5.21.7 Sensor
Voltage
The sensor voltage is transmitted via PIN F of the mechanised welding torch connection socket (X53).
Outside the welding process, there is a voltage of approx. 12 V on the welding torch electrode. If the
electrode comes into contact with the workpiece or the molten pool, the short-circuit produced means that
when using the relevant interface (BUSINT X11/RINT X12), the resultant signal can be used for various
functions (e.g. workpiece search).
The output signal can be used to connect the cold wire component in order to enable fusing detection at
the end of the process.
