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 260-amp, 150-VDC constant-current supply. It contains the circuitry to ignite a torch, a heat
exchanger and pump to cool the torch. The power supply has a serial interface to provide communication with a CNC
controller.
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 PC 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 may be located up to 1.8 m (6 ft) away from the torch and 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 virtually dross-free cutting capacity of the torch is 32 mm (1.25 in) for HyDefinition cutting. The production pierce
capacity is 32 mm (1.25 in) for mild steel and stainless steel and 25 mm (1 in) for aluminum. The maximum cutting
capability (edge start) is 64 mm (2.5 in) for mild steel and stainless steel and 50 mm (2 in) for aluminum.
