GENERAL INFORMATION

Manual 0-5335

• 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-

ing 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 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:

Minimum Protective

Suggested

Arc Current

Shade No.

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.
