Soldering serves as a reliable means of joining metals. Before connecting the wires in this way, they must be properly prepared and tinned. This is required to ensure the quality of the connection. Careless tinning of the wire will not provide reliable electrical contact, and over time will inevitably lead to damage to the connection.
Necessary
- - knife;
- - tweezers;
- - pliers;
- - soldering iron (soldering station);
- - solder (tin);
- - flux (rosin or solder paste).
Instructions
Step 1
Remove the insulating layer from the ends of the wires to be connected. Use a knife to do this, using it to cut the insulation in a circle and gently pull it out. The length of the cleaned section of the wire is determined by the method of connecting the wires and can be 10-30 mm.
Step 2
Use the tip of a knife to strip the wire until it shines. This is necessary to remove residues of the insulating layer and oxides from the metal core. If the wire is made up of many thin copper strands, fluff the end of the wire into a fan before stripping. After stripping, twist the stranded wire so that it does not fray.
Step 3
Preheat the soldering iron by plugging it in. Make sure the tip of the soldering iron is clean. If necessary, clean it from oxides with a file or a needle file and rub the heated tip of the tip on a wooden plank several times. Place a soldering iron on the exposed part of the wire to warm it up as well.
Step 4
Touch the tip of the soldering iron to the rosin, then to the piece of solder so that it is evenly distributed over the working surface. Bring the tip to the wire you want to tin. If the wire is sufficiently hot, the solder will be evenly distributed over the surface of the wire harness.
Step 5
To improve the efficiency of the operation, rub lightly with the sting along the wire on different sides. To prevent burns, hold the wire with tweezers or pliers.
Step 6
If it spreads or evaporates quickly, dip the tip of the soldering iron into it again, and then draw up another portion of the solder. The molten rosin should wrap around the entire contact surface of the wire. If the wire is thoroughly stripped, the tinning process takes place rather quickly.
Step 7
Make sure the tip of the wire is covered with an even layer of solder. If the harness has poorly treated areas, repeat the tinning procedure again.
