Average value pulse welding

A special feature with average value pulses is that the power source will always maintain the preset aver-
age value. This makes this method especially suitable for welding according to welding procedure specifi-
cations.
To activate average value pulses in conjunction with the metallurgical pulsing variant, the
in the machine configuration menu must be switched to
To activate average value pulses in conjunction with the thermal pulsing variant, the
machine configuration menu must be switched to
Once the function is activated, the red signal lights for the main current AMP and secondary current
AMP% light up at the same time.
Average value pulse welding means that the system switches between two currents periodically, with an
average current value (AMP), a pulse current (Ipuls), a balance (
defined first. The predefined ampere current average value is decisive, and the pulse current (Ipuls) is
defined by the
set in the Expert menu > see 5.3.4 chapter.
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.
AMP = main current (average value), e.g. 100 A
Ipuls = pulse current =
IPP = pulse pause current
Tpuls = duration of one pulse cycle = 1/
= balance

Power-saving mode (Standby)

You can activate the power-saving mode by either pressing the push-button > see 4.3 chapter for a pro-
longed time or by setting a parameter in the machine configuration menu (time-controlled power-saving
mode ) > see 5.9 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.
