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.
Today, the people that build and sell Miller products continue the
tradition. They’re just as committed to providing equipment and service
that meets the high standards of quality and value established in 1929.
This Owner’s Manual is designed to help you get the most out of your
Miller products. Please take time to read the Safety precautions. They
will help you protect yourself against potential hazards on the worksite.
We’ve made installation and operation quick
and easy. With Miller you can count on years
of reliable service with proper maintenance.
And if for some reason the unit needs repair,
there’s a Troubleshooting section that will
help you figure out what the problem is. The
Miller is the first welding parts list will then help you to decide the

Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
D 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.
D When making input connections, attach proper grounding conductor first − double-check connections.
D Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
D Frequently inspect input power cord for damage or bare wiring −
replace cord immediately if damaged − bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
D Do not drape cables over your body.
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.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
D Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on
unit.
D Additional safety precautions are required when any of the following electrically hazardous conditions are present: 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; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!
D 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).
D Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
D If earth grounding of the workpiece is required, ground it directly
with a separate cable.
D Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
D Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be
present.
D Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
D Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
D Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
D Do not connect more than one electrode or work cable to any
single weld output terminal.

wear heavy, insulated welding gloves and
clothing to prevent burns.
OM-2226 Page 1
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 local forced ventilation at the
arc to remove welding fumes and gases.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand 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 the oxygen level causing injury or death. Be sure the breathing air is safe.
D 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.
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 while wearing an air-supplied
respirator. The coatings and any metals containing these elements
can give off toxic fumes if welded.
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.
D Wear an approved welding helmet fitted with a proper shade of filter lenses 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 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.
D Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
D Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
D After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
D Use only correct fuses or circuit breakers. Do not oversize or bypass them.
D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
FLYING METAL or DIRT can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
D Shut off shielding gas supply when not in use.
D Always ventilate confined spaces or use
approved air-supplied respirator.
MAGNETIC FIELDS can affect Implanted
Medical Devices.
D Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
D Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
D Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
NOISE can damage hearing.
D Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton, or wool) and foot protection.
Noise from some processes or equipment can
damage hearing.
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.
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 Do not weld where flying sparks can strike flammable material.
D Protect yourself and others from flying sparks and hot metal.
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 Do not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).
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, sparks, and fire
hazards.
OM-2226 Page 2
D Wear approved ear protection if noise level is
high.
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.
D Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.
D Never drape a welding torch over a gas cylinder.
D Never allow a welding electrode to touch any cylinder.

1-6. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
1. Keep cables close together by twisting or taping them, or using a
cable cover.
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.
2. Arrange cables to one side and away from the operator.
To reduce magnetic fields in the workplace, use the following
procedures:
OM-2226 Page 4
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 Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recommended.

sur des substances inflammables.
LES FUMÉES ET LES GAZ peuvent être
dangereux.
D Se protéger et d’autres personnes de la projection d’étincelles et
de métal chaud.
Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereux pour votre santé.
D Des étincelles et des matériaux chauds du soudage peuvent
facilement passer dans d’autres zones en traversant de petites
fissures et des ouvertures.
D Eloigner votre tête des fumées. Ne pas respirer les fumées.
D Surveiller tout déclenchement d’incendie et tenir un extincteur à
proximité.
D À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au
niveau de l’arc pour l’évacuation des fumées et des gaz de soudage.
D Le soudage effectué sur un plafond, plancher, paroi ou séparation
peut déclencher un incendie de l’autre côté.
D Si la ventilation est médiocre, porter un respirateur anti-vapeurs
approuvé.
D Ne pas effectuer le soudage sur des conteneurs fermés tels que

préparés correctement conformément à AWS F4.1 (voir les normes de sécurité).
D Lire et comprendre les spécifications de sécurité des matériaux
(MSDS) et les instructions du fabricant concernant les métaux, les
consommables, les revêtements, les nettoyants et les dégraisseurs.
D Ne soudez pas si l’air ambiant est chargé de particules, gaz, ou vapeurs inflammables (vapeur d’essence, par exemple).
D 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.
D Brancher le câble de masse 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, d’étincelles et d’incendie.
D 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.
D En cas de non utilisation, enlever la baguette d’électrode du porteélectrode ou couper le fil à la pointe de contact.
D 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 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.
LES RAYONS DE L’ARC peuvent
provoquer des brûlures dans les
yeux et sur la peau.
Le rayonnement de l’arc du procédé de soudage
génère des rayons visibles et invisibles intense
(ultraviolets et infrarouges) susceptibles de provoquer des brûlure
dans les yeux et sur la peau. Des étincelles sont projetées pendant le
soudage.

2-6. Information EMF
Considérations sur le soudage et les effets de basse fréquence et des
champs magnétiques et électriques.
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.
Pour réduire les champs magnétiques sur le poste de travail, appliquer
les procédures suivantes :
1. Garder les câbles ensemble, les torsader, les scotcher, ou les
recouvrir d’une housse.
2. Disposer les câbles d’un côté et à distance 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. Connecter la pince sur la pièce aussi près que possible de la
soudure.
En ce qui concerne les implants médicaux :
Les porteurs d’implants doivent d’abord consulter leur médecin avant
de s’approcher des opérations de soudage à l’arc, de soudage par
points, de gougeage, du coupage plasma ou de chauffage par induction. Si le médecin approuve, il est recommandé de suivre les
procédures précédentes.

