Process active
The signal is active for the duration of the entire process, starting with the gas pre-flows to the completion
of the gas post-flows after the process. The positioning device can be used as a condition of movement.

Main current signal
When the main welding program starts, this signal is set and reset after that program is exited. It is used
by positioning equipment as an additional trigger signal when using the current start and end programs in
the non-latched special operating mode. These are normally used for pre-heating or for treating the end
of the seam.

Workpiece touch detection
This signal is used to detect whether the welding electrode or the cold wire touches the workpiece. It is a
special function which can only be activated outside of the process (- See 5.9.1 Position search chapter).
