An apparatus, in particular for pointing electrodes for TIG welding, is described, wherein the electrode (8) is fed toward the side of a grinding disc (3), whereby the electrode is pointed. The apparatus comprises a first element with an upwardly facing carrier face (19) on which an electrode (8) may be placed in an insertion position, and a second element with a downwardly facing engagement face (10, 11) for securing the electrode in a lateral direction in a grinding position, said two elements being mutually movable between the insertion position and the grinding position. The feed device of the electrode comprises a drivable roller (24) preferably of an elastomeric material, adapted to press the electrode laterally toward the grinding disc (3), and the axis of rotation of the roller forms such an angle with the longitudinal axis of the electrode that the roller by rotation moves the electrode toward the grinding disc. The apparatus is advantageous by being easy to use so that the maintenance of the electrode for TIG welding is facilitated, which is essential for the achievement of a good weld. |
