USER RESPONSIBILITY

Because design, fabrication, erection and cutting vari- ables affect the results obtained in applying this type of information, the serviceability of a product or struc- ture is the responsibility of the user. Variation such as plate chemistry, plate surface condition (oil, scale), plate thickness, preheat, quench, gas type, gas flow rate and equipment may produce results different than those expected. Some adjustments to procedures may be necessary to compensate for unique individ- ual conditions. Test all procedures duplicating actual field conditions.

RECOMMENDED PROCESSES AND EQUIPMENT

The PRO-CUT 55 is capable of all cutting and goug- ing applications within its output capacity of 25 to 60 amps. These applications include thin gage sheet metal and expanded metal.

OPERATIONAL FEATURES AND CONTROLS

The PRO-CUT 55 comes with an ON/OFF POWER SWITCH, OUTPUT CURRENT CONTROL, PURGE BUTTON and a SAFETY RESET BUTTON.

DESIGN FEATURES AND

ADVANTAGES

The microprocessor controlled PRO-CUT 55 design makes plasma cutting and gouging tasks uncomplicat- ed. 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, 25 - 60 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.

-Soft start of input filter capacitors at start up.

-Input over voltage protection.

-Bright 3.0 second timed pilot arc.

-Purge momentary push button.

-Air regulator and pressure gage located on the front of machine for convenience.

-Parts-in-Place mechanism to detect proper installa- tion of consumables and torch.

-Latching Parts-in-Place mechanism. Requires a positive operator reset.

-Automatic detection of faulty output control.

-In line coarse air filter.

-Preflow/Postflow timing. Preflow is eliminated if arc is re-initiated in Postflow.

-Thermostatic Protection.

-Solid state over-current protection.

-Works with pure nitrogen for cutting nonferrous materials.

-Reconnectable for multiple input voltages.

-Quick disconnect torch.

-Dead front display for machine status.

-Unique electrode and Vortech™ nozzle design for optimum cooling and long life.

-Swirl texture inside Vortech™ nozzle for better start- ing reliability and higher quality cuts.

-Unique drag cup design for durability and elimina- tion of double arcing.
