SITE SELECTION

Select a clean, dry location with adequate

working space around all components.

The power supply is fan cooled by air flow

through the front and rear panels. This air

flow must not be obstructed. Provide at least

two feet of space in front of and behind the

unit to allow for free flow of air.

POWER SOURCE CONNECTION

POWER REQUIREMENTS

This plasma cutter is designed to operate on

a properly grounded 120 volt, 60Hz, single-

phase alternating current (ac) power source

fused with a 20 amp time delayed fuse or

circuit breaker. It is recommended that a

qualified electrician verify the 

ACTUAL

VOLTAGE

at the receptacle into which the

plasma cutter will be plugged and confirm

that the receptacle is properly fused and

grounded. The use of the proper circuit size

can eliminate nuisance circuit breaker

tripping when working. 

DO NOT OPERATE THIS UNIT

if the

ACTUAL power source voltage is less than

105 volts ac or greater than 132 volts ac.

Contact a qualified electrician if this problem

exists. Improper performance and/or damage

to the plasma cutter will result if operated on

inadequate or excessive power. 

CONNECT TO POWER SOURCE

WARNING

High voltage danger from power source!

Consult a qualified electrician for proper

installation of receptacle at the power source. 

This plasma cutter must be grounded while in

use to protect the operator from electrical

shock. If you are not sure if your outlet is prop-

erly grounded, have it checked by a qualified

electrician. Do not cut off the grounding prong

or alter the plug in any way and do not use

any adapters between the plasma cutter’s

power cord and the power source receptacle.

Make sure the POWER switch is OFF then

connect your plasma cutter’s power cord to a

properly grounded 120 Vac, 60 Hz, single

phase, 20 amp power source.

EXTENSION CORDS

For optimum performance, an extension cord

should not be used unless absolutely neces-

sary. If necessary, care must be taken in

selecting an extension cord appropriate for

use with your specific plasma cutter. 

Select a properly grounded extension cord

that will mate directly with the power source

receptacle and the plasma cutter power cord

without the use of adapters. Make certain

that the extension cord is properly wired and

in good electrical condition.

Extension cords must be a #12 gauge cord

at the smallest. Do not use an extension

cord over 25 ft. in length.

ASSEMBLING THE PLASMA CUTTER

The following procedures describe the

process required to assemble, install, main-

tain, and prepare to work with your new plas-

ma cutter.

UNPACKING THE PLASMA CUTTER
