Features & Benefits:
    • TIG:
      - AC and DC output for aluminum and non-ferrous alloys, stainless, mild steel & chrome molys.
      - AC Frequency: Adjustable frequency of the AC square wave when welding on aluminum for optimized set up (15 Hz - 150Hz).
      - Wave Balance: Adjustable for optimized penetration or cleaning action when welding on aluminum.
      - HF Arc Start: Provides non-contact arc starting that eliminates tungsten or material contamination.
      - Lift TIG Start: Provides optimized TIG arc starting without the use of high frequency.
      - Pulse: Changes the weld current from high to low at a specified frequency, reduces heat input on thin material (0.5 Hz - 200 Hz).
      - Preflow & Postflow: Enables independent control over shielding gas before and after the weld.
      - Upslope / Downslope & Crater modes: Eliminates cracking at the end of the weld.
      - Hot Start: Ensures fusion at arc starts for both TIG and Stick processes.
    • STICK:
      - Adjustable Arc Force & Hot Start Control for optimum Stick electrode performance.
    • Other Features:
      - Digital Meters: Voltage and Amperage; Preview and Hold Capability for easy set up
      - Trigger Control: 4T (Latch) eliminates operator fatigue
      - Comprehensive Setup Chart: Weld set up guide for optimum welding performance over a wide range of materials
      - Remote Receptacle: Enables connection of remote control devices like a foot pedal and
      torch slide control
      - Excellent Portability: Lightweight at 48.4 lbs
      - Overload Protection: Shuts down the power source to protect the internal electrical components from overheating
      - IP23S: Suitable for outdoor use.
