Arc length stabilizer = 0 / 0.5 / 2.0
Activating the arc length stabilizer reduces the arc length until short circuits start to occur.
The frequency of the short circuits is controlled and kept stable.
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 effec-
tively.
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.
