Diagnosis
1.7.1 Duo Pulse
A second weld parameter set is generated from the set basic value by
means of the Duo Pulse (Aluplus) function. This can be greater or less than
the basic value. By means of a defined frequency there is a switch-over
between the two parameter sets. The appearance of the weld seam surface
is formed by the defined change of parameters. During root welding,
defined cool-down times are reached depending on the setting.
If the "Duo Pulse" function is activated, the following additional changes
are available in the menu secondary parameters.
Parameters Value range
"DuoPulse modulation" Correction value (+/- 99)
"DuoPulse frequency" Correction value (+/- 99)
