HD plasma was an addition that was made for keeping a competitive edge on metal cutting. The Messer MetalMaster 2.0 can handle raw sheet sizes of up to 5 x 10ft and up to 2" thick on mild steel as well as stainless. With a higher speed of cutting than waterjet, this is a great option for clients looking for parts that don't have overly tight tolerances where hardened edges are acceptable. The cost of HD plasma can tend to be favorable on larger quantity projects that fall within the above parameters.
