Anti-stick prevents the electrode from annealing.
If the electrode sticks in spite of the Arcforce device, the machine
automatically switches over to the minimum current within about 1
second to prevent the electrode from overheating. Check the welding
current setting and correct according to the welding task!
5.11.5 Pulse
welding
Welding characteristics:
• Especially suitable for root welding
• Fine-flaked weld surface with a TIG look for final passes
• Less finishing work thanks to less spatter
• Highly suitable for difficult electrodes
• Outstanding gap bridging with no sagging of the root side
• Less distortion thanks to controlled heat input

AMP = Main current; e.g. 100 A
IPL = Pulse current = IP1 x AMP; e.g. 170% x 100 A = 170 A
IPP = Pulse pause current
Tpuls = Duration of one pulse cycle = 1/FrE; e.g. 1/1 Hz = 1 s
bAL = Balance = bAL x Tpuls; e.g. 30% x 1 s = 0.3 s
The pulse pause current (I2) requires no setting. This value is calculated by the machine control,
so that the welding current average value always corresponds to the main current selected.
