Kevin,

I run two 120 volt ganged variacs.  They are fed by a USA standard 240 volt
circuit (120-neutral-120 volt).  One variac connects between one of the 120
volt feeds and neutral.  The other one connects to the other 120 volt feed
and neutral.  You can get 0 to 240 volts between the two wipers.

(David Rieben gave another response, but I don't see how his scheme could
work.  Depending on which wiper to common you pick, you will end up with 0
to 120 out, or 120 to 240 out, but not 0 to 240.)
