3. Release the button and rock the die back and
forth until the nest snaps into position.
4. Activate the power unit until the lower die
release button located in the ram is exposed.
5. Depress the release button.
6. Slide the indenter into position in the ram. See
Figure 2.
7. Release the button and rock the indenter back
and forth until the die snaps into position.
8. Return ram to the down position.
2.2. Die Removal
1. Actuate the upper release button located in the
“C”–head or closed head and slide the nest out of
the head.
2. Activate the power unit until the lower die
release button (located in the ram) is exposed.
3. Depress the die release button and slide the
indenter out of the ram.
2.3. Wire, Terminal, and Splice Selection (Figure 3)
Refer to the table in Figure 3 and select the
appropriate wire, die assembly, and terminal or splice.
Strip the wire to the length indicated in the table.
CAUTION
DO NOT nick or cut the wire strands.
!
NOTE
i
For aluminum-to-aluminum application, butt
splices will accept the same wire size at either
end. However, for aluminum-to-copper
applications, the size of the copper wire must be
decreased to a smaller size to compensate for
differences in the electrical properties of copper
and aluminum. It is also necessary to use a
smaller wire size when using copper wire in a
terminal. Refer to CMA range listed with each
wire size in Figure 3.
