Translations:Connecting and joining wires/31/en

A simple solution if you don't have a soldering iron handy is to use heat shrink solder sleeves. These contain a ring of low temperature solder in the centre of a heat shrink tube. Make sure the stripped ends of the wires are clean so as to accept the solder. Pass one wire in each end so that they cross over in the solder ring, then simply apply a heat gun. This simultaneously melts the solder and shrinks the sleeve to insulate the join.
