End Cap Procedure
Note: Shield work area from environmental
factors such as wind as it will cool the joint
temperature making brazing difficult and
disconnect power from the heating cable before
attempting any repairs or modifications to the
heating cable.
Expose heated section such that approximately
12 in (30 cm) minimum of cable and end cap is
accessible.
Remove old end cap by cutting through cable with a
hacksaw as close as possible to the solder on the end
cap.
Note: Do not remove more than 3% of length
of heated section. If more than 3% must be
removed to facilitate the repair or modification,
a new MI cable tag must be ordered (see Section
2.3).
Note: Ensure that the portion of the cable
being worked on can be moved away from the
surface at least 6 in (15 cm) to allow access when
brazing.

damage the copper sheath.
