Is there a short answer as to how TC differs from W in terms of voltage, current and resistance delivered and why the different metals mean each is only suitable for one setup or another?
To be honest, TC is not an area that I can comfortably give much info or any advice. I'm planning on experimenting with it very soon myself as I've just got my first dna250 mod recently. But so far I've been avoiding it so I don't know enough about it yet to be able to give advice on it. There will be other members who will be more suited to that topic at the moment. But I can tell you that some metals have to be used in TC mode (like Ni200) because they are much softer and less stable at higher temperatures. So the TC is used to cut the power before the temp goes above what is suitable for the metal to cope with and it either deforms and melts or a chemical reaction happens and potentially releases harmful particles. The wires used in power mode are stronger and can withstand much higher temperatures without negative effects on the metal.
In a couple of sentences, as I understand it, the only real difference is that in TC mode the mod will deliver the power up until the specified temperature is reached and then it will automatically cut the power to stop the coil exceeding the temp limit set by the user. So it's like having a motorbike with a rev limiter set to 6000rpm. Whereas in wattage mode there's no limiter so you can basically rev it till the engine blows up if you want to. But in TC when you hit the 6000rpm it will stop you going any higher either by cutting the power completely or, I would expect, by pulsing the power to maintain it at that temp level. Resistance would make no difference which ever mode is used. And the voltage will depend on how much power is needed to maintain the temperature that's been set.
Hope that made some kinda sense. Like I said, I'm sure someone with more TC knowledge can do a better job explaining it.
I know @simong uses TC. Maybe he can help?
