The Powermax900 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 Powermax900 power supply provides constant-current output variable from 20 to 55 amps, for optimum performance on all thicknesses of metal up to 5/8" (16 mm) thick. At 55 amps, the Powermax900 can also cut metals up to 7/8" (22 mm) thick and will sever metals up to 1-1/8" (29 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 Powermax900 can also cut with nitrogen when extended electrode life is a priority.
