Average value pulse welding

Once the pulse function is activated, the red signal lights for the main current AMP and secondary current
AMP% light up at the same time. Average value pulsing means that the system switches between two
currents periodically, an average current value (AMP), a pulse current (Ipuls), a balance (
quency ( ) having been defined first. The predefined ampere current average value is decisive, the
pulse current (Ipuls) is defined by the
The pulse pause current (IPP) is not set; the machine control calculates the value instead to ensure that
the average value of the welding current (AMP) is maintained. For average value pulsing, the
is the secondary current only, activated with the torch trigger.
