Lincoln Electric is excited to introduce you to Tomahawk--our new line of plasma cutters. The Tomahawk 375 Air and the Tomahawk 625 arrive ready to go for fast and precise cutting. The 375 Air cuts 3/8 in. thick steel at 14 ipm and the 625 cuts 5/8 in. thickness at 12 ipm. Both are engine drive compatible and the 375 Air can be used with its internal air compressor for ultimate portability.
