I (A)
Example of HotStart function
Setting examples:
HCU = 100
The HotStart current is adequate to the actually set welding current I
The HotStart function is not activated.
HCU = 170
The HotStart current is 70 % higher then the actually set welding current I
The HotStart function is activated.

MMA welding mode
Use the adjusting dial to set the desired welding current.
The welding current value is shown in the left-hand digital display.
All the parameter set values that have been set using the adjusting dial are saved 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
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
