From Miller to You
Thank you and congratulations on choosing Miller. Now
you can get the job done and get it done right. We know
you don’t have time to do it any other way.
That’s why when Niels Miller first started building arc
welders in 1929, he made sure his products offered
long-lasting value and superior quality. Like you, his
customers couldn’t afford anything less. Miller products
had to be more than the best they could be. They had to
be the best you could buy.

1-1. Symbol Usage
Means Warning! Watch Out! There are possible hazards
with this procedure! The possible hazards are shown in
the adjoining symbols.
Marks a special safety message.
Means “Note”; not safety related.
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.
1-2. Arc Welding Hazards
The symbols shown below are used throughout this manual to
call attention to and identify possible hazards. When you see
the symbol, watch out, and follow the related instructions to
avoid the hazard. The safety information given below is only
a summary of the more complete safety information found in
the Safety Standards listed in Section 1-5. Read and follow all
Safety Standards.
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 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.
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.
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.
OM-491 Page 1
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
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.
HOT PARTS can cause severe burns.
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.
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.
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.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
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.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs.
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 approved air-supplied respirator.
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
FUEL can cause fire or explosion.
Stop engine and let it cool off before checking or
adding fuel.
Do not add fuel while smoking or if unit is near
any sparks or open flames.
Do not overfill tank − allow room for fuel to expand.
Do not spill fuel. If fuel is spilled, clean up before starting engine.
Dispose of rags in a fireproof container.

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:
OM-491 Page 4
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.

LES RAYONS DE L’ARC peuvent provoquer des brûlures dans les yeux et
sur la peau.
UN CHOC ÉLECTRIQUE peut tuer.
Un simple contact avec des pièces électriques peut
provoquer une électrocution ou des blessures graves.
L’électrode et le circuit de soudage sont sous tension dès
que l’appareil est sur ON. Le circuit d’entrée et les circuits
internes de l’appareil sont également sous tension à ce
moment-là. En soudage semi-automatique ou automatique, le fil, le dévidoir, le
logement des galets d’entraînement et les pièces métalliques en contact avec
le fil de soudage sont sous tension. Des matériels mal installés ou mal mis à la
terre présentent un danger.
Ne jamais toucher les pièces électriques sous tension.
Porter des gants et des vêtements de protection secs ne comportant pas
de trous.
S’isoler de la pièce et de la terre au moyen de tapis ou d’autres moyens isolants suffisamment grands pour empêcher le contact physique éventuel
avec la pièce ou la terre.
Ne pas se servir de source électrique àcourant électrique dans les zones
humides, dans les endroits confinés ou là où on risque de tomber.
Se servir d’une source électrique àcourant électrique UNIQUEMENT si le
procédé de soudage le demande.
Si l’utilisation d’une source électrique àcourant électrique s’avère nécessaire, se servir de la fonction de télécommande si l’appareil en est équipé.
Couper l’alimentation ou arrêter le moteur avant de procéder à l’installation,
à la réparation ou à l’entretien de l’appareil. Déverrouiller l’alimentation
selon la norme OSHA 29 CFR 1910.147 (voir normes de sécurité).
Installer et mettre à la terre correctement cet appareil conformément à son
manuel d’utilisation et aux codes nationaux, provinciaux et municipaux.
Toujours vérifier la terre du cordon d’alimentation − Vérifier et s’assurer que
le fil de terre du cordon d’alimentation est bien raccordé à la borne de terre
du sectionneur ou que la fiche du cordon est raccordée à une prise
correctement mise à la terre.
En effectuant les raccordements d’entrée fixer d’abord le conducteur de
mise à la terre approprié et contre-vérifier les connexions.
Vérifier fréquemment le cordon d’alimentation pour voir s’il n’est pas endommagé ou dénudé − remplacer le cordon immédiatement s’il est
endommagé − un câble dénudé peut provoquer une électrocution.
Mettre l’appareil hors tension quand on ne l’utilise pas.
Ne pas utiliser des câbles usés, endommagés, de grosseur insuffisante ou
mal épissés.
Ne pas enrouler les câbles autour du corps.
Si la pièce soudée doit être mise à la terre, le faire directement avec un
câble distinct − ne pas utiliser le connecteur de pièce ou le câble de retour.
Ne pas toucher l’électrode quand on est en contact avec la pièce, la terre ou
une électrode provenant d’une autre machine.
N’utiliser qu’un matériel en bon état. Réparer ou remplacer sur-le-champ
les pièces endommagées. Entretenir l’appareil conformément à ce
manuel.

