INTRODUCTION
The Powermax800 plasma cutting system uses an inverter power supply to provide a smooth DC output
voltage, producing excellent cut and gouge quality on mild steel, stainless steel, aluminum and other
metals. The Powermax800 power supply provides constant-current output variable from 20 to 50 amps,
for optimum performance on all thicknesses of metal up to 1/2 inch (12 mm) thick. At 50 amps, the
Powermax800 can cut metals up to 3/4 inch (20 mm) thick and will sever metals up to 1 inch (25 mm)
thick.
Air is the primary plasma gas, providing low operating cost combined with high-speed performance.
Cylinder air or shop air can be used as long as it is clean, dry and oil-free. When properly set and
maintained, the pressure regulator and gas filter on the power supply ensure that the correct pressure
and flow rate is supplied to the system at the proper quantity and quality. The Powermax800 can also
cut with nitrogen when extended electrode life is a priority.
This instruction manual provides information for the user to set up and operate the system and perform
limited maintenance on the torch and power supply. This manual also provides a detailed list of safety
practices so that the system can be safely operated and maintained. READ THE SAFETY SECTION
(Section 1) FIRST!
The Powermax800 service manual provides higher-level troubleshooting and a more complete parts list.
