Classification of electric soldering irons and precautions for using electric soldering irons
Soldering iron is divided into internal heating type and external heating type according to the form of heating tube
Small power is generally internally heated, while larger power is mostly externally heated
Internally heated, electric soldering irons are smaller and cannot be used with high power. Most maintenance personnel use more internally heated electric soldering irons.
The characteristic of external heating is that the heat is relatively concentrated. Some people used to believe that external heating is not as safe as internal heating, but now the production process can meet safety requirements. The quality of an electric soldering iron is determined by the brand price.
Soldering irons are divided into tabletop and traditional types according to their styles
The soldering table is relatively expensive and can be adjusted for temperature. There is a console that takes up a lot of space and is inconvenient to carry, making it easy to fix and use.
The traditional style is relatively small and convenient to carry around, with adjustable temperature and some without pressure adjustment function.
Classification of soldering iron heads
A large part of the quality of a soldering iron depends on the soldering iron head, which can be pointed, horseshoe shaped, knife shaped, or straight shaped
A soldering iron head is a consumable item. After buying a good soldering iron, you only need to buy a soldering iron head in the future. If it is for household use, then a soldering iron tip can be used for ten to eight years without any problems.
By the way, soldering wire is also a key factor. Since you have already bought a good soldering iron, you must buy a good soldering wire. This is also an issue that cannot be ignored. Good soldering wire is sometimes even more important than good soldering iron. I am using Eleco, which is not the best brand, but it is still quite user-friendly. There are many brands of soldering wire, such as domestic repairmen, Eleco, Old A, etc. I won't recommend those from abroad. Expensive.
Precautions for using soldering iron
1. When using a soldering iron, it is important to have a stand, otherwise it can easily burn other things and cause danger.
2. The power of the soldering iron should be determined based on the workpiece being soldered, and it cannot be pulled by a large horse or a small horse. This requires summarizing experience in one's own use. One principle is to choose high power for large items and low power for small items.
3. The use of soldering iron mainly relies on the soldering iron tip, and the selection of the soldering iron tip is crucial.
4. When selecting a soldering iron, one must not try to buy a defective product at a low price. This is irresponsible to oneself and can easily lead to electric shock accidents.
5. When using a soldering iron, it is crucial to ground it. Firstly, it protects personal safety, and secondly, it also provides protection for the soldered parts to prevent electric leakage and damage to electronic components.
6. Use good soldering wire. Otherwise, I will mistreat the good soldering iron.
