Proper Way To Solder Wiring
And with that now you know how to solder wires so go practice on some wires.
Proper way to solder wiring. Heat the wires so they are hot enough to melt the solder then apply the solder to the twisted wires not the tip of the iron. Solder needs to flow onto the parts to make a good joint and this requires proper soldering technique. Automotive wiring should be soldered and protected properly in order to withstand all types of weather rain snow and salt.
You can touch the solder to the wires not to. Twist the wires together. Solder just turns your ductile stranded core wire into what is effectively solid core wire for the affected region which is.
Hold the two tinned wires on top of each other and touch the soldering iron to both wires. Clean the ends of the stripped wire with some sandpaper or steel wool. At some point over the next 2-10 seconds depending on how hot your iron is the wires will be hot enough to melt the solder.

Always add your heat to the bottom of the wire and add your solder at the top of the wire so the solder melts into the wire. This process should melt the solder and coat both wires evenly. Once the connection evenly turns the correct silver color of solder remove the soldering iron and allow the joint to cool.
Use heat shrink to cover the connection. Melting on the side opposite the heat guarantees that the solder will really adhere to the copper rather than just coat the outside. But even in the soldering community theres still room to argue.