Definitions Of Inputs And Outputs
Inputs
A - Closure to D starts the weld cycle. Opening closure stops weld cycle. During 2T operation, a momentary closure (greater than 100ms, but
less than 3/4 seconds) starts and stops weld output.
B - Closure to D turns on gas. If a preflow time is entered, the preflow cycle will time out before arc initiation. If a post flow time is entered, the
post flow cycle will time out at the end of the weld, even if B to D closure is opened.
C - Closure to D must be maintained at all times. If the closure between pins C and D is broken, an output disable occurs, Postflow begins to
time out, and HELP 13 will be displayed on the meters.
Outputs
Outputs are isolated open-collector transistor which are able to conduct at least 60 mA of current and 27 VDC peak.
Final Slope - output is on when in Final Slope.
Pulse Lockout - output is on when in Initial Amperage, Initial Slope, Final Slope, Final Amperage, during background time, and when the pulse
frequency is less than 10 Hz.
Arc On - output is on when the contactor is on and amperage is greater than 5 amps, or output voltage is greater than 5 volts but less than 50
volts.

“Touch”
1−2
Seconds
2
1
TIG Electrode
2
Workpiece
Touch tungsten electrode to workpiece at weld start
point, enable output and shielding gas with torch
trigger, foot control, or hand control. Hold electrode
to workpiece for 1-2 seconds, and slowly lift electrode. Arc is formed when electrode is lifted.
Normal open-circuit voltage is not present before
tungsten electrode touches workpiece; only a low
sensing voltage is present between electrode and
workpiece. The solid-state output contactor does
not energize until after electrode is touching workpiece. This allows electrode to touch workpiece
without overheating, sticking, or getting
contaminated.
Application:
Lift-Arc is used for the DCEN or AC GTAW process
when HF Start method is not permitted, or to replace
the scratch method.
Do NOT Strike Like A Match!
HF Start
When HF Start button light is On, start arc as
follows:
High frequency turns on to help start arc when output is enabled. High frequency turns off when arc is
started, and turns on whenever arc is broken to help
restart arc.
Application:
HF start is used for the DCEN GTAW process when
a non-contact arc starting method is required.

Pulsing refers to the alternating raising and lowering of the weld output at
a specific rate. The raised portions of
the weld output are controlled in
width, height, and frequency, forming
pulses of weld output. These pulses
and the lower amperage level between them (called the background
amperage) alternately heat and cool
the molten weld puddle. The combined effect gives the operator better
control of penetration, bead width,
crowning, undercutting, and heat input. Controls can be adjusted while
welding.
Pulsing can also be used for filler material addition technique training.

Turn encoder (see Section 5-2) to set appropriate value for active Adjust parameter. Value selected is shown on the ammeter (see Section 5-4). Also, the ammeter LED for the corresponding unit of
measure (S, %) of the active parameter
will be illuminated.
See Section 5-14 for all Adjust parameter ranges.
PREFLOW - If the TIG HF process is active (see Section 5-6) and Preflow is
shown on the control panel, use control
to set length of time gas flows before arc
initiation. To set Preflow time for models
that do not have Preflow Time control on
the front panel, see Section 5-13.
Application: Preflow is used to purge
the immediate weld area of atmosphere.
Preflow also aids in consistent arc starts.
1
POST FLOW - If the TIG process is active (see Section 5-6), use control to set
length of time gas flows after welding
stops.
Application:
Postflow is required to cool tungsten and
weld, and to prevent contamination of
tungsten and weld. Increase postflow
time if tungsten or weld are dark in appearance.
DIG - If the Stick process is active (see
Section 5-6), use control to set amount of
DIG. When set at 0, short-circuit amperage at low arc voltage is the same as normal welding amperage.
When setting is increased, short-circuit
amperage at low arc voltage increases.
Application:
Control helps arc starting or making vertical or overhead welds by increasing
amperage at low arc voltage, and reduces electrode sticking while welding.
PURGE - While in the TIG process (see
Section 5-6), to activate the gas valve
and start the purge function, push and
hold the Adjust switch pad for the desired
amount of purge time. To set from 0 to 50
seconds of additional purge time, continue to hold the Adjust switch pad while
turning the encoder control. Factory default setting is 0.
While Purge is active, (PUR) is shown in
the left display, and purge time is shown
in the right display.
Pressing any front panel switch pad will
end the purge time display, but gas will
continue to flow until the preset time has
timed out.
Application: Purge is used to clear the
shielding gas lines of contaminates.

3T (Specific Trigger Operation)
Sequencer is required to reconfigure for 3T.
3T requires two independent momentarycontact switches. One will be designated initial switch, and it must be connected between
Remote 14 receptacle pins A and B. The second will be designated as the final switch, and
it must be connected between Remote 14 receptacle pins D and E.
Select 3T according to Section 6-2C.
Definitions:
Initial slope rate is the rate of amperage
change determined by the initial amperage,
initial slope time, and main amperage.
Final slope rate is the rate of amperage
change determined by the main amperage, final slope time, and final amperage.
Operation:
A..Press and release initial switch within 3/4
second to start shielding gas flow. To stop
the preflow sequence before preflow time
elapses (25 seconds), press and release
final switch. The preflow timer will reset
and the weld sequence can be started
again.
. If an initial switch closure is not made
again before preflow time ends, gas flow
stops, the timer resets, and an initial
switch press and release is necessary to
start the weld sequence again.
B..Press initial switch to start arc at initial
amps. Holding switch will change amperage at initial slope rate (release switch to
weld at desired amperage level).
C..When main amperage level is reached,
initial switch can be released.
D..Press and hold the final switch to decrease amperage at final slope rate (release switch to weld at desired amperage
level).
E.. When final amperage has been reached,
the arc extinguishes and shielding gas
flows for the time set on the Postflow control.
Application:
With the use of two remote switches instead
of potentiometers, 3T gives the operator the
ability to infinitely increase, decrease, or
pause and hold amperage within the range
determined by the initial, main, and final amperages.

additional warranties or remedies other than as stated herein,
