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.

Welding device with a stroke compensating arrangement

Stud feeder with an adapter (1), in which a conveying duct (4) and a stud feed orifice (3) designed substantially perpendicularly to the conveying duct (4) are provided, with a cylindrical or slightly conical stud holder (2) arranged coaxially to the conveying duct (4) and with a loading pin (10) which is capable of moving to and fro in the conveying duct (4) and which displaces studs (9) from the stud feed orifice (3) to the stud holder (2), characterized in that the conveying duct (4) is formed by a tubular gripper (5) which is slotted at least over a proportion of its length, and the gripper segments (6) are resilient substantially perpendicularly to their length.
