moving OUT of my shop and back into my garage at home. shop has three
phase. I want to buy a used MIG, but lots of the ones I see are three
phase. anybody here ever run their MIG (or any other three-phase welder,
for that matter) on a "rotary converter setup"?
would running a welder on a rotary converter setup be 'ill-advised'? I
already have a rotary converter rated "max single motor three hp, max
total hp 12 hp", but it's not clear to me how that relates to using it
with a welder...or if it's even 'doable'?
thanks in advance for educating me on this, guys :-)

Welders run fine on rotary converters. You have no motor startup
current to contend with as you would with a motor, and unless its one of
the latest ones that's all electornic it will use just about any power
you feed it, in fact you could just hook up a bank of caps to generate
the third phase on the old ones and not even bother with a rotary
generator.

Please log in for more thread options I have been told (ot done so) that it will work on single phase just derate
the output.

Some will but you have to watch out for anything with three phase fans
in it. Also the contactors and control ckts have to be hooked to the
active phase for them to operate.

I run a TIG off a phase converter.

I am not sure what are its ratings, but for many welders, it does not
sound like it has nearly enough capacity.
For your information, my current phase converter has 17.5 HP of idler
capacity. The previous 10 hp phase converter was straining
considerably when I tried welding at 200 amps.
Making phase converters is easy and inexpensive.
