The mode can ensure that the tin wire keeps contact with the driving wheel without sliding, realize continuous tin feeding and improve the overall efficiency. The lower end of the tin guide pipeline penetrates through the heat radiation fins 3 to be communicated with a molten tin channel 15 arranged in the soldering iron head 2, a heating core 12 and a thermistor 13 are arranged in the soldering iron head 2, and a pressing type potentiometer 10 and a temperature adjusting knob 11 are arranged on the outer side of the handle 1. The electric soldering iron is also internally provided with a circuit board 9, and the circuit board 9 is connected with a push type potentiometer 10 and a temperature adjusting knob 11 to realize the control of a heating core 12 and a thermistor 13. Type-C power source 14 and control button are connected to 9 one ends of circuit board, and other end control heating element and gear motor, wherein push Type potentiometre 10 control motor advances tin speed, and tempering knob 11 controls the target temperature. When the operator uses the holding posture, the heating temperature can be conveniently adjusted, and the tin feeding speed is controlled by the thumb. The circuit board 9 is powered by a PD protocol connector, can be powered by a Type-C interface charger or a mobile power supply supporting a PD protocol, can stably output 9V/12V voltage by utilizing a corresponding PD trap module, and provides a more portable use environment under the condition of ensuring the integral heating power.
The circuit board 9 regulates the speed of the direct current motor by using a voltage regulation mode, and controls different tin feeding speeds. Different requirements are made on tin feeding amount when different elements are welded, and the simplest speed regulating mode of the direct current motor is to regulate the armature voltage of the motor.
