#99110 - Spot the welder

I'm also guessing this must be 3 Phase primary, as 400 volts wouldn't be single phase?

Might be - some welders I have seen run phase-phase.

I've only had limited experience with welders around a few hundred Amps, have built a couple of rectifiers around 2000 Amps and those transformers were quite big, I can only imagine what your transformer size is going to be!


Spot welders can really push out amps, remember they run into a virtual short circuit, and take a hell of a lot of current to deliver any real power.
