[0002] During the soldering process of circuit boards or wires, the user needs to bring the welding gun into contact with the tin wire. After the welding gun melts the tin wire, the liquid tin wire will fall on the area to be soldered, and after the tin wire cools down, it will stick the connection together.

[0003] The general welding method requires the user to hold the tin wire and gradually feed it out, so that the end of the tin wire is always in contact with the part to be welded. This feeding method requires the welder to hold the tin wire to feed it, which is troublesome and not conducive to the user's welding operation. Utility Model Content
