Thanks greenbuggy, I haven't picked up the welder yet, but it will be free except missing the gun & reg. Is the prime contactor the on/off switch or? Diodes I can check.
Primary contactor is either a relay (or more likely, a solid state relay) that connects input power to the primary (high voltage, low amp) side of the welding transformer.
Without a gun you can test what happens by jumping the 2 contacts that the guns trigger would have connected to, on lots of machines this is connected with a couple of spade terminals.
From there - do your drive wheels turn?
get a DMM and a wiring diagram. Do you have 16-30VDC between the ground clamp and the lug where the gun connects to? The answers to these questions will better help us fix your machine. Maybe if you are lucky a member closer to Spokane will be able to give you a hand or spend some time helping you troubleshoot your machine. Unless you want to buy me a plane ticket. Been a while since I've been to Washington. I love Seattle.
Cons for repairing this machine.
A free welder would be one that is complete and in working condition.
You get what you put into it, and baby you get what you deserve :nono:
Free is never free, the height of naivete would be to assume so. But "cheaply repaired" beats the hell out of "expensive". $150 for a gun and $60 for a regulator would assume you aren't resourceful enough to use the power of eBay/CL to get what you need. I think $150 could get a person a very nice Abicor gun, regulator and an adapter to stick it on his obscure machine. (Go on, ask me how I know)
