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

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.

D Do not use AC output in damp areas, if movement is confined, or if

there is a danger of falling.

D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on

unit.

D Additional safety precautions are required when any of the follow-

ing electrically hazardous conditions are present: in damp
locations or while wearing wet clothing; on metal structures such
as floors, gratings, or scaffolds; when in cramped positions such
as sitting, kneeling, or lying; or when there is a high risk of unavoid­able or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomatic DC constant voltage (wire) welder, 2) a D C manual
(stick) welder, or 3) an AC welder with reduced open-circuit volt­age. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!

D 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).

D Properly install and ground this equipment according to its

Owner’s Manual and national, state, and local codes.

D 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.

D When making input connections, attach proper grounding conduc-

tor first − double-check connections.

D Frequently inspect input power cord for damage or bare wiring −

replace cord immediately if damaged − bare wiring can kill.

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 th e oxygen level causing injury or death. Be sure the breath­ing air is safe.

D Do not weld in locations near degreasing, cleaning, or spraying op-

erations. 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-229 038 Page 1

ARC RAYS can burn eyes and skin.

BUILDUP OF GAS can injure or kill.

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 fil-

ter 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 mate-

rial (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

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.

1-6. EMF Information

Considerations About Welding And The Effects Of Low Frequency
Electric And Ma g netic 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:

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.

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.
