Noninsulated Copper Terminals

2-15 As noted in table 2-1, the compressed air/nitrogen source CANNOT be greater than 200 psig. 3. Attach the air/nitrogen hose to the inlet nipple, making sure there is a firm connection. 4. Once the air/nitrogen source is properly attached, push down and turn the air regulator knob clockwise until the pressure on the air pressure gauge indicates between 5 to 7 psig. 5. Plug in the power cord to an appropriate grounded power supply. 6. Set the power switch to the ON position. The power lamp and heated-air-on lamp will both illuminate. (If the lights do not come on, check the switch on the gun handle. The switch must be positioned toward the front of the handle.) 7. There is a 1-minute warm-up time. During this warm-up period, ensure that the indicated air pressure increases to 10 to 15 psig on the air-pressure gauge. 8. You can now adjust the temperature control knob to the desired temperature setting. 9. You can turn the air/nitrogen pressure off and on to the gun without powering down the module by using the switch mounted on the gun handle. After you complete your task with the compressed air/nitrogen heating tool, use the following shutdown procedures: 1. Push down and fully turn the air regulator knob counterclockwise. Observe that the air pressure gauge indication drops to 0 psig and the heated air lamp goes out. 2. Position the switch on the heating gun toward the rear of the handle. 3. Place the power switch to the OFF position and observe that the power lamp goes out. 4. Allow the air/nitrogen to flow for a minimum of 1 minute to cool the heating gun. (This procedure is done to extend the life of the heating element.) 5. Disconnect the power connecter from the power source. 6. Turn off air/nitrogen source at place of origin and disconnect. 7. Disconnect the compressed air/nitrogen hose from the air inlet nipple and install the dust cap on the air inlet nipple. Noninsulated Copper Terminals The procedure for crimping a copper terminal (noninsulated) to a copper wire is as follows: 1. With a wire stripper, trim the insulation from the wire about one thirty-second of an inch longer than the length of the terminal barrel. When using a wire stripper, be sure to use the correct size stripping slot for the wire size used. Otherwise, all the insulation will not be removed or, if the slot is too small, the outside strands of the conductor will be nicked and consequently weakened. When a knife is used for stripping wire, care should be used to prevent nicking the strands. Slip the spaghetti or heat-shrinkable tubing over the wire and back far enough to be out of the way of the crimping operation.
