Soldering Iron Temperature Controller
Being a electronics geek we have to know detail about soldering temperature. Here is the circuit of simple soldering iron temperature control, in order to control or limit soldering temperature.
Circuit Description of soldering iron temperature controller
The circuit of soldering temperature controller is designed and fabricated using DIAC and TRIAC with its corresponding passive components. The varying of temperature from zero to maximum is done by TRIAC where DIAC is used to control the TRIAC firing in both directions. The potentiometer used here is for setting the temperature of the soldering iron.
Resistors (all ¼-watt, ± 5% Carbon)
R1 = 2.2 KΩ
VR1 = 100 KΩ
C1 = 0.1 µF/400V
DIAC1 = DB3
