O.K. These are for a bench-mounted tool which takes the
terminals from a reel, cuts them off and crimps them properly to the
wire size. These, since they are designed to cover a large number of
different terminals and wire sizes (in part by changing dies, and in
part by adjusting strokes) have to be adjusted properly for the terminal
and wire size. But -- once adjusted, they will go through many reels of
terminals, at perhaps 10,000 terminals per reel. A production line
which has to handle multiple terminals and wire sizes will have multiple
machines, each set up to do one size properly. This is a far cry from
the ratcheting crimp tools, where each tool is set up by the
manufacturer's design for a single terminal type and wire size. (The
typical AMP PIDG crimpers do have a pair of pins which can go in one of
three pairs of holes to adjust the size of the insulation crimp for
different insulation thicknesses.)

Maintenance crimpers may come with dies for multiple sizes in a
single tool, but not production crimpers. The maintenance crimper is a
good thing to have along in case something goes wrong, but not really
right for thousands of crimps per day.

Enjoy,
DoN.
