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 parts list
will then help you to decide which exact part
you may need to fix the problem. Warranty and
service information for your particular model
are also provided.
Miller is the first welding
equipment manufacturer in
the U.S.A. to be registered to
the ISO 9001 Quality System
Standard.
Working as hard as you do
– every power source from
Miller is backed by the most
hassle-free warranty in the
business.
From Miller to You
Miller offers a Technical
Manual which provides
more detailed service and
parts information for your
unit. To obtain a Technical
Manual, contact your local
distributor. Your distributor
can also supply you with
Welding Process Manuals
such as SMAW, GTAW,
GMAW, and GMAW-P.

SECTION 1 – SAFETY PRECAUTIONS – READ BEFORE USING
1-1. Symbol Usage
OM-1521H -3/97, safety_gmaw_gun 3/97
Means Warning! Watch Out! There are possible hazards
with this procedure! The possible hazards are shown in
the adjoining symbols.
Y Marks a special safety message.
. Means “Note”; not safety related.
This group of symbols means Warning! Watch Out! possible
ELECTRIC SHOCK, WELDING WIRE, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary actions
to avoid the hazards.
1-2. Arc Welding Hazards
Y 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 the wire feeder and welding
power source Owner’s Manuals. Read and follow all Safety
Standards.
Y Only qualified persons should install, operate, maintain, and
repair this unit.
Y During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
D Always wear dry insulating gloves.
D Insulate yourself from work and ground.
D Do not touch live electrode or electrical parts.
D Repair or replace worn, damaged, or cracked
gun or cable insulation.
D Turn off welding power source before changing contact tip or gun
parts.
D Keep all covers and handle securely in place.
FUMES AND GASES can be hazardous.
D Keep your head out of the fumes.
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 explo-
sion.
D Do not weld near flammable material.
D Do not weld on closed containers.
D Watch for fire; keep extinguisher nearby.
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 burn skin.
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.
D Some applications, such as pulsing, are noisy.
D Check for noise level limits exceeding those
specified by OSHA.
D Use approved ear plugs or ear muffs if noise level is high.
D Warn others nearby about noise hazard.
WELDING WIRE can cause injury.
D Keep hands and body away from gun tip when
trigger is pressed.
D Do not point gun toward any part of the body,
other people, or any metal when threading
welding wire.
1-3. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the
U.S. Congress, Office of Technology Assessment, Biological Effects of
Power Frequency Electric & Magnetic Fields – Background Paper,
OTA-BP-E-53 (Washington, DC: U.S. Government Printing Office, May
1989): “. . . there is now a very large volume of scientific findings based
on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields can
interact with, and produce changes in, biological systems. While most
of this work is of very high quality, the results are complex. Current
scientific understanding does not yet allow us to interpret the evidence
in a single coherent framework. Even more frustrating, it does not yet
allow us to draw definite conclusions about questions of possible risk
or to offer clear science-based advice on strategies to minimize or avoid
potential risks.”
To reduce magnetic fields in the workplace, use the following
procedures:
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 the body.
4. Keep welding power source and cables as far away from opera-
tor as practical.
5. Connect work clamp to workpiece as close to the weld as possi-
ble.
About Pacemakers:
The above procedures are also recommended for pacemaker wearers.
Consult your doctor for complete information.
