[0028] During the specific implementation of the device, the repair consumables are pre-loaded into the hot melt tank 3, and then the control button 11 is operated to start the device. Subsequently, the hot melt tank 3 heats and melts the repair consumables to make the repair consumables liquid. The hot-melted repair consumables then enter the screw feeder 4 along the guide pipe 5, and are finally pushed to the reducer 6 through the screw feeder 4 to reduce their volume, and finally are welded and repaired at the welding nozzle 7.
