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
equipment manufacturer in exact part you may need to fix the problem.

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.

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-2222 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.

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-2222 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-2222 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.
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 stimulateurs cardiaques
Les porteurs de stimulateur cardiaque doivent consulter leur médecin
avant de souder ou d’approcher des opérations de soudage. 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. Durning 2T operation, a momentary closure (greater than 100 ms, but
less than 3/4 seconds) starts and stops weld output.
B - Closure to D turns on gas. This input will override Postflow, but if a Preflow time is entered, the Preflow cycle will time out before arc initiation.
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 transistors.
Final Slope - output is on when in Final Slope.
Pulse Lockout - output is on when in Initial Amperage, Initial Slope, Final Slope, Final Amperage, and when the pulse frequency is less than 10
Hz.
Arc On - output is on when the contactor is on and there is less than 50 load volts.

NOTE: Peak amperage is set using
the Amperage control (see Section
5-3). Peak amperage is the highest
welding amperage allowed in the
pulse cycle. Weld penetration varies
directly with peak amperage.
Application:
Pulsing is 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 better control of
penetration, bead width, crowning,
undercutting, and heat input.

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 weld area, and aids in arc starts.
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:
. Some features shown are
not available on all models.
1
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 DC 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 - To activate the gas valve and
start the purge function, push and hold
the Adjust switch pad for the desired
amount of time. To set from 1 to 50 seconds of purge time, hold the Adjust switch
pad while turning the encoder control.
Default is 0.
While Purge is active, (-P-) is shown in the
left display, and purge time is shown in
the right display.
Pressing any switch pad will end the
purge display, but gas will continue to flow
until the preset time has timed out.
Application: Purge is used to clear the

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.

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:
Do NOT Strike Like A Match!
Lift-Arc is used for the DCEN or AC
GTAW process when HF Start
method is not permitted, or to replace the scratch method.
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.

12-15. Troubleshooting − Porosity
Porosity − small cavities or holes resulting from gas
pockets in weld metal.
Possible Causes
Corrective Actions
Arc length too long.
Reduce arc length.
Damp electrode.
Use dry electrode.
Workpiece dirty.
Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before
welding.
12-16. Troubleshooting − Excessive Spatter
Excessive Spatter − scattering of molten metal particles
that cool to solid form near weld bead.
Possible Causes
Corrective Actions
Amperage too high for electrode.
Decrease amperage or select larger electrode.
Arc length too long or voltage too high.
Reduce arc length or voltage.
OM-2222 Page 69
12-17. Troubleshooting − Incomplete Fusion
Incomplete Fusion − failure of weld metal to fuse completely with
base metal or a preceeding weld bead.
Possible Causes
Corrective Actions
Insufficient heat input.
Increase amperage. Select larger electrode and increase amperage.
Improper welding technique.
Place stringer bead in proper location(s) at joint during welding.
Adjust work angle or widen groove to access bottom during welding.
Momentarily hold arc on groove side walls when using weaving technique.
Keep arc on leading edge of weld puddle.
Workpiece dirty.
Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before
welding.
12-18. Troubleshooting − Lack Of Penetration
Lack Of Penetration − shallow fusion between weld metal and
base metal.
Lack of Penetration
Good Penetration
Possible Causes
Corrective Actions
Improper joint preparation.
Material too thick. Joint preparation and design must provide access to bottom of groove.
Improper weld technique.
Keep arc on leading edge of weld puddle.
Insufficient heat input.
Increase amperage. Select larger electrode and increase amperage.
Reduce travel speed.
12-19. Troubleshooting − Excessive Penetration
Excessive Penetration − weld metal melting through base metal and
hanging underneath weld.
Excessive Penetration
Possible Causes
Excessive heat input.
Good Penetration
Corrective Actions
Select lower amperage. Use smaller electrode.
Increase and/or maintain steady travel speed.
OM-2222 Page 70
12-20. Troubleshooting − Burn-Through
Burn-Through − weld metal melting completely through base metal resulting
in holes where no metal remains.
Possible Causes
Excessive heat input.
Corrective Actions
Select lower amperage. Use smaller electrode.
Increase and/or maintain steady travel speed.
12-21. Troubleshooting − Waviness Of Bead
Waviness Of Bead − weld metal that is not parallel and does not cover
joint formed by base metal.
Possible Causes
Unsteady hand.
Corrective Actions
Use two hands. Practice technique.
12-22. Troubleshooting − Distortion
Distortion − contraction of weld metal during welding that forces base
metal to move.
Base metal moves
in the direction of
the weld bead.
Possible Causes
Excessive heat input.
Corrective Actions
Use restraint (clamp) to hold base metal in position.
Make tack welds along joint before starting welding operation.
Select lower amperage for electrode.
Increase travel speed.
Weld in small segments and allow cooling between welds.
