Arc length stabilizer with change of weld seam profile and position
Arc length stabilizer not activated
A change of weld seam profile or welding
position can negatively affect the welding
result
Arc length stabilizer activated
Since the number and duration of the
short circuits is controlled, the properties
of the arc stay the same if the weld seam
profile or welding position is changed.

Example: Stick out change
Arc length stabiliser without penetra-
tion stabiliser
Arc length stabiliser with penetration
stabiliser
The advantages of a short arc are main-
tained even if the stick out is changed,
since the short-circuit properties stay the
same.
If the stick out is changed with the pene-
tration stabiliser activated, the penetration
also stays the same.
The short circuit behaviour is controlled
by the arc length stabiliser.
