SHOCK HAZARDS

WARNING

ELECTRIC SHOCK CAN KILL!

To reduce

the risk of death or serious injury from shock,

read, understand, and follow the following

safety instructions. In addition, make certain

that anyone else who uses this equipment,

or who is a bystander in the operating area

understands and follows these safety instruc-

tions as well.

IMPORTANT!

TO REDUCE THE RISK

OF DEATH, INJURY, OR PROPERTY

DAMAGE, DO NOT ATTEMPT

OPERATION of this equipment until you

have read and understand the following

safety summary.

• Do not, in any manner, come into

physical contact with any part of the cut-

ting current circuit. The cutting current

circuit includes:

a. the work piece or any conductive

material in contact with it,

b. the ground clamp,

c. the torch,

d. any metal parts on the torch.

• Do not operate in a damp area or come

in contact with a moist or wet surface.

• Do not attempt to operate if any part of

clothing or body is wet.

• Do not allow the equipment to come in

contact with water or moisture.

• Do not drag cables, cutting torch, or

power cord through or allow them to

come into contact with water or moisture.

• Do not touch unit or attempt to turn unit on

or off if any part of the body or clothing is

moist or if you are in physical contact with

water or moisture.

• Do not attempt to plug the unit into the

power source if any part of body or cloth-

ing is moist, or if you are in physical

contact with water or moisture.

• Do not connect ground clamp to or cut on

electrical conduit.

• Do not alter power cord or power cord

plug in any way.

• Do not attempt to plug the unit 

into the power source if the ground prong

on power cord plug is bent over, broken

off, or missing.

• Do not allow the unit to be connected to

the power source or attempt to operate if

the unit, cables, work area, or power cord

are exposed to any form of atmospheric

precipitation, or salt water spray.

• Do not carry coiled cables around shoul-

ders, or any other part of the body, when

they are plugged into the unit.

• Do not modify any wiring, ground 

connections, switches, or fuses in this

equipment.

• Wear welding gloves to help insulate

hands from cutting circuit.

• Keep all liquid containers far enough

away from the unit and work area so that

if spilled, the liquid can not possibly come

in contact with any part of the unit or elec-

trical circuit.

• Replace any cracked or damaged parts

that are insulated or act as 

insulators such as cables, power cord, or

electrode holder IMMEDIATELY.

FLASH HAZARDS

WARNING

ARC RAYS CAN INJURE EYES AND

BURN SKIN!

To reduce the risk of injury

from arc rays, read, understand, and follow

the following safety instructions. In addition,

make certain that anyone else that uses this

equipment, or is a bystander in the work

area understands and follows these safety

instructions as well. Headshields and filter

should conform to ANSI Z87.1 standards.

• Do not look at an electric arc without proper

protection. A cutting arc is extremely bright

and intense and, with inadequate or no eye

protection, the retina can be burned, leav-

ing a permanent dark spot in the field of

vision. A shield or helmet with a number 8

shade filter lens (minimum) must be used.

• Do not strike an arc until all bystanders

and the operator have protective shields

and/or helmets in place.

• Do not wear a cracked or broken 

helmet and replace any cracked or

broken filter lenses IMMEDIATELY.
