We always went by the 75% calculation, but I like that 125% rule too...gives you a little extra to play with.

Re: 230 single phase
Jesus Christ, everybody is an electrician. 
I can go through and disagree with at least one thing everybody said, but who the ---- am I?
My horseshit input:
A 20 amp 2 pole breaker is just that, a 20amp 2 pole breaker. Yes, you can pull ~20amps through each of them without tripping the breaker to total ~40amps, but it's still a 20amp breaker and NOT a 40amp. A 40amp 2 pole breaker is NOT 2 20amp breakers tied together. :1 If it were, wouldn't that make it the same exact rating as a 2 pole 20amp breaker under that idea?
I don't know ---- about welders, but 99.9% of the welders I wire for are ~40amp welders using a 3wire(2 hots, neutral, and a ground) 8ga. wire and usually uses a range plug, Leviton part#279.

Re: 230 single phase
Negative. A "twin" is a breaker that feeds 2 circuits from the same phase. A "2-pole" is a breaker that feeds 1 or 2 circuits from seperate phases. :P

I'm pretty much officially retired as an electrician now...I'd be happy as ---- if I never have to do any of this ever again...government sat/com ftw!
