    Abstract: A chuck assembly for automatically ram feeding large diameter flange studs. A chuck body has a first resilient chuck disposed at one end thereof and a reciprocating second resilient chuck movable through the body from a first loading position past a passageway to which the studs are loaded to the loading chamber to a second welding position concentric within the first chuck. The dimension of the first chuck is such as to retain the flange of the stud and the dimension of the second chuck is such as to pick-up the shank of the stud and support it as the stud is ram fed through the first chuck into welding position during which the fingers of the first chuck grip the fingers of the second chuck to aid in supporting the stud.
