Leading-out wire welding tool

The utility model discloses a leading-out wire welding tool which comprises a cooling device and a clamping device. The cooling device is of a tubular structure, and the two ends of the cooling device are opening ends used for being connected with water pipes. In the working process, the two ends of the cooling device are connected with the water pipes, a leading-out wire is installed to the surface of the upper side of the cooling device in a pressed mode through the clamping device and then is welded, and the purpose of cooling is achieved through water flowing in the cooling device. According to the leading-out wire welding tool, the leading-out wire is clamped tight through the clamping device and then is welded, so that the leading-out wire is quickly and accurately positioned, work efficiency is improved, and the welding quality of the leading-out wire is guaranteed. In addition, the water flows through the cooling device in the welding process and after the welding process, so that the effect of timely
