i just purchased a powermaster 256 and after speaking to i think mark then i might have should boght the 250ex. I read somewhere the unit was basically a 250 ex and a 60 amp cutter in 1 unit. When i spoke to the other guy he explained there are alot of features that the 256 does not have from the 250 ex. Did i screw up?

Were is my primary welding stuff. 1/16 to 5/8 aluminum, chromoly steel for roll cages, and sheetmetal. Can this great machine tune down for sheetmetal alminum and steel? Parameters look like it can but i would like to see if it can.
