Characteristics of constant temperature electric soldering iron head

Because the temperature controller with magnet is installed in the head of the constant temperature electric iron, the temperature control is completed by controlling the energization time, that is, when the electric iron head is energized, the temperature of the iron rises, and when the predetermined temperature is reached, the magnetism disappears due to the strong magnet sensor reaching Curie point, so that the magnetic core contact is disconnected, and then the power supply to the electric iron head is stopped; When the temperature is lower than the Curie point of the strong magnet sensor, the strong magnet recovers magnetism and attracts the permanent magnet in the magnetic core switch, so that the contact of the control switch is turned on and power is continuously supplied to the soldering iron head.

By doing this, we can control the temperature. There are many varieties of thermostatic soldering iron heads, and ptc elements are generally used as soldering iron cores. This type of welding head can not only keep constant temperature, but also prevent static electricity and induced electricity, and can directly solder cmos devices. High-grade constant temperature soldering iron head, its additional control equipment is equipped with digital display equipment of welding head temperature, and the display temperature is up to 400℃. The welding head is equipped with a temperature sensor, and the welding temperature can be changed manually on the manipulator. If the constant temperature point is changed, the welding head will soon reach the new set temperature. The cordless soldering iron head is a new type of constant temperature welding tool, which is composed of cordless soldering iron head unit and infrared constant temperature soldering platform unit, and can complete the wireless transmission from 220v power to heat energy. The soldering iron unit assembly has a temperature concave-convex adjustment knob, which can be continuously adjusted from 160℃ to 400℃ and is indicated by a temperature concave-convex grid. In addition, an active constant temperature electronic circuit is designed, which can actively keep constant temperature according to the service temperature set by users, and the error scale is 3℃.
