How big a soldering iron is usually used to repair electrical appliances at home?
Electric soldering iron is a must-have tool for daily maintenance, electronic DIY, and some handmade crafts. In fact, there are many models of electric soldering iron to choose from. Here are a few good recommendations and instructions for use.
Introduction to Electric Soldering Iron
Electric soldering irons are mainly composed of a soldering iron tip, a heating element, a handle, a power cord, and a transformer (the soldering station has a transformer). According to their mechanical structure, electric soldering irons can be divided into two categories: internal heating and external heating. To determine which one is better, it can only be said that each has its own advantages and disadvantages, as well as its own uses.
Why is it called internal heating type
The tip of an internal heating electric soldering iron is hollow, as anyone who has used it should know. Because the internal heating type soldering iron has a unique structure, its heating element is directly inserted into the interior of the hollow soldering iron tip, so it is named the internal heating type soldering iron. The power of an internal heating soldering iron is generally small, usually below 60W.
Why is it called external heating type
The tip of an externally heated soldering iron is solid, and its heating element directly wraps around the solid tip, hence it is called an externally heated soldering iron. External heating soldering irons generally have higher power and larger volume, with many reaching over 60W.
Classification of soldering iron tips
Soldering iron tips can be divided into: pointed tip, short tip, curved tip, blade tip, small blade tip, thin blade tip, horseshoe shaped, one character tip, long round tip, short round tip, and round tip.
Purchase recommendation
External heating soldering iron is relatively cheap, but it heats up slowly and generally cannot achieve temperature and constant temperature. Although this soldering iron is cheap, its actual use is not very good. The author once spent eight yuan to buy an external heating soldering iron as shown in the picture below, which hung up shortly after use.
External heating soldering iron
Because its soldering iron tip is very prone to oxidation, the soldering iron is basically useless when the soldering iron tip oxidizes. In addition, due to its relatively large size, some soldering is not very convenient, so we no longer recommend external heating soldering iron here, but directly recommend internal heating soldering iron.
Therefore, it is recommended to use an internal heating soldering iron. Here, we recommend a relatively good and easy-to-use internal heating soldering iron, which is the Gaojie Huanghua 907 soldering iron (search Huanghua 907). Friends who have used it should know that this soldering iron is very durable and can adjust temperature, with a very fast heating speed.
