I think I fried my mig welder

I doubt you "toasted" either the transformer or the reluctor. You would SMELL them, and problaby "let all the smoke out."

yep, just over heated and shut off they do..
especially if you use a long extension cord....they shut off for a minute.


I have the lincoln 125 weld pack, been using it for a year and a half with no issues once I bought a 6 gauge extension cord from harbor freight, thing works really good for what it is.

I can't see buying any lincoln or miller below the Lincoln 125 unit, unless all you ever weld up is wheel barrows.
