Welder repair (Miller Trailblazer Pro 350D)

I recently bought a Miller Trailblazer Pro 350D with a Kubota dieseland 714 hours, along with other items that I bought together as a lot. I brought it home, I noticed a tag on the welder saying"BROKE". While a disappointment, I reasoned that 1) the seller, a demolition man, was not aware of this tag, as hewould either remove it if he was dishonest, or tell me about it if he washonest. 2) The welder likely was not worked on, as the tag would have beenmore specific if someone looked at it more closely. What was going on with it is that it would start and run great, butwould produce no output, AC or welding current. A bit of diagnostics with a multimeter, and staying on the millerforum and calling Miller, all pointed to a bad circuit board. I took abit of risk and bought a replacement from Miller for $500 plus tax.The result is great, the welder, now, runs great and welds prettygood. Apparently, that board was poorly designed, and dies for spuriousreasons, like when someone tries to jump start a dead battery. i

Tell me where gunner.

The one source I found for an SP150, not mine, a buddy's; the sobs never returned my calls. BUT the board appears to have been tested out and the "usual screw-up" components were stripped of whatever coating Lincoln uses. (by a Linclon dealer) (yeah) The actual complete board "isn't available any more" /end quote.

An IC and one or two others (items) where cleaned and probably just need the parts sussed out on the interwebs. I, me, sort of offered to find someone to fix it. I can solder it's just I prefer plumbing. ;)

But now that I think of it, he said he wanted it FIXED, two years ago, so I could charge him what I want. -shrug-
