                                                Description
                                            
- 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
- Adjustable balance
- Quiet running fans ensure good heat dissipation and high duty cycle
- Time controlled fan with stand-by mode
- Precise setting of welding parameters via digital display
- 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
- Exclusively available including factory assembly, part number 9002800
