Thanks, that's very interesting. Also is this R2D2 any kind of contender for the title "Cadillac of Welders"?
Copied from "7A749" on WW:
"The amount of current needed to turn the motor that spins the generator in that welder is considerable, and that motor would be impossibly large with huge capacitors if it were single phase. It simply wouldn't be efficient at the size and current input requirements needed to operate it. Three phase motors do not need start capacitors and are far more efficient as far as size to current input requirements go."
This says a lot. But there is a big box on the front that could have start capacitors inside ( ? ).
In any case, the singlephase plug looks like it was used, a LOT.
Makes sense that the output of this welder is simply whatever is transmitted thru that motor shaft, ie whatever power the motor can produce. What if the welder was simply unable to output full capacity on singlephase, could it weld @ 200A? (Note: sitting in the rod holder tubes are some 3/16" rods).
