Mabey, I am not sure it would actually work out to be a problem, just
something to check.
OK, I will keep this in mind. My phase converter is 17.5 HP idler
capacity. When I loaded it with full 200 amps of welder output
(shorted leads), the third leg sagged to about 190 volts.
Sounds like a good plan to me, I trust you'll let us know how it goes.
I already started, the first thing that I am working on is mounting
the SCR modules.
Alas, I know next to nothing about plasma cutting. Never even tried
one. They weren't all that common when I was welding a lot in the
early 70's. I think it is a constant current process with the arc
confined to the torch and not transferred to the workpiece as in
plasma welding, but that is just a foggy memory of something I may
have read 20 years ago. Perhaps you can pick a particular torch and
find out what it needs.
I see. Well... If I connect my secondaries with each pair in series,
wye, it should give me about 208 volts AC to play with. I think that
it would result in about 300 volts OCV and 200 volts welding power.
But first things first, I want to make it work as a welder first to
get the proof of concept.
