Do you know what is a constant temperature soldering iron?
The electric soldering iron is equipped with a temperature controller with a magnet in the head of the constant temperature electric iron to control the temperature control by controlling the power-on time, that is, when the electric soldering iron is energized, the temperature of the soldering iron rises. When the Curie point is reached, the magnetism disappears, so that the magnetic core contact is disconnected, and then the power supply to the electric soldering iron is stopped; when the temperature is lower than the Curie point of the strong magnet sensor, the strong magnet returns to magnetism and attracts the moving magnet. The permanent magnet in the core switch makes the contacts of the control switch close and continues to supply power to the soldering iron. This cycle goes on and on, and the purpose of temperature control is achieved.
