• Install and maintain equipment according to
NEC code, refer to item 4 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 arc weld.
• 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. Arc
welding/cutting 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.
• For information on how to test for noise, see
item 1 in Subsection 1.03, Publications, in
this manual.
ARC WELDING RAYS
Arc Welding/Cutting Rays can injure your eyes
and burn your skin. The arc welding/cutting
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 recommended in
Subsection 1.03, item 4.
