The invention discloses an automatic threading?welding machine applied to fuse production, which comprises a controller and a dividing disk. The circumference of the dividing disk is sequentially provided with a feeding mechanism, a loading station, a threading station for threading two wires inside an inner shell and cutting the wires to a fixed length, a flatting station, a rosin water-staining station, a tin-staining station, a corner-folding station, a fuse-wrapping station, a double-spot welding station, a wire-pulling station, an outer shell-assembling station for coating the inner shell with an outer shell for producing a finished product, and an unloading station for finished product collection. The automatic threading?welding machine applied to fuse production has the beneficial effects that multiple types of work of the fuse can be simultaneously and synchronously carried out with one machine, functions of mechanical, electronic and detection aspects are integrated as one, quick processing and manufacturing can be realized, product performances can be detected via a detection station and an impedance test?station, inferior-quality?products are removed to ensure the finished product quality, time and labor are saved, the labor cost is greatly reduced, flexibility is high, and demands of modernized industrial?production can be well met.
