  • Notes
  • In the 1930s the electrical cable manufacturer W.T. Henley's Telegraph Works Co. Ltd. started making "Henley Solon" soldering irons. Initially these were relatively bulky high-wattage tools, but as electronics progressed the company introduced smaller 25W and 15W "instrument" models. Spare parts such as replacement heating elements, bits and bit holders were available.

    The final range included 15W, 25W, 65W, 125W and 240W models.
    A large number of voltage ratings were available for different models, including:
    12v, 24v, 50v, 100-110v, 120-130v, 200-220v, 220-240v and 230-250v.
    The soldering irons were generally supplied with 6ft of Henley 3-core cable.

    During the 1950s, Henley Solon instrument model soldering irons were to be found in almost every radio and TV workshop in the UK. The soldering irons had no thermostatic control of bit temperature, and overheating of the smaller 15W and 25W models tended to accelerate corrosion of the bits, which could then stick in their holders. To prevent this, it has been said that RAF apprentices were required to remove the bits at the end of their work. If they failed to do so, and the bit stuck, they were put on a charge.

    Henley Solon soldering irons and spare parts were still sold after the company was acquired by the Cable Division of AEI, but they became obsolete after the introduction of thermostatically controlled soldering instruments by other manufacturers.
