Read entire Installation Section before installing
the PRO-CUT 60.

SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK CAN KILL.
• Only qualified personnel
should install this machine.
• Turn the input power OFF
at the disconnect switch or
fuse box before working on
the equipment.
• Do not touch electrically hot parts.
• Always connect the PRO-CUT 60 ground-
ing terminal (located on the side of the
Case Back Assembly) to a good electrical
earth ground.
• Turn the PRO-CUT Power Switch OFF
when connecting power cord to input
power.

SELECT PROPER LOCATION

Place the PRO-CUT 60 where clean air can freely
circulate in through the front intake and out
through the rear louvers. Dirt, dust, or any foreign
material that can be drawn into the machine
should be kept at a minimum. Not following these
precautions can result in the nuisance shutdown
of the machine because of excessive operating
temperatures.
The location or improper installation of the
machine could affect the operation of radio, TV, or
electronic equipment. See the HIGH FREQUEN-
CY INTERFERENCE PROTECTION Section for
more information.

STACKING

The PRO-CUT 60 cannot be stacked.
INSTALLATION

TILTING

The PRO-CUT 60 must be placed on a stable,
level surface using the attached undercarriage so
it will not topple over.
HIGH FREQUENCY INTERFERENCE
PROTECTION
Locating, installing, or maintaining the PRO-CUT
60 incorrectly could cause interference with prop-
er radio, TV, or electronic equipment operation
and result in poor cutting and gouging perfor-
mance. The spark gap oscillator in the machine's
high frequency generator generates electrical sig-
nals like a radio transmitter that can cause high
frequency interference. Therefore, properly locat-
ing, installing, and maintaining the machine can
reduce or eliminate the effects of high frequency
interference or the loss of high frequency machine
operating power.
The following procedures should be followed to
minimize interference to the following areas:
• the machine
• the cutting leads
• feedback into the power lines
• ungrounded metallic objects
1. Make the power supply lines as short as
possible.
2. Enclose power supply lines entirely in rigid
metallic conduit (or equivalent shielding)
a. Provide a good electrical ground between
the conduit and the machine.
b. Connect both ends of the conduit to a
driven ground.
c. Entire conduit length should be
continuous.
NOTE: The machine frame must be grounded.
The work terminal ground DOES NOT ground
the machine frame.
