This question is for one of you Electric guys. I have 220 in my shop, I know someone with several 3 phase wire welders that can be had cheap probably. ( he bought out a business ) Knowing nothing about nothing what does one need to know about his wiring and the welders to determine what phase converter to go with if i can do such a thing.? Thanks for any advise or input.
will need rotary phase converter. a few hundred bucks.
That the ones that look like a electric motor with no shaft?
Yes. Rotary has less amperage loss so a little more$. Priced by size motor it is driving.
