What types of soldering irons are commonly used
1. External heat type soldering iron
External heat type soldering iron by the iron head, iron core, shell, wooden handle, power leads, plugs and other components, because of its iron head installed in the iron core inside and named.
Soldering iron head is generally made of copper material, its work is to store and conduct heat, in the use of the soldering iron head temperature must be higher than the melting point of the soldered material.
The temperature of the soldering iron depends on the volume, shape and length of the tip. In addition, in order to adapt to different welding requirements, there will be different specifications of the soldering iron head, the common cone, chisel, round beveled and so on.
2. Internal heat type soldering iron
Endothermic soldering iron by the handle, connecting rod, spring clamp, iron core, iron head composition, because the iron core installed in the iron head inside and named.
Endothermic soldering iron heating fast, high heat utilization rate (generally up to 350-C) and power consumption, small size, get more common application.
3 . Constant temperature soldering iron
Constant temperature soldering iron iron head, generally equipped with a solenoid type temperature controller, through the control of the power time and realize the temperature control. When the circuit is energized when the temperature of the soldering iron rises, when it reaches a predetermined temperature when the strong magnet sensor reaches the Curie point of magnetic disappearance, so that the magnetic core is disconnected when it stops energizing. When the temperature is lower than the Curie point of the strong magnet sensor, the magnet restores the magnetism and attracts the permanent magnet, turn on the control switch, and continue to supply power to the temperature of the soldering iron rises. So on and so forth, get the temperature is basically constant constant temperature soldering iron.
4. Soldering iron
Suction soldering iron is a kind of piston type tin sucker and soldering iron into one of the desoldering tools, has the advantages of easy to use, flexible, wide range of application, etc., the disadvantage is that each time only one soldering point for desoldering.
