switch

im trying to get out of buying a new torch kit one that would have had a built in switch in the handle.
a fella gave me a torch/lead and switch from another simular ampage unit.
also i wanted to run it off a half sized bottle.

Oh, miles away from me. Anyway, firstly the gas solenoid will be 240v & picks it's power up directly within the circuit of the welder. Secondly, the torch is only low voltage so will not power the solenoid, instead being connected in circuit through the PCB.
What's the problem with your old torch? I have replacement brass gas valves in stock, save you buying the complete torch assembly.
