When loading the pen tip, the screw that tightens the pen tip should be pressed against the heating wire of the pen tip and tightened to avoid poor contact between the pen tip and the terminal, so that the tip is not hot and the terminal is overheated to burn the accessories. 2. If the terminal is too hot, it means that the tip of the pen is not tightly fixed, so use a screwdriver to tighten it in time. 3. When choosing the pen tip, you should choose the special pen tip for this machine. Don't choose iron wire and other non?heating wire materials as the pen tip, otherwise it is easy to burn all the accessories in the movement, and it is easy to get electric shock and fire. 4.Manual measurement with minor errors.
