All Arc Specialties' Arc6 Welding Systems are precision CNC controlled machines. Arc Specialties uses Delta Tau's Pmac motion controller, precision linear slides and rotary axis, and brushless DC servo motors in all Arc 6 systems. The Pmac Motion Controler also controlls the entire welding process to provide truly automated welding. Arc 6 systems can be configured as either a Plasma Welding System or a TIG Welding System.
