System description

general

HyPerformance plasma systems are designed to cut a wide range of thicknesses of mild steel, stainless steel
and aluminum.

Power supplies

Each power supply is a 400-amp, 200-VDC constant-current supply. Each contains the circuitry to ignite a torch.
The power supplies have a serial interface to provide communication with a CNC controller.

chiller

The chiller 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.

chiller interface console

The chiller interface console controls the coolant flow through the chiller and out to the torch. It monitors the coolant

temperature, and flow rate, and filters the coolant returning from the torch.

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 mild steel HyDefinition cutting.
The production pierce capacity is 50 mm (2.0 in) for mild steel and 75 mm (3.0 in) for stainless steel and aluminum.
The maximum severance capability (edge start) is 80 mm (3.2 in) for mild steel and 160 mm (6.3 in) for stainless steel

and aluminum.
