I am going to get a hypertherm powermax30 soon.
It can run on 120v ac(reduced power) or 240v ac(full power).
I will use it mostly at work where I can use 240v, but I might need to
use it at full power at home.

If I make up a cord set that has two 120v plugs feeding one 240v
receptacle, and plug each of the 120v plugs into outlets that are on
different legs of the service could I then get 240v at up to 15 amps?
