Pneumatic Connection (Air Feed)
1.
The air feed applicator uses a double-acting air cylinder that must be actuated by a 4-way air valve.
2.
The air cylinder is equipped with push-in fittings for 6mm diameter vinyl or Nylon tube. Adapters are included for ¼”
diameter and 4mm diameter vinyl or Nylon tube.
3.
Pneumatic tubes must be connected as shown in Figure 4.1.1.
Tubes are typically connected so the terminal feed is forward
when the applicator ram is up.
4.
When using the TM-3000 or TM-4000 presses, connect the
tubes to the press air valve as shown in Figure 4.1.2
4.2 How to Make a Crimp
Review the ATS document, and strip the wires to the recommended length.
1.
Close the guards and power up the machine. Aim the work light as necessary on the crimp tooling.
2.
Insert the wire through the guard door and against the wire stop assembly target.
3.
Apply light pressure to the wire at this time. Do not push the wire to where it is under tension and bends.
4.
Depress the foot switch to activate the press and make the crimp. Then, remove the crimped wire from the
machine.
5.
Evaluate the crimp for any necessary adjustments.
Note:
Molex recommends performing a setup with the crimp height cams at their loosest setting (A, 1) to verify that the
feed and cutoff are functioning properly. This will help prevent tooling damage.
4.3 Crimp Height Adjustments
1.
Insulation crimp height
is adjusted by rotating the insulation adjusting cam on the ram. See Figure 4.3.1. The loosest
(highest) crimp height is position
1
, and the tightest (lowest) crimp height is position
29
. Each click of this cam is
approximately 0.025mm (.001”) adjustment.
2.
Conductor crimp height
is adjusted by rotating the conductor adjusting cam on the ram. See Figure 4.3.1. The
loosest (highest) crimp height is position
A
, and the tightest (lowest) crimp height is position
N
. Each click of this cam is
approximately a 0.015mm (.0006”) adjustment.
3.
Insulation and conductor crimp height adjustments are independent. Adjusting one does not influence the other.

Note:
The TM-3000 and TM-4000 presses have air valves with ¼” diameter tube fittings. Be sure to
install the ¼” diameter adapters in the air cylinder fittings, and use ¼” diameter vinyl or Nylon tube.
