Michael asked: All that said, anyone need an 800 lb. 300A Harnischfeger P&H
3-phase
job-shop DC TIG machine with built-in solenoids and high-frequency
generator? I used it for years until the company for which I worked went
bust and I inherited the welder.... Have been hauling it around for ten
years and have never had 3-phase power available to run it. A real
beast. When I called the company that bought out the factory, a few
years ago, to ask them about any means of converting it to single-phase,
even with lower output, they said, "nope, don't know of any way to do
it, but, hey, they're a real workhorse, aren't they? They stopped
building them in 1954, and we're still using them on the production
floor to build new welders."
The thing belongs in a museum somewhere, I think, as a testament to what
American engineering and production once could do.
Michael-
I ran a big industrial three phase Miller welder in my shop using a rotary
phase converter. The good ones put out power that has characteristics that
work fine in welders (at least it did for me!)
Otherwise, I'll take the P&H welder off your hands!
