    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.)

    CONVENTIONAL PULSED TIG

    HIGH SPEED PULSED TIG

    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.

    MASTER-TIG-350CT-400CT-500CT-▏TIG-Welders_0_35

    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.







    Hot Start

    Hot start function reliably ignites the electrode and melts
    perfectly to ensure the best quality even at the start of
    the seam. This solution makes lack of fusion and cold weldsa thing of the past and significantly reduces weld reinforcement.
    Adjust the hot start current here and the time here.

    Arcforce correction (welding characteristics)

    PROTIG-200Di-250Di-▏TIG-Welders_11

    During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in current.
    This makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular.


    2T/4T

    Non-latched mode

    PROTIG-350CT-400CT-500CT-▏TIG-Welders_07

    1st cycle:
    • Press and hold torch trigger 1.
    • The gas pre-flow time elapses.
    • HF ignition pulses jump from the electrode to the workpiece,the arc ignites.
    • The welding current flows and immediately assumes the value set for the ignition current Istart.
    • HF is switched off.
    • The welding current increases in the set up-slope time to the main current AMP.
    Switching from main current AMP to secondary current AMP%:
    Press torch trigger 2 or Tap torch trigger 1
    2nd cycle:
    • Release torch trigger 1.
    • The main current decreases in the set down-slope time to the end-crater current Iend (minimum current).
    If torch trigger 1 is pressed during the down-slope time,
    the welding current increases again to the set main current AMP.
    • The main current reaches the end-crater current Iend, the arc extinguishes.
    • The set gas post-flow time elapses.


    Latched mode

    PROTIG-350CT-400CT-500CT-▏TIG-Welders_10

    Step 1
    • Press torch trigger 1, the gas pre-flow time elapses.
    • HF ignition pulses jump from the electrode to the workpiece, the arc ignites.
    • Welding current flows and immediately assumes the ignition current value set
     (search arc at minimum setting). HF is switched off.
    Step 2
    • Release torch trigger 1.
    • The welding current increases with the set up-slope time to the main current AMP.
    Switching from main current AMP to secondary current AMP%:
    Press torch trigger 2 or Tap torch trigger 1
    Step 3
    • Press torch trigger 1.
    • The main current decreases in the set down-slope time to the end-crater current Iend (minimum current).
    Step 4
    • Release torch trigger 1, the arc extinguishes.
    • The set gas post-flow time begins.
    Immediate termination of the welding process in the downslope by releasing torch trigger 1.
