A fellow offered me a Lincoln square wave TIG welder. About 10-14 yrs old. He replaced all the boards etc..but it still has an Issue. No matter what he does, it always outputs the full 400 amps. Makes it a bit hard to weld thin stock according to him.
Evidently Lincoln sent him all the schematics and diagrams etc, but is not interested in helping him diagnose the problem. He claims he has about $1000 in all new boards so far. He is the original owner and it suddenly started not being adjustable.
Anyone have any idea of what it could be? This machine IS single phase, ac/dc/ stick/tig etc and would be just the ticket for me, but...Im sure not gonna do any horse trading unless its an easy inexpensive fix. Currently he owes me a BIG favor... so ....
He didnt remember the model number but will call me tommorow with the info. Im not familiar enough with such things, let alone not being able to diagnose at board level such a critter.
He did offer to outright give me a Lincoln motor generator tig welder in running condition, but its 3 phase.
Any idea what it could be? I didnt ask, but I assume...assume he checked the pedal, etc. Gunner
