SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground.

•Always wear dry insulating gloves.

FUMES AND GASES

can be dangerous.

• Keep your head out of fumes.

•Use ventilation or exhaust to remove fumes from breathing zone.

WELDING, CUTTING and

GOUGING SPARKS

can cause fire or explosion

•Keep flammable material away.

•Do not weld, cut or gouge on containers that have held combustibles.

ARC RAYS can burn.

•Wear eye, ear and body protection.

PLASMA ARC can injure

•Keep your body away from nozzle and plasma arc.

•Operate the pilot arc with caution. The pilot arc is capable of burning the operator, others or even piercing safety clothing.

Observe additional Safety Guidelines detailed in the beginning of this manual.

DESCRIPTION

The Pro-Cut 55 is a constant current, continuous con- trol plasma cutting power source. It provides superior and reliable starting characteristics, cutting visibility and arc stability. When cutting expanded metal, the Pro-Cut 55 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 and 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 55 comes standard with an air regulator, coarse air filter, and pressure gauge. The machine also comes with an 11' input power cord. There are four 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 with each Pro-Cut pur- chase so that cutting can begin right out of the box. Consumables can also be ordered as individual pack- ages. An undercarriage kit can also be ordered sepa- rately.

The Pro-Cut 55 initiates the plasma arc with a simple, yet reliable, touch start mechanism. This system elimi- nates many of the failure problems associated with hi- frequency start systems. The Pro-Cut 55 is capable of cutting with nitrogen or air. Nitrogen is used to cut alu- minum and other nonferrous metals.

The Pro-Cut 55 is controlled by a microprocessor- based control board. The machine performs rudimen- tary self troubleshooting when powered up which aids in field servicing.

PREHEAT TEMPERATURE FOR PLASMA CUTTING

Preheat temperature control is not necessary in most applications when plasma arc cutting or gouging. Preheat temperature control may be necessary on high carbon alloy steels and heat treated aluminum for crack resistance and hardness control. Job conditions, pre- vailing codes, alloy level, and other considerations may also require preheat temperature control. The following minimum preheat temperature is recommended as a starting point. Higher temperatures may be used as required by the job conditions and/or prevailing codes. If cracking or excessive hardness occurs on the cut face, higher preheat temperature may be required. The recommended minimum preheat temperature for plate thickness up to 1/2" (12.7mm) is 70°F (21.1°C).
