avoid the hazards.
1-2. Arc Welding Hazards
WARNING
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 Section 1-4. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and repair this unit.
During operation, keep everybody, especially children, away.
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. Incorrectly installed or
improperly grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the
work or ground.
4. Disconnect input power before installing or servicing this
equipment. Lockout/tagout input power according to OSHA 29
CFR 1910.147 (see Safety Standards).
5. Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
6. Always verify the supply ground – check and be sure that input
power cord ground wire is properly connected to ground terminal
ARC RAYS can burn eyes and skin;
NOISE can damage hearing; FLYING
SLAG OR SPARKS can injure eyes.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Noise from some
processes can damage hearing. Chipping, grinding,
and welds cooling throw off pieces of metal or slag.
NOISE
be
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals, consumables, coatings,
cleaners, and degreasers.

2. Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes when welding or watching (see ANSI Z49.1
and Z87.1 listed in Safety Standards).
3. Wear approved safety glasses with side shields.
4. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
5. Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
1. Use approved ear plugs or ear muffs if noise level is high.
FUMES AND GASES can

7.
in disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
When making input connections, attach proper grounding
conductor first – double-check connections.
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 use work clamp or work cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
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.
5. 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.
6. 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.
7. 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 if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.

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.
WELDING

fire
or
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.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
1. Protect compressed gas cylinders from excessive heat,
mechanical shocks, slag, open flames, sparks, and arcs.
2. Keep cylinders away from any welding or other electrical circuits.
3. Never drape an electrode holder over a gas cylinder.
4. Never allow a welding electrode to touch any cylinder.
5. Never weld on a pressurized cylinder – explosion will result.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
7. 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).
8. 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 and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder when not in use.
11. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
12. Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.

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.”
OM-116 Page 2
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 as
practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
About Pacemakers:
The above procedures are also recommended for pacemaker
wearers. Consult your doctor for complete information.

Miller’s True Blue Limited Warranty shall not apply to:
1.
Consumable components; such as contact tips,
cutting nozzles, contactors, brushes, slip rings,

2.
Items furnished by Miller, but manufactured by others,
such as engines or trade accessories. These items are
covered by the manufacturer’s warranty, if any.
3.
Equipment that has been modified by any party other
than Miller, or equipment that has been improperly
installed, improperly operated or misused based upon
industry standards, or equipment which has not had
reasonable and necessary maintenance, or equipment
which has been used for operation outside of the
specifications for the equipment.
MILLER PRODUCTS ARE INTENDED FOR PURCHASE
AND USE BY COMMERCIAL/INDUSTRIAL USERS AND
PERSONS TRAINED AND EXPERIENCED IN THE USE
AND MAINTENANCE OF WELDING EQUIPMENT.
In the event of a warranty claim covered by this warranty, the
exclusive remedies shall be, at Miller’s option: (1) repair; or (2)
replacement; or, where authorized in writing by Miller in
appropriate cases, (3) the reasonable cost of repair or
replacement at an authorized Miller service station; or (4)
payment of or credit for the purchase price (less reasonable
depreciation based upon actual use) upon return of the goods
at customer’s risk and expense. Miller’s option of repair or
replacement will be F.O.B., Factory at Appleton, Wisconsin, or
F.O.B. at a Miller authorized service facility as determined by
Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.
TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF
PROFIT), WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER LEGAL THEORY.
ANY EXPRESS WARRANTY NOT PROVIDED HEREIN
AND ANY IMPLIED WARRANTY, GUARANTY OR
REPRESENTATION AS TO PERFORMANCE, AND ANY
REMEDY FOR BREACH OF CONTRACT TORT OR ANY
OTHER LEGAL THEORY WHICH, BUT FOR THIS

OPERATION OF LAW, CUSTOM OF TRADE OR COURSE
OF DEALING, INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR
PURPOSE, WITH RESPECT TO ANY AND ALL
EQUIPMENT FURNISHED BY MILLER IS EXCLUDED AND
DISCLAIMED BY MILLER.
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.
