zards are shown in the adjoining symbols or explained in

the text.

NOTICE

Indicates special instructions.

Beware of electric shock from the cutting torch or wiring.

Touching the cutting torch while in contact with the work

or ground can cause electric shock. Always wear dry

gloves. Keep all panels and covers closed.

Cutting sparks can cause fire or explosion. Move flam-

mables away. Do not cut on closed tanks or barrels −

they can explode. Clean tanks or barrels properly.

Arc rays can burn eyes and skin − wear face protection

(helmet or face shield) with correct shade of filter, and

cover exposed skin with nonflammable clothing.

Hot parts can cause burns. Cutting makes parts very hot

− let them cool before touching.

Allow cooling period. Reduce current or reduce duty cycle

before starting to cut again. Follow rated duty cycle.

Wear safety glasses with side shields.

Cutting processes cause flying pieces of metal and

sparks. Wear a face shield.

Static electricity can damage parts on circuit boards. Put

on grounded wrist strap before touching circuit board.

Have only trained and qualified persons install, operate,

or service this unit. Call your distributor if you do not un-

derstand the directions. For CUTTING SAFETY and EMF

information, read power source Manual.

Beware of moving parts. Keep guards and panels in

place, covers closed, and hands away from moving parts.

Breathing cutting fumes and gases can harm your health.

Cutting requires good ventilation. If ventilation is impossi-

ble, such as when cutting in a confined space, use an

air-supplied respirator.

The plasma arc can cause injury. The intense heat of the

arc or pilot arc can cause serious burns. Keep away from

the torch tip when the trigger is pressed. Do not grip ma-

terial near the cutting path.

Prolonged noise from some cutting applications can dam-

age hearing. Use approved ear plugs or ear muffs if noise

level is high.

Duty Cycle is percentage of 10

minutes that unit can cut at rated

load without overheating.

NOTICE − Exceeding duty cycle

can damage power source and

torch and void warranty.
