What is the difference between constant temperature and non-constant temperature soldering iron
Constant temperature ones such as 936 are generally as much as you adjust the temperature, the error is not large, and most of them are anti-static.
The electric soldering iron is used to solder electrical components. For the convenience of use, "solder wire" is usually used as the flux. The solder wire generally contains rosin for soldering. Solder wire is composed of about 60% tin and 40% lead, and has a low melting point.
Those without a constant temperature need to be connected to wires, and they must be soldered as quickly as possible to avoid classic breakdown of the IC chip.
They have essential differences in structure, the heating element used. are all different.
Soldering iron:
It is an essential tool for electronic production and electrical maintenance. Its main purpose is to weld components and wires. According to the mechanical structure, it can be divided into internal heat type electric soldering iron and external heat type electric soldering iron. Electric soldering irons are divided into high-power electric soldering irons and low-power electric soldering irons according to different uses.
Renewal and maintenance of soldering iron tip
(1) When changing the tip of the soldering iron, please make sure that the heating element is cold, so as not to burn your hands.
(2) Turn the nut counterclockwise by hand to remove the sleeve. If it is too tight, use pliers to clamp it and turn it gently.
(3) Clear out the sundries in the heating body and replace it with a new soldering iron head. The heating method can be carried out according to the second sub-item (2) of the sixth item.
(4) If the soldering iron tip is stuck, do not pull it out forcefully to avoid damaging the heating element. At this time, you can spray the stuck part with rust remover and turn it gently with pliers.
(5) If the jamming is serious, please return it to the dealer.
