PROBLEM TO BE SOLVED: To provide a spot welding device capable of accurately making a spot welding gun to stand still at a desired position without applying large force.SOLUTION: In a manual spot welding device 1 including a trolley 6 movable on a mount rail 5 in the horizontal direction, and a spot welding gun 7 hung from the trolley 6, a weight body storage chamber 17 is fixed to the trolley 6 via a bracket 15, a weight body 18 is movably stored in the weight body storage chamber 17, and bottom faces 20b, 21b of the weight body storage chamber 17 are configured by inclined faces to suppress movement of the weight body 18 in the moving direction of the trolley 6. The inertia moment occurring between the trolley 6 side and the spot welding gun 7 side can be alleviated, and the spot welding gun 7 can be accurately made to stand still at a desired position without applying large force. |
