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

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.
