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 220 volt, 60Hz, single-
phase alternating current (ac) power source
fused with a 25 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
198 volts ac or greater than 240 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 220 Vac, 60 Hz, single
phase, 25 amp power source.
WIRING
The wires in the input cable of this machine
are colored in accordance with the following
code:
RED: LIVE
BLACK: LIVE
GREEN & YELLOW: GROUND
Connect the input cable to a suitably fused
220Volt/1 Phase electrical supply.
This unit is wired at the factory for 220 Volt,
1 Phase, 60 Hz operation. Check the voltage
at the power supply before connecting to the
power supply.
WARNING: THIS MACHINE MUST BE
GROUNDED.
Note: If connecting the input cable to an
electrical plug, make sure that the plug is
rated for operation with this unit. Follow all
plug manufacturer’s instructions, making
sure that the live wires and the ground wire
are properly connected to the plug.
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.
