How to emergency solder wires without a soldering iron
How to solder wires without a soldering iron? The easiest way is to burn them with a lighter. I still remember that I loved playing with electronics when I was a child. There were no soldering irons at that time, so we had to use the lighter at home to burn the soldering wires.
Use wire strippers to peel off the two wires to expose part of the copper wire, then twist the two wires together, wrap a thinner solder wire around the twisted wire, take out the lighter, and burn the solder That's it! Be sure 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 hundred degrees, which is no problem at all.
Another method is to use iron rods or thin steel bars or copper (most soldering iron tips are made of copper, and some use alloys) to heat them red and then weld them. When I was a child, there was a coal stove that burned briquettes at home. At that time, coal tongs were used to burn red coal in the stove. This could also be used to solder wires. This was often done when I was a child.
If your conditions are good, you can buy tin slurry, which is also easier to use, but it is generally used for tin implantation of mobile phone chips. You only need to apply the tin slurry to the twisted parts of the wires and burn it with a lighter, or A high-power hair dryer can also blow it out. Be careful not to forget to use electrical insulating tape.
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 use occasions are not limited!
