Features and benefits

    • Reduces the number of beads attached to the base metal, reducing the time of slag removal.
    • Pulsed DC: By optimal waveform for each material we greatly reduce splatter.
    • Wave pulse mode: cycles through the welding current and wire feed spped to control de weld puddle.
    • DC TIG and DC Stick included.
