Abstract
A stud welding apparatus comprises a feeder to receive a plurality of studs and feed the stud one by one with the stud being fed in advance of a weld portion thereof from an outlet of the feeder; and a welding gun to receive the stud as fed from the feeder through a feeding pipe to hold the stud and to weld the stud to a workpiece. The outlet of the feeder is provided with a shuttle loader wherein a hollow shuttle is loaded to a rod body of the stud to extend the length of a short stud, so that the shuttle loaded stud is lengthened as a whole to prevent the shuttle loaded stud from tumbling in the feeding pipe and/or a stud path in the welding gun.
