    PULSED TIG

    Conventional Pulsed TIG

    Typically from 0.2 to 10 PPS. Provides a heating and cooling effect on the weld puddle and can reduce distortion by lowering the average amperage. This heating and cooling effect also produces a distinct 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.

    High Speed Pulsed TIG

    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.

    AC waveshape

    Standard Square Wave

    The Standard Square Wave offers fast transitions between EN and EP for a responsive, dynamic, and focused arc with better directional control. It forms a fast-freezing puddle with deep penetration and fast travel speeds.

    Sine Wave

    The Sine Wave a soft arc with the feel of a conventional power source. It provides good wetting action and actually sounds quieter than other waves. Its fast transition through the zero amperage point also eliminates the need for continuous high frequency.

    CUTTING CAPACITY

    Capacity Cutting Cut speed
    Recommended 10mm 500mm/min
      15mm 250mm/min
    Severance(hand cutting) 18mm 125mm/min

    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

    AC Waveshape Controls

    Frequency control

    Controls the width of the 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.

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