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
processes can cause noise levels to exceed safe limits.
You must protect your ears from loud noise to prevent
permanent loss of hearing.

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.

filters may be used when the arc is hidden by
the workpiece.
