Follow up:
I took the cover off, looks like someone had already (a couple of
screws missing from the cover), and found no signs of any blowed
uppedness. I did find, however a broken off zener diode, which fell out
of the bottom. Maybe that's all that's wrong with it, or not. I guess
I'll sit on it for awhile, if I ever run across someone with 3 phase
460V, I'll replace the diode and see if it works.

Found at dump, Thermal Arc LT-300, brought it home without looking at
it closely. Turns out to be 3 phase 460/565V. I have 3 phase 220v via a
3hp rotary converter. Is there a way to make this all work? I have no
idea if the welder has a fired board or something anyway, but it may be
that the last guy just didn't have 460V either. The cord has been cut
off. Or should I just take it back to the dump?
