Ran across a Big40G locally but it has no power or weld output. Is there anything common in these machines that fails. I have not looked at wiring schematics yet.
Reply:I had a Big Blue 400D, one day same thing. It was a Slo Blow fuse and very hard to find. I'd call Miller's customer service. They'll usually walk you thru it over the phone.It seemed like a good idea at the time!
