Use low wattage soldering gun when soldering electrical
wires, connectors, terminal lugs, and receptacles. High
wattage soldering guns may damage parts by overheating.
1. Solder connection must be bright and clean before soldering. Remove dirt and grease with a wire
brush (item 2, WP 0085) or a pocket knife. Solder used must be of lead alloy (item 13,
WP 0085) with soldering flux (item
5, WP 0085). All wires, parts, and soldering gun must
tinned for good connection and maximum transfer of heat.
2. To prevent overheating damage to electrical parts when soldering and unsoldering connections,
hold bare wire, lead, or terminal lug close to soldering point with long roundnose pliers. Pliers act
as heat sink and absorb excess heat.
HEAT SHRINKABLE TUBING
Use the heat shrinkable tubing (item 19, WP 0085) to insulate soldered and crimped electrical
connections as follows:
a. Cut desired length of new heat shrinkable tubing twice the length of the connection to be
b. Slide the heat shrinkable tubing onto the wire and out of the way before making electrical
After making electrical connection, slide heat shrinkable tubing into place over electrical
DO NOT touch heat shrinkable tubing for at least 30 seconds
after heating. Heat shrinkable tubing is hot and will burn you
causing serious injury or death.
d. Hold hot air blow gun 4-5 in. (10.2-12.7 cm) away from heat shrinkable tubing and apply heat
for approximately 30 seconds. Stop applyling heat as soon as heat shrinkable tubing forms to
the shape of the electrical connection.
