HPR400XD Auto Gas – 806160 2-3
System description
General
HyPerformance plasma systems are designed to cut a wide range of thicknesses of mild steel, stainless steel and
aluminum.
Power supply
The power supply is a 400-amp, 200-VDC constant-current supply. It contains the circuitry to ignite a torch. The power
supply has a serial interface to provide communication with a CNC controller.
Cooler
The cooler contains a heat exchanger and pump that reduces the temperature of the coolant that flows to the torch. It
also contains flow and temperature sensors that ensure the cooling system is working properly.
Ignition console
The ignition console uses a spark-gap assembly. The ignition console converts 120 VAC control voltage from the power
supply into high-frequency and high-voltage pulses (9-10 kV) to break over the torch electrode-nozzle gap. The high-
voltage, high-frequency signal is coupled to the cathode lead and pilot arc lead.
Selection console
The selection console manages the selection and mixing of the plasma gases. It contains motor valves, solenoid valves
and pressure transducers. It also contains a control board, an AC relay board and a power distribution board. The
selection console has an LED lamp that illuminates when power is supplied to the system.
Metering console
The metering console controls the flow rate of the gases to the torch in real time. It also controls the gas portion of
the LongLife
®
process. The metering console contains proportional control valves, a PC control board and a power
distribution board.
Torch
The dross-free cutting capacity of the torch is 40 mm (1.5 in) for HyDefinition cutting. The production pierce capacity is
50 mm (2 in) for mild steel, 45 mm (1.75 in) for stainless steel, and 40 mm (1.5 in) for aluminum. The maximum cutting
capability (edge start) is 80 mm (3 in) for mild steel, stainless steel, and aluminum.
