greets,
I've got a heating element for a soldering iron and I'm a bit confused about the leads.
The two green leads give a voltage in the range of zero to about 4 mV if I heat the element with a lighter.
The blue and red leads stay at zero when the element is heated. So I assumed that the two green leads are the thermocouple and the blue and red pair is the resistive/heating coil. But the soldering station I have (ZD-937) has the triac tied to the green wire pair, i.e. to the thermocouple (if I'm not mistaken).
Am I wrong by assuming that the green wire pair is the thermocouple, i.e. it is the heating coil because it is tied to the triac?
thanks
