Abstract
A welding device, in particular a stud welding device with a stroke compensating arrangement comprises a clamping member cooperating with a dragging sleeve and a conically shaped region of an actuating pin capable of reciprocating in its longitudinal direction. The dragging sleeve at least partially surrounds the clamping member and the region. The clamping member is designed in the form of a hollow cylinder with at least one elastic portion which can be brought to rest radially on the dragging sleeve by the region, and a carrier member is provided on which the clamping member rests in part.
