  • Present special advanced Pulse characteristic for AC and DC for welding aluminum and aluminum alloys & carbon steel, stainless, copper and non-ferrous material, increasing travel speed and reduces warping
  • Reliable digital inverter pulse mode AC/DC TIG welding, with HF and MMA (Stick) for constant inverter functioning
  • Adjustable slop up/down, Gas Pre-flow and Post-flow control for maximum shielding gas protection before and after the weld
  • Portable and Lightweight design presents rugged exterior and a flip down visor to protect panel from burns and damage
  • Advanced pulse functions facilitate better control over heat input, resulting less distortion on thin metals
  • Combination of AC and DC TIG permit deep penetration and significantly cut down electrode consumption
  • Self-regulating compensation for mains voltage fluctuations within ±20%
  • 2T/4T up and down slope application for welding with torch switch
  • Micro pulse disparaging heat affected zone especially on thin material
