It is known that the temperature of the soldering iron depends largely on the quality of the performed installation. Are particularly bad (if not harmful) to overheat. Immediately deteriorating the quality of the soldering, there is a risk of peeling the printed wire Board, is accelerated wear of the operating rod, and even failure of the heating element. Sting often cleaned of oxides and overheated — not holding solder.
Everyone who is somehow connected with practical electricity and radio, offered to equip an important tool for it network a soldering iron — a homemade temperature regulator soldering tip (RTG). From the well-known analogues the device is of a simple circuitry (Fig.1) in combination with a high operational reliability of the structure itself. Moreover, the parts for manufacturing the device will require very little: a triac, a pair of LEDs and three resistors (one variable).
