You should be using resin core eutectic solder, made especially for
electronics. You can get it at Radio Shack. Regular flux soldered
joints will eventually corrode when used for electrical stuff.
The trick is to tin the wire ends first. Start with a clean iron.
The easiest way to clean an iron is to wipe it in lots of dry cotton
cloth. Watch so you don't burn your hand or start a fire. Don't
use synthetic cloth, it melts. An old all cotton T shirt works real
Strip the insulation away from about 1/2 inch of the end of each
wire. Twist the wire a little to make it a stable diameter, but
leave it straight.
Let the iron heat up. Hold the soldering iron under the end of wire
and when the wire starts getting hot, touch the solder to the top
of the wire. When the melting temperature is reached the solder
will melt and wick into the wire. Get the whole wire end saturated
in solder. Repeat this with the other wire.
Now, use needle nosed pliers to make a hook in each wire end and
hook them together. Crimp the hooks with the pliers so the joint
is mechanically tight. Touch the iron to the joint and touch the
solder to the other side. You will see the joint melt first, and
then the solder melt. Pull the solder and iron away and don't let
the joint move until the solder in the joint is frozen, otherwise
you will get a cold joint. If the joint does move and the solder
doesn't look right (sort of granular), heat it up again and remelt
the solder. The joint should look metallic and smooth.
Now a little electrical tape or heat shrink tubing and you're in
This is one way to do it and I know there are others. It has always
worked for me and it was the way my dad taught me when these things
