The Cold Wire TIG System works independently of a standard TIG power supply using normal TIG welding parameters. 
The WF5 feed unit is designed for use with the “CWH” series hand torches for semi-automatic welding applications, and “CWM” series machine-mounted torches. 
The WF-5 has an ON/OFF switch, pilot light, pulse/continuous feed switch, pulse wire on and off timers, remote switch receptacle, delay wire start and wire retract.
