Beschreibung
Zusammenfassung:	A welding device for welding a stud to a substrate along a welding axis in a welding direction, comprising an inert gas cover with a welding chamber and a holding device holding the stud within the welding chamber during welding, wherein the cover has an input channel, a distribution chamber, a multiplicity of first connecting channels and an inert gas inlet into the welding chamber, wherein an inert gas feed line can be connected to the input channel, the input channel opening into the distribution chamber, the first connecting channels opening into the distribution chamber at different distances from the input channel, the first connecting channels connecting the distribution chamber pneumatically to the inert gas outlet, and wherein a common cross-sectional area of the first connecting channels is all the greater, the greater the distance from the input channel at which the first connecting channels open into the distribution chamber.
