GENERAL DESCRIPTION
The PRO-CUT 80 is an inverter based constant cur-
rent, continuous control plasma cutting power source.
It provides superior and reliable starting characteris-
tics, cutting visibility and arc stability. When cutting
expanded metal, the PRO-CUT 80 out-performs the
competition due to its quick, clean response to arc
transfers. The power supply design provides high
transfer-to-cut distances, which makes pierce cutting
more reliable with less nozzle wear. The control system
has a safety mechanism to insure that the nozzle and
electrode are in place before cutting or gouging. This
is extremely important due to the high voltages
involved.
The PRO-CUT 80 comes standard with an air regula-
tor, coarse air filter, and pressure gauge. There are six
different torch and cable systems to choose from:
hand-held torch with 25’ or 50’ cable, machine and
robotic torch both with 25’ and 50’ cable.
Consumables are included so that cutting can begin
right out of the box. Consumables can also be
ordered as individual packages.
The PRO-CUT 80 initiates the plasma arc with a sim-
ple, yet reliable, touch-start mechanism. This system
eliminates many of the failure problems associated
with hi-frequency start systems. The PRO-CUT 80 is
capable of cutting with nitrogen or air.
The PRO-CUT 80 is controlled by a microprocessor-
based control board. The machine performs rudimen-
tary self troubleshooting when powered up, which aids
in field servicing.
RECOMMENDED PROCESSES AND
EQUIPMENT
The PRO-CUT 80 is capable of all cutting and gouging
applications within its output capacity of 35 to 85
amps. These applications include thin gage sheet
metal and expanded metal.
OPERATIONAL FEATURES AND
CONTROLS
The PRO-CUT 80 comes with an ON/OFF POWER
SWITCH, OUTPUT CURRENT CONTROL, PURGE
BUTTON, STATUS INDICATORS and a SAFETY
RESET BUTTON. See Figure B.2 and related discus-
sion.
DESIGN FEATURES AND
ADVANTAGES
The microprocessor controlled PRO-CUT 80 design
makes plasma cutting and gouging tasks uncompli-
cated. This list of design features and advantages will
help you understand the machine's total capabilities
so that you can get maximum use from your machine.
• Light weight and portable design for industrial use.
• Continuous control, 35 - 85 amps.
• Reliable touch start mechanism for plasma arc initi-
ation.
• Unique microprocessor controlled starting
sequence for safe and consistent starting.
• Rapid arc transfer for fast cutting of expanded
metal.
• High transfer distance for ease of use.
• Input overvoltage protection.
• 3.0 second pilot arc.
• Purge momentary push button.
• Air regulator and pressure gauge located on the
front of machine for convenience.
• ”Parts-in-Place” mechanism to detect proper instal-
lation of consumables and torch.
• Automatic detection of faulty output control.
• In-line coarse air filter.
