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.

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 welding power source Owner’s Manual. Read
and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and

D Ventilate area, or use breathing device.
D Read Material Safety Data Sheets (MSDSs)
and manufacturer’s instructions for material
used.
WELDING can cause fire or explosion.
D Do not weld near flammable material.
D Do not weld on closed containers.
D Watch for fire; keep extinguisher nearby.
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.
ARC RAYS can burn eyes and skin.
D Wear welding helmet with correct shade of filter.
D Wear correct eye and body protection.
D Cover exposed skin with spatter-resistant
clothing.
HOT PARTS can cause severe burns.
D Allow gun to cool before touching.
D Do not touch hot metal.
D Protect hot metal from contact by others.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
D Check for noise level limits exceeding those
specified by OSHA.

1-3. 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-227 398 Page 2
1. Keep cables close together by twisting or taping them, or using a
cable cover.
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 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.

are possible hazards as
shown by the symbols.
B. Drive rolls can injure fingers.
C. Welding wire and drive parts
are at welding voltage during
operation − keep hands and
metal objects clear.
1 Electric shock can kill.
1.1 Wear dry insulating gloves.
Do not touch electrode with
bare hand. Do not wear wet or
damaged gloves.
1.2 Protect yourself from electric
shock by insulating yourself
from work and ground.
1.3 Disconnect input plug or
power before working on

2 Breathing welding fumes can
be hazardous to your health.
2.1 Keep your head out of the
fumes.
2.2 Use forced ventilation or local
exhaust to remove the fumes.
2.3 Use ventilating fan to remove
fumes.
3 Welding sparks can cause
explosion or fire.
3.1 Keep flammables away from
welding. Don’t weld near
flammables.
3.2 Welding sparks can cause
fires. Have a fire extinguisher
nearby and have a watch
person ready to use it.
3.3 Do not weld on drums or any
closed containers.
4 Arc rays can burn eyes and
injure skin.
4.1 Wear hat and safety glasses.
Use ear protection and button
shirt collar. Use welding
helmet with correct shade of
filter. Wear complete body
protection.
5 Become trained and read the
instructions before working on
the machine or welding.

!
Welding wire is electrically live when
gun trigger is used to jog wire.
. Turn OFF coolant supply before threading wire
through gun..
Lay gun cable out straight. Press Jog switch until about 6
in (152 mm) of wire is sticking out end of contact tip.
. Verify pressure adjustment
on handle matches the wire
type. See Section 5-2.
Cut off wire. Close and
latch wire feeder door.

2.
Items furnished by Miller, but manufactured by others, such

3.
Equipment that has been modified by any party other than

In the event of a warranty claim covered by this warranty, the

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.
