ABSTRACT:
A unique torch assembly having specific characteristics determinative of the desired operating parameters of the torch assembly wherein the torch assembly has a connector plug for selectively connecting the torch assembly onto a universal control station for providing electrical power and gas to said torch assembly, which power and gas flow are to match said operating parameters of the torch assembly. The assembly is provided with an identification circuit for identifying unique torch assemblies with the identification circuit having an electrical property unique to said specific characteristics of unique torch assembly and is also provided with an arrangement to interrogate the identification circuit to sense said electrical property of the circuit. In this manner, the torch assembly can be positively identified.
