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 & other Exposed parts

Terminals and other exposed parts of electrical units should have insulating covers secured
before operation.

Electrodes

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 hat 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.

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.

Safety Precautions for ARC/TIG Welding

ALWAYS ensure that there is full free air circulating around the outer casing of the machine, and
that the louvres are unobstructed.

1

Welding arc can seriously damage your eyes. Both operator and spectators must ALWAYS
use a proper welding face shield or helmet, with suitable filter lenses. Proper gloves and
working clothes should be worn at all times.

2

ALWAYS check that the pressure regulator and gauges are working correctly.  DO NOT
lubricate the regulator.

3

ALWAYS use the correct regulator. Each regulator is designed to be used with a specific
gas.

4

ALWAYS inspect the hose before use to ensure it is in good condition.
