How To Properly Solder Electrical Wires

This is a bare non-insulated B or F type crimp terminal.

How to properly solder electrical wires. If you did the cable and the tag at the same time by the time the solder properly melted the wire insulation would have started to melt. The core can be soldered in the same way. The process of soldering is taking two or more wires and joining them together and then using heat to melt electrical solder connecting those two wires permanently.

This type of terminal barrel lends much better to crimp-then-solder than do pre-insulated terminals. When done properly you have a strong conductive connection that turns two separate wires into one. Take your solder and touch at the point where the iron and wire make contact.

You crimp it with the correct tooling then apply solder to the very end of the wire and let some flow into the B or butt cheek part of the terminal. The solder should be fed into the cool side away from the heat which allows it to be drawn in smoothly by the heat transfer through the wires. Remove the soldering iron and wait a few seconds to let the soldered connection cool and harden.

Use heat shrink to cover the connection. Apply Solder to the Wire. Now measure cut and solder a wire from the top right potentiometer to the bottom right one.

When the Solder is melted it will automatically create a strong bond between the connector and wire. This has a smaller metal area so wont need as long to melt the solder This time I usually put the wire through the hole in the tag and bend it slightly inwards. When melting the solder to the wires try not to touch the iron with the solder.

And allow the solder to melt. Or a bit of steel wool or fine-grit sandpaper will work in a pinch. Using a Wire Stripper Strip the Wires to Desired Length.
