出装置。 The electrode tip of the welding gun is rotatably supported at both ends so as to cross the return path of the cooling water after cooling the electrode tip by directly contacting the electrode tip, and crosses the return path. The portion has a sharp top edge along the longitudinal direction on one side with respect to the longitudinal axis,
By having a relatively heavy thick wall portion along the longitudinal direction on the side directly opposite to the top edge with respect to the longitudinal axis, when the flow rate of cooling water is large, the top edge side is moved by the action of water pressure. a hydraulically responsive member that directs the thickened portion toward the upstream side of the cooling water by a descending action due to the weight of the thick portion overcoming the action of water pressure when the flow rate of the cooling water is low; detection means for detecting detachment of the electrode tip of the welding gun by rotating around the longitudinal axis in response to water pressure and detecting that the thick portion is directed upstream of the cooling water; A welding gun electrode tip detachment detection device, characterized in that:
