♦
Install and maintain equipment according with local regulations.
♦
Disconnect power supply before performing any service or repairs.
♦
Read and follow all the instructions in the Operating Manual.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the welding arc.
♦
Be sure there is no combustible or flammable material in the workplace. Any material that cannot be
removed must be protected.
♦
Ventilate all flammable or explosive vapours from the workplace.
♦
Do not cut or weld on containers that may have held combustibles.
♦
Provide a fire watch when working in an area where fire hazards may exist.
♦
Hydrogen gas may be formed and trapped under aluminium workpieces when they are cut underwater
or while using a water table.
DO NOT
cut aluminium alloys underwater or on a water table unless
the hydrogen gas can be eliminated or dissipated. Trapped hydrogen gas that is ignited will cause an
explosion.
NOISE
Noise can cause permanent hearing loss. Plasma arc processes can cause noise levels to exceed
safe limits. You must protect your ears from loud noise to prevent permanent loss of hearing.
♦
To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs. Protect others in
the workplace.
♦
Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.
ARC RAYS
Arc Rays can injure your eyes and burn your skin. The welding arc process produces very
bright ultra violet and infra red light. These arc rays will damage your eyes and burn your skin
if you are not properly protected.
♦
To protect your eyes, always wear a welding face shield. Also always wear safety glasses with side
shields, goggles or other protective eye wear.
♦
Wear welding gloves and suitable clothing to protect your skin from the arc rays and sparks.
♦
Keep welding face shield and safety glasses in good condition. Replace lenses when cracked,
chipped or dirty.
♦
Protect others in the work area from the arc rays. Use protective booths, screens or shields.
♦
Use the shade of lens as recommended in this Operating Manual.
