HotStart function To obtain the best possible welding result, the HotStart function will sometimes need to
be adjusted.
Advantages
- Improved ignition properties, even when using electrodes with poor ignition proper-
ties
- Better fusion of the parent material during the start-up phase, meaning fewer cold-
shut defects
- Slag inclusions largely avoided
The setting of the available parameters is described in the section "Setup settings",
"Setup menu - level 2".

Function
During the specified hot-current time (Hti),
the welding current is increased to a cer-
tain value. This value (HCU) is higher than
the selected welding current (I
H
).
Anti-Stick func-
tion
As the arc becomes shorter, the welding voltage may also fall so that the rod 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 weld-
ing 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.
