Effects of excessively low voltage:
-
arc too short - unstable arc
-
The wire electrode is not sufficiently melted - heavy spatter due to wire electrode pen-
etrating the welding material
Arc (dynamic)

Special dynamic
With the special dynamic, a specific current value can be added to the present welding
current for the duration of the short circuit.
0
=
no special dynamic (soft arc, tending towards instability)
