Functions for optimising the welding process
Arc-force dynam-
ic
HotStart (Hti)
function
This function is activated at the factory.
Advantages
- 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
Legend
Hti: Hot-current time,
0 - 2 s, factory setting 0.5 s
HCU: HotStart current,
100 - 200%, factory setting 150%
I
H
: Main current = set welding current
Function
During the specified hot-current time (Hti),
the welding current is increased to a certain
value. This value (HCU) is higher than the
selected welding current (I
H
).
Anti-stick (Ast)
function
This function is activated at the factory.
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:
Set the Ast (anti-stick) setup parameter to OFF
The arc-force dynamic is used to influence the short-circuiting dynamic at the moment of
droplet transfer.
- = hard, stable arc
0 = neutral arc
+ = soft, low-spatter arc