la pièce à souder ou la table de travail, le plus près possible de la soudure.
Isoler la pince de masse quand pas mis à la pièce pour éviter le contact
avec tout objet métallique.
Le rayonnement de l’arc du procédé de soudage génère
des rayons visibles et invisibles intenses (ultraviolets et
infrarouges) susceptibles de provoquer des brûlures dans les yeux et sur la
peau. Des étincelles sont projetées pendant le soudage.
Porter un casque de soudage muni d’un écran de filtre approprié pour protéger votre visage et vos yeux pendant le soudage ou pour regarder (voir
ANSI Z49.1 et Z87.1 énuméré dans les normes de sécurité).
Porter des protections approuvés pour les oreilles si le niveau sondre est
trop élevé.
Utiliser des écrans ou des barrières pour protéger des tiers de l’éclair et de
l’éblouissement; demander aux autres personnes de ne pas regarder l’arc.
Porter des vêtements de protection constitué dans une matière durable, résistant au feu (laine ou cuir) et une protection des pieds.
LES FUMÉES ET LES GAZ peuvent
être dangereux.
Le soudage génère des fumées et des gaz. Leur inhalation
peut être dangereux pour votre santé.
Eloigner votre tête des fumées. Ne pas respirer les fumées.
À l’interieur, ventiler la zone et/ou utiliser un échappement au niveau de
l’arc pour l’évacuation des fumées et des gaz de soudage.
Si la ventilation est insuffisante, utiliser un respirateur à alimentation d’air
homologué.
Lire les spécifications de sécurité des matériaux (MSDSs) et les instructions 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 portant 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 dégraissage, 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 galvanisé, 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
OM-491 Page 5
tous les métaux renfermant ces éléments peuvent dégager des fumées
toxiques en cas de soudage.
DES PIÈCES CHAUDES peuvent
provoquer des brûlures graves.
LE SOUDAGE peut provoquer un incendie ou une explosion.
Le soudage effectué sur des conteneurs fermés tels que
des réservoirs, tambours ou des conduites peut provoquer
leur éclatement. Des étincelles peuvent être projetées de
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 déclencher un incendie de l’autre côté.
Ne pas effectuer le soudage sur des conteneurs fermés tels que des réservoirs, tambours, ou conduites, à moins qu’ils n’aient été préparés
correctement conformément à AWS F4.1 (voir les normes de sécurité).
Brancher le câble sur la pièce le plus près possible de la zone de soudage
pour éviter le transport du courant sur une longue distance par des chemins inconnus éventuels en provoquant des risques d’électrocution et
d’incendie.
Ne pas utiliser le poste de soudage pour dégeler des conduites gelées.
En cas de non utilisation, enlever la baguette d’électrode du porte-électrode ou couper le fil à la pointe de contact.
Porter des vêtements de protection dépourvus d’huile tels que des gants
en cuir, une chemise en matériau lourd, des pantalons sans revers, des
chaussures hautes et un couvre chef.
Avant de souder, retirer toute substance combustible de vos poches telles
qu’un allumeur au butane ou des allumettes.
DES PARTICULES VOLANTES
peuvent blesser les yeux.
Le soudage, l’écaillement, le passage de la pièce
à la brosse en fil de fer, et le meulage génèrent
des étincelles et des particules métalliques volantes. Pendant la période de refroidissement des soudures, elles risquent de projeter du laitier.
Porter des lunettes de sécurité avec écrans latéraux ou un écran facial.
LES ACCUMULATIONS DE GAZ risquent de provoquer des blessures ou
même la mort.
Fermer l’alimentation du gaz protecteur en cas de
non utilisation.
Veiller toujours à bien aérer les espaces confinés ou se servir d’un respirateur d’adduction d’air homologué.
Prévoir une période de refroidissement avant d’effectuer des travaux d’entretien.
Porter des gants et des vêtements de protection pour
travailler sur un moteur chaud.
Ne pas toucher à mains nues les parties chaudes du moteur ni les pièces
récemment soudées.
LE BRUIT peut affecter l’ouïe.
Le bruit des processus et des équipements peut affecter
l’ouïe.
Porter des protections approuvés pour les oreilles si
le niveau sondre est trop élevé.
LES CHAMPS MAGNÉTIQUES peuvent
affecter les stimulateurs cardiaques.
Porteurs de stimulateur cardiaque, restez à distance.
Les porteurs d’un stimulateur cardiaque doivent
d’abord consulter leur médecin avant de s’approcher
des opérations de soudage à l’arc, de gougeage ou
de soudage par points.
Si des BOUTEILLES sont endommagées, elles pourront exploser.
Des bouteilles de gaz protecteur contiennent du gaz sous
haute pression. Si une bouteille est endommagée, elle peut
exploser. Du fait que les bouteilles de gaz font normalement partie du procédé de soudage, les manipuler avec
précaution.
Protéger les bouteilles de gaz comprimé d’une chaleur excessive, des
chocs mécaniques, du laitier, des flammes ouvertes, des étincelles et des
arcs.
Placer les bouteilles debout en les fixant dans un support stationnaire ou
dans un porte-bouteilles pour les empêcher de tomber ou de se renverser.
Tenir les bouteilles éloignées des circuits de soudage ou autres circuits
électriques.
Ne jamais placer une torche de soudage sur une bouteille à gaz.
Une électrode de soudage ne doit jamais entrer en contact avec une bouteille.
Ne jamais souder une bouteille pressurisée − risque d’explosion.
Utiliser seulement des bouteilles de gaz protecteur, régulateurs, tuyaux et
raccords convenables pour cette application spécifique; les maintenir ainsi
que les éléments associés en bon état.
Ne pas tenir la tête en face de la sortie en ouvrant la soupape de la bouteille.
Maintenir le chapeau de protection sur la soupape, sauf en cas d’utilisation
ou de branchement de la bouteille.

