  • Advanced squarewave arc for improved weldability on aluminum and magnesium using low power - continuous high-frequency is NOT needed because of the advanced squarewave arc
  • AC frequency control range of 20 - 250 Hz provides control for a focused arc, resulting in better directional control to help produce desired arc/weld bead characteristics
  • Auto-Line™ provides state-of-the-art flexibility by automatically connecting to 120-460 VAC, single- or three-phase power without removing the covers to relink the power source
  • Low OCV Stick is a simple design that reduces open-circuit voltage to 5-10 VDC when the power source is not in use. This built-in circuit design eliminates the need for add-on voltage reducers
  • Inverter-based, AC/DC power source has state-of-the-art operator interface allowing the user extra set-up capabilities in a compact machine


  • Petro/chemical fabrication
  • Aerospace
  • Mechanical contractors
  • Shipboard installation/repair
