Zusammenfassung:	PURPOSE: A nut clamp for an upper electrode device of an automatic nut welding machine is provided to prevent weld defects by preventing the movement of a nut in a welding process and to stably fix the nut by supporting the outer circumferential surface of a body facing a ball with a screw thread of the nut. CONSTITUTION: A nut clamp (250) for an upper electrode device of an automatic nut welding machine comprises a nut feeder, the upper electrode device, a lower electrode, a coupling rod, a connection rod, and a clamp rod (251). The clamp rod is a cylindrical pin shape and has a recessed groove (252) at the bottom. After an elastic fixture (253) having elastic members and an elastic ball (253a) are embedded in the recessed groove, a supporting piece (252a) is protruded inward from the edge of the recessed groove to elastically support the ball.