Données sur le soudage électrique et sur les effets, pour l’organisme,
des champs magnétiques basse fréquence
Afin de réduire les champs électromagnétiques dans l’environnement
de travail, respecter les consignes suivantes :
1
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.

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
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.

Rating Data
Rating shows volts and amperes,
or watts required to run equipment.
AMPERES x VOLTS = WATTS
EXAMPLE 1: If a drill uses 4.5 amperes at 115 volts, calculate its running power
requirement in watts.
4.5 A x 115 V = 520 W
The load applied by the drill is 520 watts.
EXAMPLE 2: If three 200 watt flood lamps are used with the drill from Example 1,
add the individual loads to calculate total load.
(200 W + 200 W + 200 W) + 520 W = 1120 W
The total load applied by the three flood lamps and drill is 1120 watts.

To find starting amperage:
Step 1: Find code and use table to
find kVA/HP. If code is not listed,
multiply running amperage by six to
find starting amperage.
Step 2: Find Motor HP and Volts.
Step 3: Determine starting amperage (see example).
Welding generator amperage output must be at least twice the
motor’s running amperage.

EXAMPLE: Calculate the starting amperage required for a 230 V, 1/4
HP motor with a motor start code of M.
Volts = 230
HP = 1/4
Using Table, Code M results in kVA/HP = 11.2
11.2 x 1/4 x 1000
= 12.2 A Starting the motor requires 12.2 amperes.

Limit Load To 90% Of
Generator Output
Always start non-resistive (motor)
loads in order from largest to smallest, and add resistive loads last.

5 Second Rule
If motor does not start within 5
seconds, turn off power to prevent
motor damage. Motor requires
more power than generator can
supply.

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,
