Cutmaster 42

Cutmaster 42

The Cutmaster 42 is one of the most affordable, highest quality 120V 1/4" (6 mm) plasma systems on the market. At 230V, the Cutmaster 42 delivers 40A, a recommended cut of 3/8”. As part of the TRUE Series, you can rely on the Cutmaster 42 to cut all day at its recommended cutting capacity and to pack more punch when you need it. The Cutmaster 42 incorporates Vent2Shield ( V2S) technology allowing the use of a considerably smaller compressor (less weight to carry, can be used with 120V) compared to similar 40A units.
