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)
Characteristic parameters for dynamic standard arcs
Characteristic slope
Resistance value [Ohm] with which a drooping or neutral characteristic can be set.
32767 = drooping characteristic
0 = neutral characteristic
(1) Static range (9) Short circuit
(2) Dynamic range (10) Welding current
(3) Current rise = 0 (11) short circuit current
(4) Current rise (12) Special dynamic
(5) Special dynamic (13) short circuit current
(6) Current rise = 65535
Special arc force dynamic = 0
(7) Current decrease = 65535 Special dynamic = 65535
(8) Current drop = 0
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)
65535 = maximum special dynamic (hard, stable arc)
