Checking your soldering iron You should carry out the basic checks every day. With the iron unplugged and cold, inspect for: 32 ᭹ Damaged cables – on the iron or the power unit. ᭹ There should be no splits, cuts or burn marks. ᭹ No loose or broken cable clamps, on the iron or the power unit. ᭹ Check the condition of the tip. ᭹ There should be no pits or holes in the plating. If it is damaged then it will need to be replaced. ᭹ To ensure that the temperature of the tip remains under tight control it is necessary to rotate the tip in its holder – preferably twice a day.

Twist the strands using the stub. On some tools the cutting blades are flexible and form themselves around the conductor as they cut through the insulation, which is then pulled away by the action of the jaws. 23 3. 4. Cable strippers The outer sheath of multicore cables has to be removed without damage to the inner cores. There are several types of stripping tool available and although the actual detail differs between types, a representative tool is shown here. ᭹ The cable clamp is spring loaded.

The shape of the jaws determines the shape of the crimp. The jaws therefore are special to a particular type of crimp connector and will only give a correctly terminated joint with the appropriate parts. ᭹ In this typical example the jaws are held in by the two screws A and B. Operation The actual detail of using crimp tools varies with the type of crimper you are using. However, there are some general points worthy of note. 36 ᭹ The wire barrel of the crimp connector is placed centrally in the jaws and the handles are squeezed together.
