Easy way to solder wires without using a soldering iron
We sometimes engage in line maintenance outside, will encounter the need to weld wires, but due to the lack of 220V AC power and can not use a soldering iron (sometimes in the high altitude welding, soldering iron is not convenient), here are two simple ways to weld wires without the use of a soldering iron.
1, with a lighter welding wire
Welding wire with a lighter.
Using a lighter welding wire, first use wire strippers to peel the wire to reveal the copper wire, and the two wire screwed together, and then the solder wire wrapped around the line (as shown in the figure above), and then use a lighter to heat for a few moments, the solder wire can be melted will be welded to the two wires together. After welding, check to see if the welding is secure, after confirming that the welding is reliable, the wire wrapped with electrical tape can be. This welding method is very simple, even when standing on a ladder can also be welded, than with a soldering iron is convenient.
2, with a soldering iron welding wire
If the welding of more wires, you can also use the fire iron to weld. This fire iron iron head is made of red copper, handle for the steel bar folded into. When using the fire iron on the coal fire can be used to weld the wire after heating.
The use of fire soldering iron welding wire, is also the first wire thread screwed together, and wrapped in solder wire. Because of this fire iron head larger, sufficient heat, suitable for welding larger soldering points. A long time ago, some electronic hobbyists to produce discrete components of the radio, is the use of this fire soldering iron welding. In addition, this fire soldering iron can also be used to weld iron buckets or tea pots.
Fifty years ago the soldering iron is not very popular, then there is also tin soldering. Find a copper rod (must be copper), the front end with a hammer into a flat shape, in the middle of the rod drilled a small hole (diameter 8mm), with 8mm of steel on a handle, the heat source liquefied petroleum gas or coal furnace can be, copper rod flat end of the first hang good tin, not hang good tin can not be used, the copper rod heating should not be too high, 300 degrees or so, if the burning of the micro-red, copper and tin into an alloy, hang tin is not good to use, also Have to thwart this layer of alloy or grind off the re-peg tin to use. Of course, this homemade soldering iron welding component density of the circuit board is somewhat difficult.
