Welding appts. for attaching fixing elements - with a rigid, axially displaceable tubular holder for fixing elements in the form of flexible sleeves

摘要

Welding appts. for attaching elongate fixing elements has a feed channel and an axially displaceable holder for fixing elements. The axially displaceable holder (5) is shaped as a rigid tube, while the fixing element (1) - which is guided and accommodated by the holder - is shaped as a flexible sleeve to ensure a large contact area with the holder. USE/ADVANTAGE - In welding equipment for attaching fixing elements to car body structures, for example. The feeding/holding unit for fixing elements is simplified. Optimal current flow is attained between the unit and fixing element during welding.
