Weller WLC100 control knob Answered

what is the 1 2 3 4 5 mean? is the wattage, that cant be, its too low. how does the control knowb determine temperature?


It does determine wattage, but the scale is simply an arbitrary 1-5 scale. 5 is maximum power delivered to the iron, 1 is the lowest, and the others are in the middle. More wattage=more temperature.
