Abstract: A resistance welding device, comprising a frame for supporting a tool configured like a clamp with two arms arranged facing one another and having respective welding electrodes, of which a first arm is integral to the clamp and the second arm is assembled with the capacity of being moved with respect to the clamp by means of a first actuator, such that respective movements along a straight trajectory can be imparted to the arms of the clamp for moving their electrodes closer to or away from one another. One of the arms has a hollow head housing the corresponding electrode in a guided manner the tip of which is suitable for receiving the support of a component to be welded on the workpiece, the head and the electrode being able to adopt at least one standby position (A) in which the electrode is inside the mentioned head; and a working position (B), in which the tip of the electrode is arranged in or exceeds the inlet of the head, accordingly placing the component to be welded outside the head.
