Unique MIX TIG

Everybody knows the AC current has a good clearance and DC current gets a good penetration. What if mix the AC and DC?
MIX TIG is TOPWELL’s unique technology, it contains AC current and DC current in one duty cycle.

That keeps the advantages and reduces disadvantages from each other. Using the MIX TIG technology gets an excellent arc concentration and can be carried out the excellent welding performance, especially for thick plates.

MIX TIG advantage

  • Nice weld appearance, deep penetration.
  • Excellent Arc Concentration.
  • Substantially reduce the electrode consumption.
  • Complete AC Waveshape Controls

    AC Frequency control

    Controls the width of the arc cone. Increasing the AC Frequency provides a more focused arc with increased directional control.

    Note: Decreasing the AC Frequency softens the arc and broadens the weld puddle for a wider weld bead.

    AC Balance Control

    Controls arc cleaning action. Adjusting the % EN of the AC wave controls the width of the etching zone surrounding the weld.

    Note: Set the AC Balance control for adequate arc cleaning action at the sides and in front of the weld puddle. AC Balance should be fine tuned according to how heavy or thick the oxides are.

    Amplitude Control

    Adjusts the ratio of EN to EP amperage to precisely control heat input to the work and the electrode.

    Note: EN amperage controls the level of penetration, while EP amperage dramatically effects the arc cleaning action along with the AC Balance control.
