Storage battery terminal welding gun

The invention provides a storage battery terminal welding gun which comprises a handle and a bracket, wherein the handle and the bracket are connected to form an integrated structure, the bracket is internally provided with a welding gun body; the welding gun body is internally provided with a solder tip and a heating element for heating the solder tip; the heating element is connected with a controller which is used for controlling the heating of the heating element; the lower end of the solder tip is protruded out of the welding gun body; the bracket is provided with a welding wire; one end of the welding wire passes through a wire guide pipe and is adjacent to a fuse wire hole; the fuse wire hole is formed in the solder tip; the wire guide pipe is provided with a quantitative wire feeding mechanism which is used for quantitatively feeding welding wires; the quantitative wire feeding mechanism is connected with a trigger which is used for controlling the wire feeding operation of the quantitative wire feeding mechanism; the trigger is articulated with the handle; the quantitative wire feeding mechanism is connected with a controller which is used for controlling the wire feeding amount of the quantitative wire feeding mechanism. According to the storage battery terminal welding gun, one quantitative wire feeding mechanism is arranged, so that quantitative tin adding for the welding wires is realized, one-time automatic tin adding is realized, repeated tin adding is avoided, one-time success of welding is ensured, the tin adding amount is consistent, and electrode pole breakage caused by welding is reduced.
