HyDefinition Plasma Cutting solves many problems associated  with conventional plasma. By super constricting the plasma jet, an energy density two or three times that of conventional plasma is produced, resulting in a narrower kerf, squarer edges and less dross.  A sophisticated two stage nozzle produces a more consistent  plasma flow.  The first stage of the nozzle constricts plasma flow like  conventional plasma, but a path is provided to allow excess gas to escape.  Since the pressure gradient at the second stage of the nozzle is more stable , a more consistent plasma stream is realized at the work piece.
