How to Use a Soldering Iron to Solder Wires
1. Clamp the skin of the wire with pliers and peel off a little. Remember not to strip too much when stripping the wire, as long as it is a little more than the cross section of the wire, then twist the stripped wire end, otherwise it will be welded out Has spikes that can puncture tape or heat shrink tubing;
2. Dip the removed thread in welding oil or rosin, don't dip too much, just a little, so that it is better to weld when welding;
3. Put some solder on each wire end, so that it is easy to stick when soldering the wires together. After tinning, apply a little solder oil, and put some solder on the soldering iron. Pay attention to how the solder wire and thread are pinched by hand. The arm holding the thread must have a support point, otherwise the hand will always shake;
4. Use these two fingers to clamp one of the threads, and then use two fingers to clamp the other thread, stagger the ends of the threads and keep them together;
5. In this step, gently lean the soldering iron over. After the solder on the line melts, they will be automatically welded together, and then remove the soldering iron;
6. The last point that must be paid attention to is that the hand holding the wire should not shake, otherwise the solder will not be cool enough, and the hand will shake and the solder will not be strong.
Precautions for electric soldering iron welding
It’s all written stuff, people need some experience, I’ll talk about my own experience, but it still depends on what you are welding. Generally speaking, when welding low-voltage circuits, it is best to unplug the plug when welding to avoid static electricity when it is charged. Burn out the motherboard, and if you want beautiful solder joints during soldering, you can use a welding torch to stick solder paste or rosin after soldering, and drag soldering, but it is more difficult for beginners, drag soldering is generally used for soldering chips Or on the IC, put more solder paste or rosin when dragging the soldering, and let the welding torch form an angle of about 45. It depends on the individual's operation method.
