- Built in modern inverter technology 
- Universally applicable for welding all common types of electrodes
- Ideally suited for assembly work due to protection class IP 21S generally also for outdoor work
- Power factor correction PFC for trouble-free use also on cable drum
- TIG pulsing enables welding with reduced heat input
- HF high frequency ignition ignites during TIG welding without touching the workpiece
- Multivoltage from 110 to 230 volts
- Quiet running fans ensure good heat dissipation and high duty cycle
- Time-controlled fan with stand-by mode
- Precise setting and display of welding parameters via LC display
- Adjustable welding curve
- MMA mode with hot-start and arc-force control
Note: PFC is an electrical or electronic circuit that increases the so-called power factor
