Here are some precautions to take when using a soldering iron.
1. Remove the soldering iron plug promptly after use
After using an electric soldering iron, many people keep it in a heated state with electricity, which can cause the tip of the iron to be heated to a high temperature and easily oxidize. Once the soldering iron tip is oxidized, it will be more difficult to use next time. Therefore, it is necessary to unplug the soldering iron plug in a timely manner during use.
2. Tin plating on soldering iron tip
I don't know if everyone has the habit of tin plating, but I always maintain a tin plating habit. Because after using the soldering iron, if the soldering iron tip is not tinned, the soldering iron tip will be oxidized due to high temperature, and some will directly turn black, affecting the next normal use of the soldering iron.
3. Do not use acidic soldering flux
In order to make welding more convenient, some users may use some soldering flux. Most of these fluxes are acidic and corrode the soldering iron tip severely at high temperatures.
The best soldering flux is rosin, and we should make full use of rosin as a soldering flux. Rosin can be ground into powder and mixed with alcohol, which can be used as soldering flux and have a very good effect. (25% rosin dissolved in 75% alcohol)
4. Solder selection
You get what you pay for, it's not wrong at all. Buying a good soldering wire not only allows for quick soldering, but also benefits the soldering iron tip. And some poor soldering wires are prone to uneven solder joints, burrs, and weak solder joints.
Regardless of the type of soldering iron used, it is necessary to perform daily maintenance work, such as cutting off the power supply in a timely manner, tin plating the soldering iron tip, and not using acidic soldering flux. At the end, let me add some improvements to the ordinary external heating soldering iron. If you are interested, you can try making it.
