
tant un respirateur à alimentation d’air. Demander toujours à un surveillant
dûment formé de se tenir à proximité. Des fumées et des gaz de soudage
peuvent déplacer l’air et abaisser le niveau d’oxygène provoquant des
blessures ou des accidents mortels. S’assurer que l’air de respiration ne
présente aucun danger.
Ne pas souder dans des endroits situés à proximité d’opérations de dé-
graissage, de nettoyage ou de pulvérisation. La chaleur et les rayons de
l’arc peuvent réagir en présence de vapeurs et former des gaz hautement
toxiques et irritants.
Ne pas souder des métaux munis d’un revêtement, tels que l’acier galvani-
sé, plaqué en plomb ou au cadmium à moins que le revêtement n’ait été
enlevé dans la zone de soudure, que l’endroit soit bien ventilé, et si nécessaire, en portant un respirateur à alimentation d’air. Les revêtements et
tous les métaux renfermant ces éléments peuvent dégager des fumées
toxiques en cas de soudage.

LE SOUDAGE peut provoquer un incendie ou une explosion.
DES PIÈCES CHAUDES peuvent
provoquer des brûlures graves.
Le soudage effectué sur des conteneurs fermés tels que
des réservoirs, tambours ou des conduites peut provoquer
l’arc de soudure. La projection d’étincelles, des pièces chaudes et des
équipements chauds peut provoquer des incendies et des brûlures. Le contact
accidentel de l’électrode avec des objets métalliques peut provoquer des
étincelles, une explosion, un surchauffement ou un incendie. Avant de
commencer le soudage, vérifier et s’assurer que l’endroit ne présente pas de
danger.
Se protéger et d’autres personnes de la projection d’étincelles et de métal
chaud.
Ne pas souder dans un endroit là où des étincelles peuvent tomber sur des
substances inflammables.
Déplacer toutes les substances inflammables à une distance de 10,7 m de
l’arc de soudage. En cas d’impossibilité les recouvrir soigneusement avec
des protections homologués.
Des étincelles et des matériaux chauds du soudage peuvent facilement
passer dans d’autres zones en traversant de petites fissures et des
ouvertures.
Surveiller tout déclenchement d’incendie et tenir un extincteur à proximité.
Le soudage effectué sur un plafond, plancher, paroi ou séparation peut dé-
clencher un incendie de l’autre côté.
Ne pas effectuer le soudage sur des conteneurs fermés tels que des réser-
voirs, tambours, ou conduites, à moins qu’ils n’aient été préparés
correctement conformément à AWS F4.1 (voir les normes de sécurité).

1-6.Information sur les champs électromagnétiques
Données sur le soudage électrique et sur les effets, 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 électromagnétiques pendant le soudage ou le coupage.
Afin de réduire les champs électromagnétiques dans l’environnement
de travail, respecter les consignes suivantes :
1 Garder les câbles ensembles en les torsadant ou en les
attachant avec du ruban adhésif.
2 Mettre tous les câbles du côté opposé de l’opérateur.
3 Ne pas courber pas et ne pas entourer pas les câbles autour de
votre corps.
4 Garder le poste de soudage et les câbles le plus loin possible
de vous.
5 Relier 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 9 − RUN-IN PROCEDURE
1 Welding Generator
Run diesel engines near rated
output during run-in period to properly seat piston rings and prevent
wetstacking. See nameplate or
rating label to find rated output.
Do not idle engine longer than
2
1
necessary. Piston rings seat
faster if engine runs at weld/
power rpm, and the welding
generator is kept loaded during run-in.
2 Engine Exhaust Pipe
Wetstacking is unburned fuel and
oil in the exhaust pipe and occurs
during run-in if the engine is run too
long at light load or idle rpm.
If exhaust pipe is coated with a
wet, black, tar-like substance, dry
the engine using one of the following run-in procedures.
See the engine manual for additional engine run-in information.

1 Resistive Load
A light bulb is a resistive load and
requires a constant amount of
power.
2 Non-Resistive Load
Equipment with a motor is a non-
resistive load and requires approximately six times more power while
starting the motor than when running (see Section 10-8).
3 Rating Data
Rating shows volts and amperes,
or watts required to run equipment.
EXAMPLE 2: If three 200 watt flood lamps are used with the drill from Example 1,
add the individual loads to calculate total load.
OM-129 647 Page 46
(200 W + 200 W + 200 W) + 520 W = 1120 W
The total load applied by the three flood lamps and drill is 1120 watts.

1. Items furnished by Miller, but manufactured by others,
such as engines or trade accessories. These items are

2. Consumable components; such as contact tips, cutting
nozzles, contactors, brushes, slip rings, relays or parts
that fail due to normal wear.
3. Equipment that has been modified by any party other
than Miller, or equipment that has been improperly
installed, improperly operated or misused based upon

appropriate cases, (3) the reasonable cost of repair or
replacement at an authorized Miller service station; or (4)
payment of or credit for the purchase price (less reasonable

at customer’s risk and expense. Miller’s option of repair or
replacement will be F.O.B., Factory at Appleton, Wisconsin, or
F.O.B. at a Miller authorized service facility as determined by
Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.
TO THE EXTENT PERMITTED BY LAW, THE REMEDIES

Some states in the U.S.A. do not allow limitations of how long
an implied warranty lasts, or the exclusion of incidental,
indirect, special or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty
provides specific legal rights, and other rights may be
available, but may vary from state to state.
In Canada, legislation in some provinces provides for certain
additional warranties or remedies other than as stated herein,
and to the extent that they may not be waived, the limitations
and exclusions set out above may not apply. This Limited
Warranty provides specific legal rights, and other rights may
be available, but may vary from province to province.
