I work for a welding company and am working on a ship that only has 440v 3-phase power. My welding machine requires 220v single-phase 50A. I assume the only way to do this is with a transformer. If there is a cheaper way I would like to go that route. If not I would like to know what type of transformer to buy and how to wire it up.
Dick there are two diff kinds of 3-phase, one w/ central com and one without. The one with a com should give ya 3 x 220 v . However, 50 amp is quite a load and so you should first check with your Cap
