In a 3-phase spot welder, how are the 3 phases wired to

They aren't.

Carefully.

Seriously I don't know the answer but this sounds like a worthwhile question so here's a bump. Good luck.

wtf is 3 phase jesus what numbnuts came up with this shit like surely just tripling the line frequency would work just fine right?

More level charge through the entire time, less oscillating. Overall a waste but so is a water bed for smooth sleeps.

Well I have a spot welder question.

My company gave my work cell a used spot welder they had.
It's a large unit that's turned wayyyyyy down to make tiny 1mm tacks on F35 parts.

But the damn thing is 10x slower than my current machine.

Takes like 5 seconds for it to go through all the cycles and cooling setting.

How can I speed it up?
