System Components
See Section 3 for details of the system interconnections.
Power Supply
The power supply houses four 100-amp, 15 kHz choppers to produce up to 400A of constant current DC output.
Machine Torch
The maximum production cutting capability of the torch is 1-1/4 inches (32 mm). To achieve consumable long
life, all cuts must begin and end on the plate surface.
Valve Cluster
The valve cluster consists of 5 valves and interfaces with the machine torch, the ignition console and the gas
console. The valve cluster must be located within 4 ft (1.2 m) of the torch and within 50 ft (15.3 m) of the gas
console.
Gas Console
This unit houses metering and solenoid valves, pressure readout LEDs and gas selection switches to choose, set
and monitor plasma and shield gases. The gas console must be located within 50 ft (15.3 m) of the valve cluster.
Ignition Console
The ignition console generates a high voltage, high frequency signal and couples it to the cathode lead and pilot
arc lead. This ignition console must be located within 15 feet (4.6 m) of the torch.
Cooler
This unit circulates a coolant solution to the torch. The cooler interfaces with the ignition console and the power
supply. For more information, see Torch Coolant Requirements in the Installation section of this manual.
Remote Current Control Console - Optional
The remote current control console contains a thumb-wheel switch to set the arc current. If a machine interface will
provide current control for the plasma system, you will not need this console.
Command THC - Optional
The Command THC is an external torch height control and initial height sensing system designed for plasma
cutting applications on an x-y cutting table. Refer to the Command THC instruction manual 802780 for more
detailed information.
