All welding parameter set values remain stored until the next time they are
changed. This applies even if the power source is switched off and on again in the
meantime.

Start welding
To display the actual welding current during welding:
- Press the "Parameter selection" button to select the welding current para-
meter
- 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.
1
Press the "Parameter selection" button to select the arc-force dynamic parameter
2
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 properties, even when using electrodes with poor ignition proper-
ties
- 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 paramet-
ers", "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
