How to reconnect the broken wire of the 冷冻肉切片机

. If the slicer breaks, first cut the loose wire at the slicer, then install two 10cm steel heads from the guide wheel. Then use coarse sandpaper to change the diameter of the two ends of the wire to 1/2-2/3 of the original wire. The length of the wire is more than 5 cm, and the grit on the surface of the wire in the fine sandpaper is smooth. Both wire tips are cleaned with alcohol. Then use a soldering iron, solder wire and solder paste to solder the two sands of the 5cm wire tip together.
