A device is provided for feeding an endless welding wire stored in a first container in a first coil generally concentric with a first vertical axis and a second container in a second coil generally concentric with a second vertical axis spaced longitudinally from the first axis in a given direction. The novel device comprises a track element extending in a path generally including the coil axes and extending above the coils in the given direction. A grommet, with a vertical wire receiving guide opening, is mounted on a support mechanism carried by the track element for movement of the grommet above the coils and along the path of the track element.
