- Built with modern inverter technology
 - Ideally suited for assembly work due to protection class IP 21S generally also for outdoor work
 - Universally applicable for welding of all common electrode types
 - TIG pulsing enables welding with reduced heat input
 - HF high frequency ignition ignites during TIG welding without touching the workpiece
 - Quiet running fans dissipate heat well from the equipment for long duty cycles
 - Time controlled fan with stand-by mode
 - Adjustable balance
 - Precise setting of welding parameters via digital display
 - Device equipped with PFC (power factor correction), enables best use even on cable drums
 - Optional with water cooling
 - Multivoltage from 110 to 230 volts 
 - Nine programs can be stored
 - AC triangle wave welding output: reduced heat input for the same current setting, especially useful for welding thin metal
 - AC Sine Wave Welding Output: Traditional AC TIG welding waveform, quieter, "softer" arc characteristics.
 - AC square wave: focused arc for maximum penetration, fast travel speed with best directional control
 - MMA mode with hot-start and arc-force control
 - Adjustable welding curve
