5.4.2 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
parameter
in the machine configuration menu must be switched to
.
To activate average value pulses in conjunction with the thermal pulsing variant, the
parameter in 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 (
) and a frequency (
) having been
defined first. The predefined ampere current average value is decisive, and the pulse current (Ipuls) is
defined by the
parameter as a percentage of the average current value (AMP). The
parameter is
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.
Figure 5-33
AMP = main current (average value), e.g. 100 A
Ipuls = pulse current =
x AMP, e.g. 140% x 100 A = 140 A
IPP = pulse pause current
Tpuls = duration of one pulse cycle = 1/
, e.g. 1/100 Hz = 10 ms
= balance
5.5 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.
