Soldering Station Weller 40 Watts Circuits Diagram


This is a Soldering Station Weller 40 Watts Circuits Diagram, WLC100 model, she is one of the simplest, however very efficient, ideal for those who want to build a small soldering station. The Weller WLC100 as the main component is a triac which controls the voltage that goes to the resistor, thus making the iron to vary the temperature. He is a very robust Soldering station has a power ranging from 5-40 watts uses the tips (SPG40) and resistance (HE40), ideal for hobbyists, students, and hobbyists

List of components 

R1 = 15 Ohms, 1/8 Watt 5%
 P1 = 250K pot
C1 = 823K, 250V
D1, D2 = 1N4004 D3 = Diac, bilateral trigger type Triac
Q1 = 400V/25A, Q4012LPH * (Teccor) or BTA08600c (Philips), or equivalent

ATTENTION: The Triac has an isolated tab, so if you need to replace sure to use the same type.
