4 Soldering
4.1 Tinning Stranded Wire
Fine-stranded wires are hard to solder because their strands go in all directions when sol-
dering. The battery clip wire ends show how perfectly tinned wires should look. Cut off
the tinned parts and strip about 5 mm of the wires. Then twist the strands evenly be-
tween your fingers. This makes the wire more stable.
Heat one wire end with the soldering iron and add a little solder. Heating melts the solder
immediately and covers the wire piece with a solder film. Don’t take too much time when
tinning, because extended heating will also cause the wire insulation to melt.
Figure 26: First twist the strands between your fingers.
Figure 27: The twisted wire must be heated and some solder added, which melts at once.
