You are now ready to braze the end cap to the cable
sheath.
Using a large sizzling flame (see Appendix E), heat
out the moisture from the cable beginning 12 in (30
cm) back from the end cap (begin 4 in (10 cm) back
for polymer jacketed cable), stopping 1/2 in (13 mm)
from the end cap. Immediately proceed to next step.
Note: Details on heating out (drying out) the
cable may be found in Appendix D.
