PROTECTION AGAINST SHOCK

Keep your body and clothing dry. Never work in damp area without

adequate insulation against electric shock. Stay on a dry duckboard or rubber

mat when dampness or sweat can not be avoided. Sweat, sea water, or

moisture between body and an electrically LIVE part - or earthed metal -

reduces the body surface electrical resistance, enabling dangerous and

possibly lethal currents to flow through the body.

EARTHING THE EQUIPMENT

When arc welding equipment is earthed according to the National Electrical

Code and the workpiece is earthed, a voltage may exist between the

electrode and any conducting object.

Examples of conducting objects include, but are not limited to, buildings,

electrical tools, work benches, welding power source cases, workpieces, etc.

Never touch the electrode and any metal object unless the welding power

source is off. When installing, connect the frames of each unit such as welding

power source, control, work table, and water circulator to the building earth.

Conductors must be adequate to carry earth currents safely. Equipment

made electrically LIVE by stray current may shock, possibly fatally. Do not

EARTH to electrical conduit, or to a pipe carrying ANY gas or a flammable

liquid such as oil or fuel.

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.

TERMINALS AND OTHER EXPOSED PARTS

Terminals and other exposed parts of electrical units should have insulating

covers secured before operation.

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. A power disconnect switch

must be available near the welding power source.
