Hypertherm HPR400xd

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 highvoltage, 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.
