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
