The soldering iron is any homebrew. But those who have to deal with modern electro – and radio equipment, this tool is something special. And the requirements for it are quite hard: with small size, low supply voltage and low power consumption to ensure the excellent quality of soldering. And with the maximum comfort, including temperature controller soldering tip and a stand with a tray under flux solder and tinning.
I was very satisfied with the domestic electric soldering iron of APSN-40/40 with a homemade multi function stand. Made sure: everything works is not worse than advertised foreign counterparts, although the cost is minimal. And materials for soldering such a complex the most that neither is available.
Textolite on the basis of a fixed rack, bath, elements of the temperature controller. In order to use heavier construction transformer 220/40 V (weight not less than 1.5 kg, the power given the efficiency -50 VA) applied condenser lowering the supply voltage. Moreover, the values of C1 and C2 chosen so that the “extra” 175 “eaten” capacitive resistances, and the load was applied up to 45 V. To provide adjustment of the power supply are in parallel with the shunt soldering iron chain R3VD1R4.
