ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses
and produces high voltage electrical energy. This electric
energy can cause severe or fatal shock to the operator or
others in the workplace.
• Never touch any parts that are electrically “live” or “hot.”
• Wear dry gloves and clothing. Insulate yourself from
the work piece or other parts of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist
or damp.
• Install and maintain equipment according to NEC
code, refer to item 9 in Subsection 1.03, Publications.
• 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 mate-
rial 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 hy-
drogen 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 pro-
cesses 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 protec-
tive ear plugs and/or ear muffs. Protect others in the
workplace.
• Noise levels should be measured to be sure the deci-
bels (sound) do not exceed safe levels.
• For information on how to test for noise, see item 1 in
Subsection 1.03, Publications, in this manual.
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 welding helmet
or 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 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.
• Use the shade of lens as suggested in the following
per ANSI/ASC Z49.1:
Minimum Protective Suggested
Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12
400 - 800* 10 14
* These values apply where the actual arc is
clearly seen. Experience has shown that lighter
filters may be used when the arc is hidden by
the workpiece.
