An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

Element supply apparatus for a setting welding device, an element nest and a retrofit kit for the setting welding device as well as corresponding supply methods of a welding auxiliary joining part

A non-path-variable element switch, in particular for connecting elements, which can be passed continuously by the elements being positive-lockingly guided, in particular head-guided, therein only in a feeding direction, from a plurality of profiled tracks into a number of profiled tracks, which is reduced compared to the plurality of profiled tracks. With the non-path-variable element switch, a plurality of feeding sources with different elements are connected to a processing tool. Thereby, the element switch is characterized in that it comprises no mechanically switchable elements.
