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 work-
place.
• 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 Sub-
section 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 infrared
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 protec-
tive booths, screens or shields.
• Use the shade of lens as suggested in the following per
ANSI/ASC Z49.1:
Arc Current
Less Than 300*
300 - 400*
400 - 800*
*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.
