    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.


    MIX TIG Frequency (Hz):

    the cycle time of MIX
    TIG in 1 second. Adjustable range: 0.1-10Hz.


    MIX TIG Balance (DC) %:

    DC Balance (%) = (tad/Tmix) x 100


    MIX TIG Frequency (Hz):


    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


    DC TIG-Pulse

    High Speed DC TIG-Pulse Controls
    • PPS Pulses per second (Hz):DC = 0.1 – 5,000 PPS
    • % ON – % Peak Time:5 - 95% (Controls the amount of time during each pulse cycle at the PEAK amperage.)
    • Background Amps:5 – 99% (Sets the low-pulse amperage value as a % of the Peak Amps.)



    Typically from 1 to 10 PPS. Provides a heating and
    cooling effecton the weld puddle and can reduce
    distortion by lowering the average amperage. This
    heating and cooling effect also produces adistinct
    ripple pattern in the weld bead. The relationship
    between pulse frequency and travel speed determines
    the distance between the ripples. Slow pulsing can
    also be coordinated with filler metal addition and
    can increase overall control of the weld puddle.


    In excess of 40 PPS, Pulsed TIG becomes more
    audible than visible—causing increased puddle
    agitation for a better as-welded microstructure.

    Pulsing the weld current at high speeds — between
    a high Peak and a low Background amperage —
    can also constrict and focus the arc.This results in
    maximum arc stability, increased penetration and
    increased travel speeds(Common Range:100–500

    PPS).The Arc-Sharpening effects of high speed
    pulsing are expanded to new dimensions. The ability      
    to pulse at 5,000 PPS further enhances arc stability
    and concentration potential — which is are required.
