What is the correct procedure for melting solder to splice wires?

The correct procedure for melting solder to splice wires involves heating the wires with the soldering iron and then pressing the solder to the heated wires. This method ensures that the solder flows into the connection effectively, creating a strong bond between the wires. When the soldering iron heats the wires, it brings them to the appropriate temperature, which allows the solder to melt and adhere properly to both surfaces.

Heating just the wires allows you to control the melting of the solder more precisely, which is essential for achieving a reliable and effective joint. If you were to apply heat only to the solder or heat both wires and solder simultaneously without focusing on the proper sequence, you risk not achieving the right temperature for a good connection, potentially resulting in a weak splice or even damaged components.

This technique helps to ensure that the solder bonds not only to the wires but also fills any gaps, creating a robust electrical connection necessary for the proper functioning of the circuit being worked on.
