Abstract
A double point welding machine has active electrodes (3,4) and passive counter-electrodes (8,9) for simultaneously welding rods (5,6) together. In order to ensure that the welding pressure is uniform at both welding points, the counter-electrodes (8,9) are mounted on a current bridge (7) carried by a pressure beam (15). The pressure beam forms part of a four bar pivotal linkage the other arms of which are formed by rams (26,27) and a second beam (24) which is pivoted at a pivot (25).
