Hotstart function To obtain optimum welding results, it will sometimes be necessary to adjust the hotstart
function.
Benefits
- Improved ignition, even when using electrodes with poor ignition properties
- Better fusion of the base material in the start-up phase, meaning fewer cold-shut de-
fects
- Largely prevents slag inclusions
For details on setting the available welding parameters, please refer to the "Rod elect. set-
up 2nd" section.

Start current HCU must be > 100.

ing dial 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.
