Antistick
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!
5.7.5.1 MMA pulsed 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
