5.14.8 Sensor Voltage

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).
