Pulse welding

5.2.7

Average value pulse welding

Average value pulse welding means that two currents are switched periodically, a current average value
(AMP), a pulse current (Ipuls), a balance (
predefined ampere current average value is decisive, the pulse current (Ipuls) is defined by the
meter as a percentage of the current average value (AMP). The pulse pause current (IPP) requires no
setting. This value is calculated by the machine control, so that the welding current average value (AMP)
is maintained at all times.
AMP = Main current; e.g. 100 A
Ipuls = Pulse current =
IPP = Pulse pause current
Tpuls = Duration of one pulse cycle = 1/
= Balance

Arc length restriction (USP)

The arc length restriction
tected (unusually large gap between electrode and workpiece). The function can be switched on or off
depending on the process > see 5.9 chapter.

Signal light of Favourite status
---------- Signal light is green: Favourite loaded, settings of the Favourite and the cur-
rent device settings are identical
---------- Signal light is red: Favourite loaded, but settings of the Favourite and the cur-
rent device settings are not identical (for example, the operating point has
been changed)
