Arc length stabilizer = 0 / 0.5 / 2.0
Activating the arc length stabilizer reduces the arc length until short circuits
start to occur. In this way, the advantages of a short, stable and controlled arc
can be used more effectively.
Increasing the arc length stabilizer causes a further shortening of the arc length
(L1 ==> L2 ==> L3). The advantages of a short, stable and controlled arc can be
used more effectively.

A change of weld seam profile or weld-
ing position can negatively affect the
welding result

Since the number and duration of the
short circuits is controlled, the proper-
ties of the arc stay the same if the
weld seam profile or welding position is
changed.
