Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I'm new to the forum, and hoping someone in here can help figure out the answer to my dilemma. I'm debating whether to build a new phase converter for a 3 phase welder, or reconfigure my current welder from 230VAC to 460VAC. I know the standard equation for watts is- Watts = Volts x Amps. If I run my current single phase welder off a 460 transformer, I can reduce my amperage by half from 90 amps- maximum AC input, to 45 amps.

In short, am I going to be supplying my transformer with 45 amps as the meter sees it, or 90 amps?

Thanks in advance,

Matt
