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.
Gas console
The power switch located on the gas console is the main power switch for the system. Power may be present at all
other components when it is in the ON (l) position. The gas console manages the selection and flow rate of all incoming
gases. The gas console includes motor valves, solenoid valves, check valves and pressure transducers. The gas console
also houses a relay PC board and a control PC board.
Off-valve
The off-valve consists of 5 solenoid valves, a manifold block and a wiring harness with connector. The assembly
interfaces with the machine torch, the ignition console and the gas console.
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.
