Start welding
To display the actual welding current during welding:
- Press the "Parameter selection" button to select the welding current parameter
- The actual welding current is shown on the digital display during welding.
Corrections dur-
ing welding
To obtain the best possible welding results, the arc-force dynamic parameter will some-
times need to be adjusted.
Press the "Parameter selection" button to select the arc-force dynamic parameter
Use the adjusting dial to set the desired arc-force dynamic value
The welding parameter value is shown in the digital display located above it.
HotStart function To obtain optimum welding results, it will sometimes be necessary to adjust the HotStart
function.
Advantages
- Improved ignition, 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
For details on setting the available welding parameters, please refer to "Setup parame-
ters", "Setup menu - level 2".

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 func-
tion
As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tend to "stick". This may also cause "burn-out" of the rod electrode.
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 operation can be continued
without difficulty.
The anti-stick (Ast) function can be activated and deactivated in the Setup parameters in
"Setup menu: level 2".
