Functions for optimising the welding process

Arc-force dynam-
The arc-force dynamic is used to influence the short-circuiting dynamic at the moment of
ic
droplet transfer.
-
0 = neutral arc
+ = soft, low-spatter arc
HotStart (Hti) This function is activated at the factory.

Anti-stick (Ast) This function is activated at the factory.
function
As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tend to stick. This may also cause the rod electrode to burn out.
Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode be-
gins to stick, the power source immediately switches the welding current off. After the rod
electrode has been detached from the workpiece, the welding process can be continued
without any problems.
Deactivating the function:
1
= hard, stable arc
Improved ignition properties, even when using electrodes with poor ignition properties
Better fusion of the base material during the start-up phase, meaning fewer cold-shut
defects
Largely prevents slag inclusions

Function
During the specified hot-current time (Hti),
the welding current is increased to a certain
value. This value (HCU) is higher than the
t (s)
selected welding current (I
