Soldering Techniques

The most important step in this repair procedure is the proper soldering of each connection.

1. Use a soldering gun or a high output pencil type soldering iron so the joint can be heated quickly, without transferring too much heat into the wires. Use only thin, rosin core lead solder.

2. Place a block of wood underthe splice to be soldered to give a base to push against and prevent the soldering gun or solder from touching other wires.

3. Heat the connector, not the wires or solder.





4. Feed the solder into the end of the connector, as shown in the illustration. The solder will be drawn into the connector, towards the heat. If the solder beads up, the connector may not be hot enough or there may not be space in the connector to draw the solder into it.

5. Feed solder into the connector until the connector appears to be filled.

6. Continue heating the connector for a few seconds after removing the solder to allow good penetration. Check to be sure that there are no sharp points of solder that may rub and cut into other wires.
