Combination Of Penetration Stabiliser And Arc Length Stabiliser - Fronius TPS 320i Operating Instructions Manual

Arc length stabiliser with change of weld seam profile and position

tion 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.

Arc length stabiliser not activated
A change of weld seam profile or welding
position can negatively affect the welding
result

Arc length stabiliser 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.

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.
