Indicates that
• the electrode tip must be dressed as soon as possible, or
• dressing at start is necessary.
For information on dressing, also refer to page 285.
"Tip dress request gun 1" is allocated to electrode 1, "Tip dress request
gun 2" to electrode 2.
The signal is set when the parametrizable count value (BOS) is rea­
ched, if a new tip dressing is still permitted at that time.
The relevant electrode must - depending on the programming of para­
meter "Stop at end of Stepper" - be dressed when the maximum is rea­
ched, at the latest.
To do this, the electrode‐specific dressing program (refer to "Program
selection" section "Dressing programs, page 378) must be selected and
started on the timer.
At the end of the dressing program, the timer automatically resets "Tip
dress request gun x".
If no tip dressing has been performed when maximum wear is reached,
the timer will - depending on the programming of parameter "Stop at
end of Stepper" - block and display "Dressing necessary".
Facilitates or permits positioning of the welding gun at the workpiece.
The output serves to control an additional welding gun cylinder which is
used to open the gun wider than usually.
The status of the output signal is dependent on the input signal
"Prelift 1" (refer to page 380).
