INTRODUCTION TO CNC Plasma Arc Cutting

Sep 09, 2020 · Plasma arc welding is an arc welding process using heat produced by a compressed arc between a tungsten non-consumable electrode and another workpiece (transferred arc process) or water-cooled constricting nozzle (non-transferred arc process). The plasma is a gaseous mixture of positive ions, electrons, and neutral gas molecules.
