ABSTRACT:
Proposed is a device for welding metal elements, in particular studs, to structural parts, having a welding head that has a collet chuck for the accommodation of an element, having a feed unit for the feed of elements into the chuck, and having a power supply means for the supply of electric energy for a welding procedure. The chuck has at least two segments electrically insolated from one another. It can be detected via an applied test voltage whether a metal element to be welded is located in the chuck.
