    Soldered connections

    A variety of joints are used to prepare wires for soldering. These include:

    • Western Union splice
    • tap joint
    • twist joint

    Western Union splice

    This splice is used to join the ends of two wires in line (compare to the twist joint, below). Strip the wires for a length of 2.5 to 8 cm (1" to 3") as shown in Figure 4. Clean the wire, then twist the ends of the wire tightly together as shown.
