The present invention relates to a method for monitoring at least one electronic switching contact for a door system for a vehicle, wherein the switching contact has a first connection for a first electrical line and a second connection for a second electrical line. The method comprises a step of reading a first signal from a first monitoring point connected to the first connection in order to obtain a first monitoring signal, a step of reading a second signal from a second monitoring point connected to the second connection in order to obtain a second monitoring signal, and a step of combining the first monitoring signal and the second monitoring signal in order to determine at least one state of the at least one switching contact.

Method and apparatus for monitoring at least one electronic switching contact for a vehicle

The invention describes a welding apparatus (), which has a current source () for supplying electrical power to at least one electrode at a welding torch () and a control system () co-operating with the current source (), linked to an input device () for entering settings for different welding parameters, several sensing means being provided for detecting various actual values of a welding process. At least one measuring device or system for sensing mechanical motion, in particular a welding wire displacement and/or a welding torch displacement or similar, is provided, which detects a surface structure of an object.
