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

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 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 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.
Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be
present.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
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 in inverter-type
welding power sources after removal of input
power.
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 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.
OM-230 693 Page 1
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 Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton, or 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
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 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.
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 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 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.
OM-230 693 Page 2
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.
HOT PARTS can cause severe burns.
D Do not touch hot parts bare handed.
D Allow cooling period before working on gun or
torch.
D To handle hot parts, use proper tools and/or
wear heavy, insulated welding gloves and
clothing to prevent burns.
MAGNETIC FIELDS can affect pacemakers.
D Pacemaker wearers keep away.
D Wearers should consult their doctor before
going near arc welding, gouging, or spot
welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
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.
D Never weld on a pressurized cylinder − explosion will result.
D Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and
associated parts in good condition.
D Turn face away from valve outlet when opening cylinder valve.
D Keep protective cap in place over valve except when cylinder is in
use or connected for use.
D Use the right equipment, correct procedures, and sufficient number of persons to lift and move cylinders.
D Read and follow instructions on compressed gas cylinders,
associated equipment, and Compressed Gas Association (CGA)
publication P-1 listed in Safety Standards.

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-230 693 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 before welding or going near
welding operations. If cleared by your doctor, then following the above
procedures is recommended.

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 :
OM-230 693 Page 8
1. Maintenir les câbles ensemble en les tordant ou en les enveloppant.
2. Disposer les câbles d’un côté et à distance de l’opérateur.

1 Choose a circuit breaker with time-current curves comparable to a Time Delay Fuse.
2 “Time-Delay” fuses are UL class “RK5” .
3 “Normal Operating” (general purpose − no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.
Y Warning: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard. These
recommendations are for a dedicated branch circuit that applies to the rated output and duty cycle of the welding power source.

JOG Mode
If the trigger on either gun is held for more
than 3 seconds without striking an arc, the
unit will automatically shut off weld power
(and shielding gas output on MIG gun
only), but will feed wire continuously at the
preset wire feed speed (which may be
faster or slower than Run−in Speed) until
trigger is released.
Run−in Wire Feed Speed Settings
Run−in settings for the MIG and Spool
Guns are independently set and stored in
unit memory. The settings are in percent of
the welding wire feed speed preset. Both
settings are adjustable from 25 to 150
percent.
MIG Gun Run−in is factory set at 100%
which is recommended for most wire sizes
and types.
Spool Gun Run−in is factory set at 50%
which is recommended for .030 & .035
wire. A Run−in setting of 25% is
recommended for .047 wire.
To check Run−in settings, start with the
power switch OFF. Press and hold the MIG
or Spool Gun Trigger while turning the
power switch ON. The unit will power up
with both the displays reading 888 , then
the voltage display will read run and the
wire feed display will read the preset
Run−in percentage from memory for the
gun selected. To return to the weld mode
without making a change, simply release
trigger and pull the trigger
momentarily (one second).
again
To change Run−in settings, start with the
power switch OFF. Press and hold the MIG
or Spool Gun Trigger while turning the
power switch ON. The unit will power up
with both the displays reading 888 , then
the voltage display will read run and the
wire feed display will read the preset Run−
in percentage from memory for the gun selected. To change the Run−in value, release the trigger and turn the wire feed control knob (or the wire feed adjustment knob
located on the bottom handle of the spool
gun) to the desired setting for the selected
gun. To return to weld mode after the Run−
in speed change, pull the trigger momentarily (one second).

Wire Feed Speed Meter
When either a MIG gun or spool gun trigger
is pressed and a welding arc is established,
the voltmeter displays actual weld voltage.
When the gun trigger is released and
welding arc extinguished, the voltmeter
displays the last actual voltage for 5
seconds and then returns to preset voltage.
If welding resumes before unit displays
preset voltage, actual welding voltage will
appear on the voltmeter.
Power Up Status
Both meters display 888 at unit power up.
After 0.5 seconds, preset values appear on
both meters. The settings for the last active
gun used will be the default at initial power
up of the unit. If the power is reset to quickly,
characters other than 888 may appear. To
reset, turn power off for at least 3 seconds,
then turn power back on.
The wire feed speed meter always displays
preset wire feed speed (IPM).
2
Gun Selection
The wire feed speed meter will display
preset wire feed speed (IPM) for the
appropriate gun selection either MIG,
Spool or Push/Pull gun. To preset desired
wire feed speed, connect desired gun,
press gun trigger for one second, and
release trigger. The meter preset will be
retained by the meter board until a different
gun is connected and preset is performed
or the unit is turned off and back on. The
settings for the last active gun used will be
the default at initial power up of the unit.
5-3. Jog Mode
If the trigger on either gun is held for more than 3 seconds without striking an arc, the unit will automatically shut off
weld power (and shielding gas output on MIG or push/pull gun), but will feed wire continuously at the preset wire feed
speed (which may be faster or slower than Run−in Speed) until trigger is released. Jog wire feed speed is the same as
weld wire feed speed, so any time jog speed is changed, be sure to change back to weld wire feed speed before welding. Jog wire feed speed for the spool gun and push/pull gun is limited to 300 ipm (7.6 m/min).
