• 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, Publica-
tions.
• Disconnect power source before performing any
service or repairs.
• Read and follow all the instructions in the Operat
-

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 under-
water 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 dis-
sipated. 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 pro
-
tective 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.
• 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 hel
-
met 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:
