C. Insert the wire into the pin. Check that the insulation is in the strain relief crimp area but not in the bare
wire crimp area. Crimp the pin onto the wire. A good crimp is very important A good crimp is very important A good crimp is very important A good crimp is very important A good crimp is very important. . . . . Poor crimps Poor crimps Poor crimps Poor crimps Poor crimps

D. Pull Test: Pull (approximately 3 to 4 pounds) on the wire near the connector with one hand while
holding the connector with the other hand. If the wire pulls out of the connector, you must start over
using a new connector.
E. A well soldered connection at the crimp can be reliable. Soldering a TC wire requires a lot of heat to
produce a good solder connection. Also, when soldering a TC wire each wire should be scraped with
a knife to expose fresh metal just before crimping and applying solder. Fluxing the TC wire can also
help. Do not use acid core solder or acid flux.
