The method of emergency soldering without electric soldering iron
How to solder the wire ends without a soldering iron is the easiest way to burn them with a lighter. I still remember that I liked to play with electronics when I was a child. At that time, there was no electric soldering iron, and the soldering wires were burned with a lighter at home.
Use a wire stripper to strip the two wires to expose a part of the copper wire, then twist the two wires together, use a thinner solder wire to wrap around the twisted wires, take out the lighter, and burn the solder That's it! Pay attention to use electrical insulating tape to prevent electric shock.
You don’t need a lighter. If you have an alcohol lamp, you can burn it directly with an alcohol lamp. The melting point of solder is about two hundred degrees, and the heat of the alcohol lamp can reach six or seven degrees, which is no problem at all.
Then there is another method, use iron rods or thin steel bars or copper (most soldering iron tips are made of copper, and some use alloys) to heat them to red, and then weld them. When I was young, there was a coal stove that burned briquettes in my home. At that time, I used coal tongs to burn red in the coal stove. This can also be used for welding wires. I often did this when I was a child.
If your conditions are good, you can buy tin paste, which is also relatively easy to use, but it is generally used for tin planting mobile phone chips. You only need to apply the tin paste to the twisted part of the wire and burn it with a lighter, or A high-power hair dryer can also blow it. Be careful not to forget to use electrical insulating tape for processing.
It is recommended to use an electric soldering iron. Nowadays, electric soldering irons are not expensive and very cheap. There are also 5V electric soldering irons. Although the power is small, the application occasions are unlimited!
