Abstract
A contact provided in a welding tip of an arc welding apparatus includes a tip body adapted to be mounted to a welding torch body and a tip end member formed integrally therewith. The tip end member is divided into two parts, i.e., first and second halves by means of a slit formed along the axis of the tip end member, and the first half having the predetermined rigidity is movable around a connection between itself and the tip body. A spring member fitted on the tip end member applies a spring force thereto, whereby the contact has improved durability.
