<Tip dressed>

For welding operations during which the electrodes need to be dressed once or repeat-
edly, tip dressing must be included in the programming. When the Stepper function is ac-
tive (Programming - Welding Parameters - Stepper) the <Tipdress request> signal
indicates that the electrodes need to be dressed. This signal is reset as soon as a <Tip
dressed> signal indicates and acknowledges the completion of electrode dressing.
NOTE
If electrode number 0 is selected with the <Spot selection> signals and a <Tip dressed>
signal becomes high, the tip dress counters of all electrodes will be incremented and the
wear counters will be set to a defined value.
If electrode number 1 through n (n = maximum number of electrodes) is selected with the
<Spot selection> signals and a <Tip dressed> signal becomes high, the tip dress
counter is incremented by 1 and the wear counter is set to a defined value for the elec-
trode selected by the number of the <Spot selection> signals.
Setting the wear and tip dress counters via input signals:
