Remove the damaged area:
Take a knife or scissors and cut out the affected area of the silver plated copper wire. In addition to that, also cut out the old jack installed with the cable.
Set up the Wire:
Once again, use the knife and strip off the end of the new wire. Make sure the stripped end is long enough to be connected well. Now use the lighter to heat the ends of the wire, in order to burn away any insulation if left on the tip of the wire. It will allow the connection to become strong.
Preparing the Jack:
Now take out the new jack that will be used to set up the connection. Unscrew it and you will find the points where you will have to connect the wire. Now place the jack in the vice, which is a mechanical screw apparatus used to hold the work piece. If you do not have vice, you can also place the jack on any other safe spot available to you.
Solder the Wires:
Before you begin soldering, make sure that you are going to join the right type of wires and connections. Label them first and plug in the soldering iron and allow it to heat up. Now take a small amount of solder using the soldering iron and use it to join the wires with the connectors. In a few seconds, the solder will get hardened and the silver plated copper wire will again be ready for use.
