Miller Bobcat 225 resurrection

[Shran]

I got tasked with resurrecting a Miller Bobcat 225 for my buddy. It belonged to his late dad and has been sitting for probably 20 years or more in a barn in south Texas...so it wasn't exactly outside but it's so humid there that the bottom of it is pretty rusty. I think it ran when parked... or something like that... nobody used it so it sat and deteriorated.

I can handle getting the engine running, that is no problem, but the welder/generator part is a bit more of a concern to me. Besides cleaning it out is there anything I need to look at? When I was messing with an old Onan last year there were a lot of people who said that the brushes needed to be cleaned up, commutator polished, etc or it would burn up stuff from the added resistance. Truth to that? Anything else I need to be aware of?

I don’t know how much feedback you’ll get here, not in an expert myself anyway.

Should check out weldingweb.com

it’s a real solid welding related forum.

Welder glues metal together (or apart)

Sorry. That's all I have.

I'm curious as I've run across those things looking somewhat rough before for reasonable cash...

I'm pretty sure they're pretty rustic, transformer welders that likely don't have the fanciest of voltage stability circuitry...

Thanks, I will try over at Welding Web. I forgot about that place.

He dropped it off at my house last Thursday. Maybe it's not as bad as I thought. Apparently it was used "a few" years ago to build some pipe fence so it may not have sat as long as I thought it did. It'll still need some work for sure but 5 or 10 years is not 20.
