We used to have a wall of Miller 3ph welders. Done drooling ? Good.
They used an output inductor as well. I am thinking that a stuck rod would've blown a capacitor to bits.
Any good size xfmr should work. Tape off the input leads. Tie one output lead to the + from the rectifier. Tie the other output lead to the ground clamp wire. Tie the - from the rectifier to your stinger and your ready to burn some 7018++
(Yes, most rods run with + ground)
