The present invention describes an element supply device of a setting welding device for a bolt-like welding auxiliary joining part with head and shaft. This element supply device comprises two scissor-like arranged clamping jaw levers which define a blind hole channel with a nest-like end position for receiving the welding auxiliary joining part. Further, the element supply device comprises a first actuator and a second actuator by means of which the nest-like end position can be positioned suitably with respect to an electrode punch.
