7.4.2 Setting the welding sequence
Fig. 9 LED overview on page EN
A welding procedure consists of the following sequences:
gas pre-flow, main welding parameters and
gas post-flow
.
Depending on the end crater setting, the start welding parameter and the end crater filling
parameter can be added to a sequence.

Welding sequences
Sequence
Description
Shielding gas pre-flow (A)
This sequence allows shielding gas to flow out before the arc
ignites.
Start welding parameter (B)
The welding process is carried out with this sequence as soon as
the start signal is set.
<Parameter selection> button (C)
Switches between the welding parameters.
During welding, the set value can be displayed on the digital
display.
Main welding parameter (D)
This sequence forms the actual welding sequence.
Shielding gas post-flow (F)
This sequence allows shielding gas to flow out after the arc is
extinguished.
End crater filling parameter (F)
This sequence comprises end crater filling.
