The above reply is very good. If the contactor is buzzing, it will need to be blown out with high pressure air. When I was a welding repair shop manager, we washed every machine out with a pressure washer and then we blew the machine out with high pressure air. When dealing with high electronic machine, you have to avoid getting the electronics wet and high pressure air can damage circuits and wiring. Contractors are easily taken apart and cleaned. WARNING: Any work done on the inside of the machine should only be done with the machine unplugged or locked out. Good luck.

Check main fuses or circuit breaker. Also check plug and cord.

An old welding torch is not exactly valuable and I certainly wouldn't use it unless it is in excellent condition and I didn't have another more modern and much safer model, though if you have the complete kit you certainly have an interesting curiosity. The complete kit comprises the gas mixing handle, the welding stem and a selection of jets or nozzles and usually a cutting stem and at least one cutting nozzle. There is usually a nice box and a set of jet cleaners to complete the set.
