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
meter 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/
= Balance

Configuring the welding machine for mechanical arc fusion welding
Before the welding machine is commissioned it has to be configured for mechanical arc fusion welding
(cold or hot wire welding). The following basic settings are made in the Expert
menu > see 5.1.11 chapter:
1. Activate filler wire process (AW = on).
2. Hot wire or cold wire selection (HW = on/off)
In addition, wire diameter and wire return can be adjusted if required.
Read and observe the documentation to all system and accessory components!
5.3.2
Selecting a welding task by means of the JOB list
•
Select material, tungsten electrode and seam position on the welding machine controls.
The welding task number (JOB number) results from the chosen basic parameters. If no wire
speed is assigned to this JOB-number (), wire feeding will not take place. In order to carry out the
chosen welding task, the wire feed unit must be switched to the MANUELL operating mode .
