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

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

Anti-Stick func- As the arc becomes shorter, the welding voltage may also fall so that the rod
tion electrode is 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 begins 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 few-
er cold-shut defects
Slag inclusions largely avoided

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 cur-
