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 instruc-

tions to avoid the hazard. The safety information given be-

low is only a summary of the more complete safety

information found in the Principal Safety Standards listed in

Section 1-5. Read and follow all Safety Standards.

Only qualified persons should install, operate, maintain,

and repair this equipment. A qualified person is defined as

one who, by possession of a recognized degree, certificate,

or professional standing, or who by extensive knowledge,

training and experience, has successfully demonstrated the

ability to solve or resolve problems relating to the subject

matter, the work, or the project and has received safety trai-

ning to recognize and avoid the hazards involved.

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 cir-

cuits are also live when power is on. In semiauto-

matic or automatic wire welding, the wire, wire

reel, drive roll housing, and all metal parts touching

the welding wire are electrically live. Incorrectly in-

stalled 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 weld output in damp, wet, or confined spaces, 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.

� Additional safety precautions are required when any of the follo-

wing electrically hazardous conditions are present: in damp loca-

tions 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 unavoida-

ble 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 DC manual

(stick) welder, or 3) an AC welder with reduced open-circuit vol-

tage. In most situations, use of a DC, constant voltage wire welder

is recommended. And, do not work alone!

This group of symbols means Warning! Watch Out! ELECTRIC

SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult

symbols and related instructions below for necessary actions to

avoid these hazards.

� Disconnect input power or stop engine before installing or servi-

cing this equipment. Lockout/tagout input power according to

OSHA 29 CFR 1910.147 (see Safety Standards).

� Properly install, ground, and operate 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 conduc-

tor first — double-check connections.

� Keep cords dry, free of oil and grease, and protected from hot me-

tal and sparks.

� Frequently inspect input power cord and ground conductor for da-

mage or bare wiring — replace immediately if damaged — bare

wiring can kill.

� Turn off all equipment when not in use.

� Do not use worn, damaged, undersized, or repaired 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.

� Do not touch electrode holders connected to two welding machi-

nes at the same time since double open-circuit voltage will be

present.

� 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. Disconnect cable for process not in

use.

� Use GFCI protection when operating auxiliary equipment in damp

or wet locations.

SIGNIFICANT DC VOLTAGE exists in inverter power sources AF-

TER removal of input power.

� Turn off unit, disconnect input power, and discharge input capaci-

tors according to instructions in Manual before touching any parts.
