    MIX TIG Control

    Features of MIX TIG:

    The AC current can get a very good clearance, and
    DC current can get a deeper penetration. Use the
    MIX TIG we can get an excellent Arc Concentration,
    can be carried out the excellent welding performance
    from thin to thick plate.
    1) Nice weld appearance, deep penetration.
    2) Excellet Arc Concentration..
    3) Substantially reduce the electrode consumption.

    AC Frequency control Controls the
    width of theControls 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 th eoxides are.

    Independent AC Amperage Control
    Allows the EN and EP amperage
    values to beset independently.
    Adjusts the ratio of EN to EP
    amperage to precisely control heat
    EN amperage controls the level of
    penetration, while EP amperage
    dramatically effects the arc cleaning
    action along with the AC Balance
    control.
