Claim 16:
17. An element supply apparatus of a setting welding device for a welding auxiliary joining part with a head and a shaft, comprising the following features:
a. a linear drive,
which is fastenable at the welding setting device and
which is configured to move an element nest provided at a movable end of the linear drive, wherein in the element nest a welding auxiliary joining part is releasably receivable, and

b. the element nest is movable by means of a linear movement of the linear drive in a first movement direction at least to a joining location of the welding auxiliary joining part, wherein
c. the element nest includes two element jaws that are arranged opposite each other and spring relative to each other, with which the welding auxiliary joining part is releasably holdable and which are floatingly supported in a plane perpendicular to the joining direction,
d. as a mechanical stop alignment, the element nest comprises a contour piece with an abutment contour face adapted to an outer shape of an electrode punch and
e. the element jaws are laterally fastened at the contour piece in a springy manner and the contour piece is arranged in a springingly deflectable manner in at least two directions within a plane perpendicular to the joining direction, wherein
f1. the element nest is supported in a plane approximately perpendicular to a joining direction in a floating manner, in order to be positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch,
and/or wherein

f2. the element nest is connected with the movable end of the linear drive via a mechanical direction-changing coupling component so that the element nest is movable in a second movement direction by means of the linear movement of the linear drive in the first movement direction so that the welding auxiliary joining part is positionable at the joining location, wherein the second movement direction is oriented at an angle unequal 0° and unequal 180° with respect to the first movement direction.
