AMP = Main current; e.g. 100 A

IPL = Pulse current = IP1 x AMP; e.g. 170% x 100 A = 170 A

I2 = 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

For parameter setting, - See 5.7.6 Expert menu (MMA) chapter.

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.
