som _nd_4/98
1-1. Symbol Usage
Means Warning! Watch Out! There are possible
hazards with this procedure! The possible hazards are
shown in the adjoining symbols.
Marks a special safety message.
Means “Note”; not safety related.
This group of symbols means Warning! Watch Out! possible
ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary
actions to avoid the hazards.
1-2. Arc Welding Hazards
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. 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.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the
work or ground.
Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on
unit.
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).
Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
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.
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 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.
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 after removal of
input power on inverters.
Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
FUMES AND GASES can be hazardous.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
If ventilation is poor, use an approved air-supplied respirator.
Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
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.
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.
OM-184 693 Page 2
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.
ARC RAYS can burn eyes and skin.
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).
Wear approved safety glasses with side shields under your
helmet.
Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant
material (leather and wool) and foot protection.
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.
WELDING can cause fire or explosion.
Protect yourself and others from flying sparks and hot metal.
Do not weld where flying sparks can strike flammable material.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
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).
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.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
FLYING METAL can injure eyes.
Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use
approved air-supplied respirator.
HOT PARTS can cause severe burns.
Do not touch hot parts bare handed.
Allow cooling period before working on gun or
torch.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
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.
Wear approved ear protection if noise level is
high.
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.
CYLINDERS can explode if damaged.
Protect compressed gas cylinders from excessive heat,
mechanical shocks, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder – explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.

Keep high-frequency source doors and panels tightly shut,
keep spark gaps at correct setting, and use grounding and
shielding to minimize the possibility of interference.
ARC WELDING can cause interference.
Electromagnetic energy can interfere with
sensitive electronic equipment such as
computers and computer-driven equipment
such as robots.
Be sure all equipment in the welding area is
electromagnetically compatible.
To reduce possible interference, keep weld cables as short as
possible, close together, and down low, such as on the floor.
Locate welding operation 100 meters from any sensitive elec-
tronic equipment.
Be sure this welding machine is installed and grounded
according to this manual.

1-5. 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 electro-
magnetic 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 power-
frequency 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:
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 opera-
tor as practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

TO THE EXTENT PERMITTED BY LAW, THE REMEDIES

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.
