摘要：1. Welding-wire feed device, which is provided with a pair of axially parallel

rollers (3, 5), installed in one plane, for feeding the welding-wire foward, the wire beinginserted between the rollers and at right-angles to their axes, and which is provided witha welding-wire guide (15), this guide possessing a tube-like wire passage (23) and a gap(26) which, in the plane of the rollers, passes through the wire passage, it being possibleto introduce the rollers into this gap, as far as the wire passage (23), and to introduce thewire-exit end of the welding-wire guide (15) into the opening of a connecting element (17,18) of a welding-wire conductor, characterised in that the welding-wire guide (15) can bepushed into the opening of the connecting element (17, 18), is laterally guided in theopening, and is composed of two strip-shaped guide rails (19, 20), which are joined alonga butting surface, at least one of these rails possessing a channel (21, 22) in the buttingsurface, the gap (26) passing through them over a portion of their length in the region ofthe channel, and is divided, by the gap (26), with reference to the rollers (3, 5) and to thefeed direction, into an entry-guide and an exit guide, and is provided, in the region of theentry-guide and in the region of the exit guide, with, in each case, a transverse shoulder(27, 28), the transverse shoulder (27) of the entry-guide interacting with a stop (16) of asupport (2) for the rollers (3, 5) and the transverse shoulder (28) of the exit guideinteracting with a stop (18) of the connecting element (17, 18), and the distance betweenthe two transverse shoulders (27, 28) being equal to that between the two stops (16, 18).
