Electrode
The current and polarity to be set are specified by the electrode manufacturers.
Use the positive pole welding process (connect the electrode holder at the
welding socket at the bottom) when you use basic electrodes.

Hot Start

Press the push button [11] to select the Hot Start: the control LED [12] will light
up and display your selection. If you make no change within 20 seconds, this
selection is automatically deactivated, i.e. the control LED [12] extinguishes and
the display shows the current selected. To reduce this waiting time, you may
press the push button [11] again or use the rotating button [5] to go back to the
welding current.
You may change the Hot Start value as you like for each type of electrode and
save is as a default value.  As soon as the arc has ignited, the actually
adjusted value is saved in memory.
Each electrode type has special parameters preselected to ensure an optimum
welding process. Use the following factory settings for Hot Start:

Rutil
Basic
Cellulose
To assist ignition of the electrode for electrode welding, the welding current used
at the start has slightly higher amperage than the welding current set. The value
is determined by the Hot Start preselected. Use the rotating button [5] to adjust
the selected current continuously between 0% and 200% of the current selected
(but max. Imax).
Example: Hot Start 30% and welding current=100A -> Hot Start 130A). The Hot
Start time is 0.5 seconds.
3.6.3

Arc force

Press the push button [13] to select the Arc force: the control LED [14] will light up
and display your selection. If you make no change within 20 seconds, this selection
is automatically deactivated, i.e. the control LED [14] extinguishes and the display
shows the current selected. To reduce this time, press the push button [13] again or
press the rotating button [5] to go back to the welding current.
