Internal heating soldering iron
The soldering iron core of the internal heating electric soldering iron is installed inside the soldering iron head. The soldering iron core is made of nickel-chromium resistance wire wound on the porcelain tube. It has the advantages of fast heating, high thermal efficiency, low price, light weight, small size, fast heating and power consumption. inferior advantages.
The efficacy of the 20W internal heating soldering iron is equivalent to that of the 40W external heating soldering iron. It is suitable for welding small electronic components and printed circuits, and is widely used in instrument maintenance.
