Mig welder power supply

Perhaps you should read my posts through. I said no such thing, I did suggest that some single phase machines will run on 3 phase with no neutral..
That video shows some machines are equally happy with a single phase set up or 3 phase.
However this applies to only a few Mig machines

You did say exactly that several times. Heres one for a kick off

Those current settings for the rods would be very high. Typical settings for 4mm would be 170-180 amp max and 3.2 would be 135 amp max.

And some more...
But of course, not only have you watched a youtube video, but you are also a cyclist, so your knowledge must trump my degree in engineering from Southampton university which included several modules on electrical engineering.

Even what you said in that last post is utter rubbish. If it can run from 3 phase no neutral it is a 3 phase machine end of story.
