ABSTRACT:
A contact tip (10) for a welding head (12) includes a wear-resistant member (34) and a transverse passageway (32). Wear-inducing deposits on the surface of consumable electrodes result in shortened service life of contact tips. In the contact tip (10) of the present invention, surface contaminants are removed from electrode (28) by a hard, wear-resistant member (34) and directed radially outwardly to an external surface (16) through a transverse passageway (32). The present invention is particularly useful in high duty-cycle automatic or robot-controlled welding operations.
