Hotstart Function; Anti-Stick Function - Fronius TransSteel 4000 Pulse Operating Instructions Manual

HotStart function

To obtain the best possible welding result, the HotStart function will sometimes need to be
adjusted.

Anti-Stick func-
As the arc becomes shorter, the welding voltage may also fall so that the rod electrode is
tion more likely to stick to the workpiece. 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. The welding
process can be resumed without problems once the rod electrode has been detached from
the workpiece.
The anti-stick (Ast) function can be activated and deactivated in the Setup menu for the
setup parameters for MMA welding.
Improved ignition properties, even when using electrodes with poor ignition properties
Better fusion of the parent material during the start-up phase, meaning fewer cold-shut
defects
Slag inclusions largely avoided

Function
t (s) During the specified hot-current time (Hti),
the welding current is increased to a certain
1,5
value. This value (HCU) is higher than the
selected welding current (I ).
