  • Internal digital voltage control (DVC) enables operator to preset weld voltage in the CV mode before striking an arc.
  • Process selector switch automatically sets contactor requirements eliminating switches.
  • 15 amp 115 VAC duplex receptacle allows operators the flexibility to run grinders, drills, coolers, etc. from power source.
  • Lift-Arc™ allows TIG starting without the use of high frequency.
  • Line voltage compensation keeps welding parameters constant even when input voltages change ±10%. Eliminates need to change welding parameters throughout the day.
  • Unique Fan-On-Demand™ cooling system operates only when needed. Reduces contaminants drawn into the machine and excess noise in work areas
  • Power efficient for exceptional value and return on your investment.
  • Digital meters monitoring welding voltage or amperage for more precise control.
  • Thermal Overload Protection Internal components are protected from damage by thermal overload protection which automatically shuts down the unit if duty cycle is exceeded or air flow and cooling are restricted.
