- TIG (GTAW) process with LIFT arc ignition (Ø1.0 to 3.2 mm)
- Arc gouging with carbon electrodes (up to Ø8 mm)
- Adjustable Hot Start for improved arc ignition
- Adjustable Arc Force for temporary current increase in difficult welding situations
- Antisticking function to reduce electrode sticking risk
- Switchable Voltage Reduction Device (VRD) to lower no-load voltage to 20V for safety in hazardous areas
- High no-load voltage (84V) for good arc dynamic and cellulosic electrode ignition
- Current and voltage display when welding
- Intuitive controls operable while wearing gloves
- Reinforced structure with 2 steel handles
- Optimised cooling with air-tight ventilation corridor to protect electronic components from dust
