5.21.7 Sensor current

The sensor current is transferred via the connection socket of the automated welding torch.

At the torch, the signal has to be connected to the conducting part of the cold wire feeder. This means

outside the welding process an electric potential is active which detects sticking when the feeder or wire

has contact with the workpiece at the end of the process.

If the power source is used in combination with a TIG torch please note that the torch electrode having

contact with the workpiece cannot be detected.

At present, sticking detection is only possible with a dedicated interface which analyses

the corresponding "sticking" signal at the 19-pole interface for automated welding.

The usual sticking detection of standard interfaces (RINT X12 and BUSINT X11) does

not work with this system type.
