The soldering bit (as shown in fig. 1) of the conventional general soldering device is heated by the single point of soldering tin at the end portion a of the soldering bit when in use, so that the soldering tin cannot be melted for a whole circle within 5 seconds, the wettability and fluidity of the soldering tin are poor, the sealing performance is poor, and the sealing welding of insulators of certain products cannot be realized.
