The characteristic parameter sets the slope for the falling welding current characteristic.
When welding cellulose electrodes, the characteristic slope is the most important criterion
for the weld properties.
If the cellulose electrode has a tendency to stick, adjust the characteristic parameter to a
higher level (flat characteristic).

The arc-force dynamic parameter can only be set when carrying out the MMA weld-
ing process.

The arc-force dynamic parameter is used to
influence the short circuit current at the mo-
ment of droplet transfer.
If the rod electrode has a tendency to stick,
adjust the arc-force dynamic parameter to a
higher level.
-
Level 0 = particularly soft, low-spatter
arc
-
Level 3 = particularly hard, stable arc
