I recently bought a Miller Trailblazer Pro 350D with a Kubota diesel
and 714 hours, along with other items that I bought together as a lot.
http://yabe.chudov.com/Miller-Trailblazer-Pro-350D-with-Kubota-Engine-740-hours-2421/2421-0001.jpg
After 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 he
would either remove it if he was dishonest, or tell me about it if he was
honest.
2) The welder likely was not worked on, as the tag would have been
more specific if someone looked at it more closely.
What was going on with it is that it would start and run great, but
would produce no output, AC or welding current.
A bit of diagnostics with a multimeter, and staying on the miller
forum and calling Miller, all pointed to a bad circuit board. I took a
bit of risk and bought a replacement from Miller for $500 plus tax.
The result is great, the welder, now, runs great and welds pretty
good.
Apparently, that board was poorly designed, and dies for spurious
reasons, like when someone tries to jump start a dead battery.

interested in what's on the board and how repairable they might be.

Wow, I'd be looking for a way to isolate that board.

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-
