The parameters to be programmed for using the tip-dressing function are the following ones:
PARAMETER PARAMETER DESCRIPTION VALUE
TOOLS N° Selection of the tool in which to parameterize the dressing
function
1 – 4
DRESSING Activation of the dressing function ON – OFF
DRESSING NUMBER Number of tip-dressing to be carried out 00 - 20
SPOT DRESSING Number of welding spots per tip-dressing 001 - 999
DRESSING STEPS Stepper percentage per tip-dressing 01 - 50%
DRESSING ALARM Notice welding spots number 00 – 40
ELECTROD. ALARM Pre-alarm electrodes 01 – 40
DRESSING OFFSET Tip-dressing current compensation 00 – 30%
Each time a value relevant to the tip-dressing is modified, the spots counter is cleared
and the tip-dressing is recalculated from the beginning.
TOOLS N°
This parameter permits selecting on which tool number the electrodes dressing function is to
be parameterized.
DRESSING
This parameter allows the operator to activate or deactivate the dressing function on the tool
specified in the TOOLS N° parameter. Should the stepper function be active in the selected
TOOL, a warning is displayed requesting the operator to deactivate the stepper function.
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 number of warning spots during which the DRESSING ALARM
output is enabled, requesting maintenance for the welding electrodes.
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:
