とを特徴とするスポット溶接装置。A device that bends one of a pair of workpieces, clamps the other, and spot-welds the clamped part, and includes a welding gun body, a fixed electrode fixed to the gun body, and a device that advances in opposition to the fixed electrode. A movable electrode arranged to be retractable, a pressurizing cylinder to which the movable electrode is connected to the tip of a piston rod, a pressurizing cylinder supported near the movable electrode so as to be movable in the same direction as the movable electrode, and a workpiece at the tip. A pre-bending member having a forming surface that is bent at a predetermined angle, and a pre-bending member disposed between the pre-bending member and the piston rond to move the pre-bending member forward together with the movable electrode when the piston opening and the rad move forward; A spot welding device comprising: an elastic member that is compressed after preliminary bending by the bending member to further advance only the movable electrode.
