  • Stud-welding device
    Patent number: 4629857
    Abstract: A stud-welding apparatus in which the chuck is axially displaceable to bring the stud into engagement with a detent past which the stud has been propelled so that the stud is held as retraction of the chuck sets the stud in the mouth thereof. The chuck is then advanced to carry the stud away from the detent and into engagement with a workpiece so that the welding current does not affect the detent and mechanical stress is not applied thereto during the welding operation.
