SPECIFICATIONS
Straight Torch Quick Disconnect Assembly
The torch quick disconnect assembly allows mechanized changing of torches by the cutting machine. Inputs from
the RHF console using the torch lead set are: electrode cooling water supply and return, power, and pilot arc.
Inputs from the off-valve assembly are for torch blow back and plasma and shield gases.
Off-Valve Assemblies
Two off-valve assemblies are offered: one with a blow back solenoid valve and the other without a blow back
solenoid valve. Both off-valve assemblies provide on/off control between the preflow and operate gas flows. This
assembly consists of three solenoid valves which provide inlet and outlet gas connections. The inlet connections
(plasma gas, shield gas and preflow gas) are input from the gas console using the gas lead set. The outlet
connections (blow back [if desired], plasma gas and shield gas) are output to the torch quick disconnect assembly.
Optional Units
Timer-Counter
The timer/counter allows the operator to monitor the number of arc starts, the cumulative time that the arc is on in
hours, and the number of arc blow outs. The arc starts and arc errors LCD counters can be reset. This unit
connects with the power supply.
Refer to Appendix D for installation, operation and parts information.
Remote Current Control (RCC)
The RCC allows the operator the ability to select the cutting current from a remote location. This unit connects with
the power supply. Refer to Appendix E for installation, operation and parts information.
