DRESSING NUMBER
This parameter indicates the number of tip-dressing to be carried out on the electrodes before
these ones become useless.
If this parameter is set to zero, the tip-dressing is not carried out.
SPOT DRESSING
It indicates the number of welding spots per each tip-dressing. The product of this parameter
multiplied by the tip-dressing number (see previous paragraph) indicates the maximum
welding spots number the control unit carries out.
DRESSING STEPS
This parameter indicates the current stepper percentage to be achieved at the end of each
tip-dressing.
DRESSING ALARM
This parameter indicates the warned welding spots number during which the ALARM
DRESSING outlet is enabled for requiring the welding electrodes maintenance.
If, at the end of the pre-alarm welding spots, the control unit has not received the
accomplished tip-dressing signal, it stops and displays the following message:
ERR 0116
SPOTS FINISHED
DRESS ELECTRODES
In order to restore operations, first clear the screen via the ERROR RESET input followed by
the activation of the signal that indicates that the dressing was done.
ELECTRODES ALARM
This parameter indicates the notice welding spots number during which the ELECTRODES
ALARM output is enabled for requiring 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:
ERR 0117
ELECTRODE END LIFE
REPLACE WITH NEW
In order to restore operations, first clear the screen via the ERROR RESET input followed by
the activation of the signal that indicates that the electrodes were replaced.
DRESSING OFFSET
Use this parameter to increase, in percentage, the starting value of the dressings welding
current after the first one.
