Average value pulse welding

With average value pulsing, two currents are periodically toggled. The user can adjust the welding current
(average current value AMP), pulse current Ipuls (parameter
welding task. The pulse pause current (IPP) is calculated by the machine control, so that the welding cur-
rent average value (AMP) is maintained and shown. This makes this method especially suitable for
welding according to welding procedure specifications.
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
rameter 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/

5.3 Power-saving mode (Standby)
You can activate the power-saving mode by either pressing the push-button > see 4 chapter for a pro-
longed time or by setting a parameter in the machine configuration menu (time-controlled power-saving
mode ) > see 5.6 chapter.
When power-saving mode is activated, the machine displays show the horizontal digit in the
centre of the display only.
Pressing any operating element (e.g. turning a rotary knob) deactivates power-saving mode and the ma-
chine is ready for welding again.
