Claims

[Claims for Utility Model Registration] 1. In a spot welding machine having a pair of electrodes arranged opposite to each other and configured to be able to conduct electric current in order to spot weld workpieces, a movable electrode 1
6 is configured to be freely rotatable and freely up and down,
Moreover, the spot welding machine is characterized in that it is provided with a holding means for holding the movable electrode 16 in a predetermined position. 2 The holding means for the one electrode 16 is the solenoid valve 1
2. The spot welding machine according to claim 1, wherein the spot welding machine is a hydraulic cylinder 9 that is operated by opening and closing operations. 3. In a spot welding machine in which a pair of electrodes configured to allow current to flow are arranged opposite each other, the movable electrode 16 is configured to be freely rotatable, and the movable electrode 16 is configured to be freely rotatable. A spot welding machine characterized by comprising a pressurizing means capable of pressurizing a workpiece interposed between both electrodes. 4. In a spot welding machine comprising a pair of electrodes arranged to face each other and configured to be able to conduct current, a holding means is provided for lowering the movable electrode 16 to a predetermined position and holding this position. A spot welding machine characterized in that the spot welding machine is further equipped with a pressurizing means capable of pressurizing a workpiece interposed between both electrodes.
