What kind of solder do you use to solder a wire?
Try sourcing some ‘alli’ solder, it may work for your particular wire. If you want the kids to be able to solder the wire, it will be good for you to tin it first, as the flux fumes are also nastier than those of conventionally fluxed solder.
Why do I need a well soldererd connection for switched power?
Wrap the wire tightly enough around the stripped portion of the switched power lead that it can’t be moved when tugged on slightly. This prevents the wires from moving around and helps conduct the heat from the soldering iron to both sets of copper strands. A well soldererd connection will have the solder drawn into the twisted wires, themselves.
How is solder distributed in a switched accessory?
Holding the iron below the wires allows the heat to travel upwards while gravity pulls the molten solder down. Capillary action plays an important role in distributing the solder throughout the splice. Touch the iron and solder to a few points on the splice to make sure it is uniformly spread throughout the wire strands.
Can a child be solder to a wire?
If you want the kids to be able to solder the wire, it will be good for you to tin it first, as the flux fumes are also nastier than those of conventionally fluxed solder. You might be better off introducing them to ‘croc clips’, and just leave it with them that some wires are difficult to solder.

How does iron, wire and solder placement work?
An example of ideal iron, wire and solder placement: The heat is transferred to the wire which, in turn, heats the solder to its melting point. When melting the solder to the wires, try not to touch the iron with the solder. Instead, allow the iron to heat the wire to the point that it melts the solder.
Is it OK to solder a power cord?
The gasses released by the insulation during soldering may be harmful to the person doing the work. My opinion is that it is fine to solder directly, as long as the additional risks are compensated for in some way; derating, additional insulation, additional anchoring, and good airflow during soldering.
