In order to restore control unit working efficiency, first of all clear the screen through the
DELETE ERRORS input and then activate the electrodes-dressed signal. If more than one
weld tool was activated the operator can choose which tool to use to dress the electrodes as
follows: if only the external dressing input is activated, to the control unit this means that the
electrode is being dressed on the tool used during the last weld carried out. If the dressing is
to be carried out on a tool other than the one used during the last weld carried out, the
operator uses the RIC1, RIC2 and RIC3 inputs to decide which of the four tools to use to
carry out the dressing as outlined in the following table:
RIC1 RIC2 RIC3

The required recalls configuration must be set before the activation of the dressing signal and
must be kept steady for the whole duration of the dressing signal activation.
ELECTROD ALARM
This parameter indicates the number of pre-warning spots during which the ELECTRODES
ALARM output is enabled, requesting the replacement of the welding electrodes.
If, at the end of the pre-alarm welding spots, the control unit has not received the signal that
indicates that the electrodes were replaced, it stops and displays the following message:
DRESSING [166]

In order to restore control unit working efficiency, first of all clear the screen through the
DELETE ERRORS input and then activate the electrodes-replaced signal. If more than one
weld tool was activated the operator can choose which tool to use to change the electrodes
as follows: if only the external electrodes-replacement input is activated, to the control unit this
means that the electrode is being replaced on the tool used during the last weld carried out. If
the electrode is to be replaced on a tool other than the one used during the last weld carried
out, the operator uses the RIC1, RIC2 and RIC3 inputs to decide which of the four tools to
use to replace the electrode as outlined in the following table:
RIC1 RIC2 RIC3

activation.
