Is there a guide to building a 3-phase AC welder?
I was looking through the MANY guides on the web for weldernators and I'm in the midst of putting it together. It suddenly occurred to me that my dad used to own both 5 and 3 phase AC welders and I thought "wait a minute, an alternator is 3 phase AC". I searched and searched but I'm doing a lot of searching on a smartphone because of a really long couple of work weeks, plus I suck at Google apparently. (If I wanted to buy one I could find that.)
Anyway, I'm just not sure of how a 3 phase AC welder works. Maybe it just turns it into DC. They were just arc welders anyway.
