Just for interest arising from another group, what sort of welder would
require 150amps at 240? And also assuming no 3 phase supply?

A very big one.

A bloody big!! one!....

Sure you don't mean its got a 150 amp output and doesn't need 150 from
the mains?...

That was my assumption. But the OP says no.

Most arc welders have a working tip voltage of 20V. Say open circuit 50V.
That's a minimum of 600A at the tip - maybe more. There's no way this would
be practical on a single phase and it would be a 3 phase unit. For
large/deep welding this sort of amperage may be required. Never seen one
though.

Just MAYBE an industrial welder from a car factory, although I'd have
assumed these beasts were designed for 415 3ph. Is it possible (having
read your response about the OP insisting it says 150A @ 240v) that it
says 15.0 A peak, and the decimal point wore off?

More likely to be 3ph spot welder rated @ 3x50 amps [1], otherwise I
suspect we are talking railway workshop or ship-yard style
welders....!

[1] and will probably also require either a compressed air supply or
come with
some form of water cooling.....

Well I have a 220amp stick welder running on single phase 240v and its rated
input current at full power (a 4mm rod) is 28amps.

So, a *very* large one!

US? 220V 150A?
