Zusammenfassung:	An aspect of the present disclosure provides a welding torch that includes a torch head and a torch body removably connected to the torch head. The torch head includes first and second torch-head flow paths for flowing cooling water, first and second inlets/outlets communicating with the first and second torch-head flow paths, respectively, and a movable part movable in an axial direction of the torch head. The torch body includes a torch-body flow path for flowing cooling water, and first and second connection ports communicating with opposite ends of the torch-body flow path, respectively. The first and second inlets/outlets communicate with the first and second connection ports, respectively, when the torch head and the torch body are connected to each other. The first and second inlets/outlets are closed with the movable part when the torch head and the torch body are separated.
