Once again the shop list comes through.
Great replies all.
I think most of my use will be thin sheet metal so the convenient 30a/110V
will do but an easy shift to the 220 via a pigtail makes all the sense in the
world.

THanks!
Matt

    30 amps of 110v provides 3300 watts.  20a of 220v is 33% more, in other
words, better ;)

    Make a pigtail, so you can plug the machine into either place.  I
seriously doubt you will regret this, unless you really know you'll never
need the top end ( and no friends who will ask you to bring it to their
shop to cut something, etc ).   You are probably not going to get more
than 30a output from your 50a cutter on the 110v circuit.  Speaking of
which, it's doubtful you'll 50a under any circumstances.  50a cutters
normally need around 35a x 220v input, which is nearly double the spec
for this model.
