MMA pulse welding in the vertical up position (PF)
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
Operating
element
Action
Result
Press the push-button until the
PF Pulse signal light illuminates
(pulse arc welding in the vertical up position).
Figure 5-11
AMP = main current
cPL = pulse current correction
I2 = pulse pause current
cFr = frequency correction
cbA = balance correction
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.
For parameter setting, - See 5.7.5 Expert menu (MMA) chapter.
