5.6.10  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 (

) and a frequency (

) having been defined first. The 

predefined ampere current average value is decisive, the pulse current (Ipuls) is defined by the 

 

parameter 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. 

 

Figure 5-12

 

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
