Proper Way To Solder Wiring

Hold the two tinned wires on top of each other and touch the soldering iron to both wires.

Proper way to solder wiring. Remove the soldering iron and wait a few seconds to let the soldered connection cool and harden. Ad Download Electrical Wiring Market Reports from 10000 trusted sources. The solder wire is then applied to the front side of the terminal but is not brought into contact with the iron See figure 1.

I will show you how to solder wires together the right way to seal the solder joint with heat shrink is a must and you also need to make sure you do not have a cold solder joint. 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. Solder just turns your ductile stranded core wire into what is effectively solid core wire for the affected region which is.

After making the repair let it cool slightly. The heat shrink should be cut so that it is about a 12 longer than the area to be soldered. Place the heat shrink over the wire and keep it away from the area to be soldered.

Due to the high level of vibration found in automotive applications a proper solder joint it less ideal than a proper crimp joint For the same reason soldering isnt ideal in an automotive application wire nuts or just twisting the wires together is equally bad. Always add your heat to the bottom of the wire and add your solder at the top of the wire so the solder melts into the wire. Keep the iron in place and touch the solder to the wire until its fully coated.

At some point over the next 2-10 seconds depending on how hot your iron is the wires will be hot enough to melt the solder. Tin the soldering gun ie melt a little solder on it. Use solder with a flux core.

Crimping it the proper way. Whether its a resistor leg sticking through an eyelet or a hole in a printed circuit board or capacitor leadout wires wrapped around a turret or tag the iron should be used to heat the area where the joint is being made. Repeat this process on the other wire.
