2) Electrode holders

Fully insulated electrode holders should be used. Do NOT use holders with

protruding screws or with any form of damage.

3) Connectors

Fully insulated lock-type connectors should be used to join welding cable.

4) Cables

Frequently inspect cables for wear, cracks and damage. IMMEDIATELY

REPLACE those with excessively worn or damaged insulation to avoid

possibly lethal shock from bared cable. Cables with damaged areas may

be taped to give resistance equivalent to original cable. Keep cable dry,

free of oil and grease, and protected from hot metal and sparks.

5) Terminals and other exposed parts

Terminals and other exposed parts of electrical units should have insulating

covers secured before operation.

6) Electrode

a) Equipment with output on/off control (contactor)

Welding power sources for use with the gas metal arc welding, gas

tungsten arc welding and similar processes normally are equipped with

devices that permit on/off control of the welding power output. When

so equipped the electrode wire becomes electrically LIVE when the

power source switch is ON and welding gun switch is closed. Never

touch the electrode wire or any conducting object in contact with

the electrode circuit unless the welding power source is off.

b) Equipment without output on/off control (no contactor)

Welding power sources used with shielded metal arc welding and similar

processes may not be equipped with welding power output on/off

control devices. With such equipment the electrode is electrically LIVE

when the power switch is turned ON. Never touch the electrode unless

the welding power source is off.

7) Safety devices

Safety devices such as interlocks and circuit breakers should not be

disconnected or shunted out. Before installation, inspection, or service of

equipment, shut OFF all power and remove line fuses (or lock or red-tag

switches) to prevent accidental turning ON of power. Do not open power

circuit or change polarity while welding. If, in an emergency, it must be

disconnected, guard against shock burns, or flash from switch arcing.

Always shut OFF and disconnect all power to equipment. Power disconnect

switch must be available near the welding power source.
