Need help with Miller spot welder. It's a LMSW-52. I bought at auction
while back and don't really have a steady use for it, but sometimes
something comes up and I'll try it. At first it would weld but now I can't
get any heat out of it. The transformer hums but no weld. Any tips on what
to check or look for would be greatly appreciated. Anybody have one of
these?
