<p>To weld rectilinear or curved contours, there are provided electrodes with a working field (35) of a corresponding shape and which are positionned with respect to the working level (E) to freely and elastically pivot (α) about at least one axis (43). To perform a rectilinear work with split welding electrodes, an electrode support (25) has two split electrodes (9a, 9b) which are connected to the support (25) by slots (37, 39) and studs (29, 31). The side studs (29) are made of elastic material. Both electrodes (9a, 9b) are elastically kept in this configuration by means of springs (41). This arrangement allows both a vertical linear translation (z) and an inclination according to (α) of individual electrodes according to the inclination of the contour of the workpiece to be machined.</p> |
