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 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.



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 stability and concentration potential — which is extremely beneficial to automation where maximum travel speeds 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 welds a thing of the past and significantly reduces weld reinforcement. Adjust the hot start current here and the time here.

Arcforce correction (welding characteristics)

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

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 with the adjusted 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 falls in the set down-slope time to the
end-crater current Iend (minimum current).
If the 1st torch trigger is pressed during the down-slope time,
the welding current returns to the
main current AMP set.
• The main current reaches the end-crater current Iend, the arc
extinguishes.
• The set gas post-flow time elapses.

TIG latched operation

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 drops with 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.
