Instant Soldering Iron

As a teenager, I had a soldering iron with instantaneous heating of Soviet production. In appearance, he looked like a gun. The soldering tip was made of thick copper wire. Its design was simple: a transformer with two windings — 220 V mains and a winding of 2 turns of a very thick wire. Already a sting from a wire was connected to a low-voltage winding, which was heated by a strong current. This soldering iron had a number of very advantageous advantages:
  • - Instant heating. 1 second and ready to go.
  • - Saving energy, since it is off most of the time.
  • - The sting can be bent to any shape. Say, to make it rectangular and in a few seconds to evaporate chips without overheating.
Of course there are drawbacks: the soldering iron is too heavy for long soldering. A poorly assembled transformer is buzzing, which is sometimes annoying. The advantages of the soldering iron are certainly more important. I decided to buy again such a soldering iron, but in the production of such no more.Therefore, I will make it myself. The main thing is to find a 220 V transformer with any secondary winding. I tore out such an old music center. Recommended power from 30 W, this hike is 40 W.

Making a soldering iron with instant heating

We disassemble the transformer and remove the iron casing.

Then we disassemble the core. Sh-shaped plates are staggered, and, in principle, easily knocked out.
