Using these wire connectors is easy. First, strip the ends of the wires you want to connect. Then, insert the wires into the appropriate color - coded connector based on their gauge. Heat the connector with a heat gun until the solder melts and the tube shrinks, creating a sealed and insulated connection. When using, make sure the wires are clean and dry for a good connection. Avoid over - heating as it might damage the connector. For maintenance, just keep them in a dry place away from direct sunlight. If the connectors get wet, dry them thoroughly before use.
