circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist or damp.
• Disconnect power source 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 plasma 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 vapors 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 aluminum workpieces when they are cut underwater
or while using a water table. DO NOT cut aluminum 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 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.
PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The plasma 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 cutting helmet or shield. Also, always wear safety glasses with
side shields, goggles or other protective eye wear.
• Wear cutting gloves and suitable clothing to protect your skin from the arc rays and sparks.
• Keep helmet 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.
