In almost every home, the tool kit includes a soldering iron - a special device for soldering parts. The principle of operation of this device is to melt the tin (solder) and then apply the solder to the edges of the alloy parts. In addition, using a soldering iron, you can cover the desired item with a thin layer of molten tin - irradiate it.

Soldering irons differ in tip heating technology into several types, these are:
Electric soldering irons also have their own varieties, differing in the type of power and type of heater: nichrome and ceramic. Pulse also refers to electric soldering irons, their tip heats up at the moment when it is needed. Each type of device has its own functional features, distinctive characteristics, advantages and disadvantages.
It is also called an electric soldering iron with a spiral heater, or ESPN. The heating element of this instrument is a spiral made of thin nichrome wire through which an electric current passes. In more modern models there is a nichrome element built into the insulators.
The heater is made in the form of a ceramic rod heated by electricity. Soldering irons of this type are more convenient, but most often there are fakes - nichrome, in which only the insulator is ceramic.However, real ceramic is produced by a limited number of manufacturers, and there are many cheap, low-quality imitations.
Modern models are electric or heated from external heat sources (from open flames). The name "hammer" comes from the design - a handle with a thick tip. The device allows you to solder large parts.
Soldering irons of this type do not have constant heating, and the tip heats up when a button is pressed. For convenience, such a device has a curved shape. Long-term soldering is not provided in this case, but it is convenient to operate with a pulse soldering iron for short-term work.
The tip is made of copper wire and is heated by electric current. Modern firms produce impulse instruments with removable tips and a ceramic heater.
The devices of the new type have additional functions such as power and temperature control, which makes it possible to solder both small and large parts.
The power of this type of device is relatively small, the soldering iron does not work from the mains, but on batteries and is used in cases of lack of electricity or the need to work in special conditions.
These are small USB powered soldering irons. Such a device can be powered by a car cigarette lighter and is designed for soldering small parts.
This is a rather original and convenient device that is easy to use. It is best to choose a soldering iron with an insulated handle, it will ensure safety when working and will last longer. Poor-quality soldering irons with built-in solder suction are characterized by quick failure.
This is a device with a low power - from 30 to 60 watts. They are electric, pulse and battery operated. We recommend purchasing a tool with a wooden handle.
Soldering iron tips have several varieties and are made of ceramics, copper, and can also have a silver, aluminum, nickel coating.
Such tips are installed in electric soldering irons.
Such a sting is also included in the design of electric soldering irons and devices with a ceramic heater.
Its body is made of ceramic, and the tip is usually copper plated with nickel.
The shape of the tip depends on the type of work being done. At the same time, some designs of soldering irons do not imply the use of replaceable tips, and in this case, replacing the tip becomes difficult and time-consuming. In addition, there are soldering irons with adjustable tip length.
The tips are in the form of a wedge (screwdriver), a rod with a beveled edge, cone-shaped, in the form of a needle. The most convenient, versatile shape is the shape of the screwdriver, as it is suitable for various jobs. This shape allows you to quickly heat the required part, and the solder on such a tip holds better than on other tip shapes.
The soldering iron handle must be made of materials with low thermal conductivity. It can be a wooden handle, ebonite, as well as a handle made of carbolite and PCB. Plastic handles are found on the cheapest models, they heat up quickly and can melt. The best choice would be a wooden handle, as it has the lowest thermal conductivity.
When choosing a soldering iron, you should be guided by the main criteria, such as its power, thermal stabilization and, of course, at the price of the device.
This indicator depends on the type of work. Power up to 25 watts is suitable for soldering small electronic parts, power of 40 watts is suitable for working with thick wires. Higher power, from 100 watts and above, is suitable for soldering large parts. The advantages of high-power soldering irons are their reliability and a wide range of functions, but their disadvantage is that such devices are not used in everyday life.
The power of a home soldering iron should be between 25 and 40 watts. A lower power rating will lead to the fact that the soldering will take a long time, and the quality of the result will be questionable. Excessive power will make it impossible to solder parts that could simply burn out.
Soldering irons with thermal stabilization significantly speed up the soldering process, improve its quality, and it becomes much more convenient to work, since they provide an opportunity not only to accurately set the temperature required for work, but also to maintain it. It is convenient for both beginners and professionals. The temperature controller can be either in a separate case or built into the design of the soldering iron.
Prices directly depend on the characteristics and functionality, the type of heater, the presence or absence of a temperature controller and the brand that produces the device. You can buy an inexpensive soldering iron that has good characteristics and is suitable for homework, you can choose a more expensive model with additional functions.
Inexpensive and budget soldering irons include devices that cost from 80 to 600 rubles. Most often, these are electric soldering irons with a copper tip, with a capacity of 40 watts. This also includes ceramic soldering irons with a nichrome heater, a nickel tip and a power of 30 to 40 watts - their cost ranges from 300 to 600 rubles.
Medium-price soldering irons - pulse, with a power of 70 watts (from 300 to 700 rubles), wireless and USB soldering irons, with a low power of up to 10 watts (from 300 to 1300 rubles).
A soldering iron with a durable tip and a ceramic film heater, with a power of 50 watts, has a cost of 2500 to 5200 rubles.
