The present invention relates to a spot welding device capable of spot welding a welding subject at a desirable spot by arranging a plurality of welding guns having different angles at constant intervals. The spot welding device comprises: a welding table; a torque generating unit formed on a top of the welding table, generating torque; a jig driving device composed of a first jig driving device and a second jig driving device to transmit the torque generating unit; a welding subject jig device wherein the welding subject is joined to enable a rotation of the welding subject between first and second jigs connected to the first and second jig driving devices; a spot welding device installed in a guide rail, and formed on a position separated from the welding subject jig device at a predetermined interval; a controller controlling a supply of positive (+) power to the second jig by responding to a worker′s manipulation and controlling the welding subject jig device and the welding spot device while driving the torque generating unit to enable the rotation of the first and second jigs when welding; and a signal connecting device to transmit control signals of the controller to the welding subject jig device. |
