<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.
