I've thought about, sometime in the future, adding an AC/DC stick welder
(probably the ubiquitous Lincoln 225A "tombstone") and would like to plan
for it. The problem is that the data sheet on the Lincoln website only
tells you the power requirement is 220v, 60 Hz, single phase. Nary a word
about the current requirement.

Assuming max voltage is around 40 or volts at the stinger, I'd say 50 amps
will do it.
