Abstract: The present invention concerns a method and a device for automatic exchange of electrode tips for electrodes used during machine point welding, in particular, robot welding. The method during automated exchange of electrode tips during point welding, for example, when robot welding sheet metals, comprising of steps in which an electrode unit comprising holder, shaft and tip is brought into position for removal of the tip and in which the tip is gripped by one gripper (4b), whereby the shaft is gripped by another gripper (4a) and that the grippers are caused to move apart in a straight linear motion demonstrating considerable acceleration, whereby the tip is pulled loose from the shaft.
