The relationship between temperature and wattage

[untar]

The numbers "22W" and "315°C" have nothing to do with each other whatsoever. Of course if you set your mod to 315°C then sooner or later that temperature will be reached.
You can buy a 1000W water boiler or a 2500W water boiler, both will take the water to 100°C but the second one will be faster. In temp control you could set your temperature to 230°C and your power to 100W, that just means the temperature will be reached quickly and the mod will regulate the power down the instant 230°C is hit (if the mod is doing temp control properly that is).
Goes without saying that you can also set the power so low that the temperature will never be reached but that kind of defies the purpose of temp control.

Try with locking your resistance.

I think my mod doesn't regulate the wattage in the power mod. When I set the power at 35w, it will keep providing 35w, no matter how high the temperature gets. The tank and vapor becomes much hotter when I set on 35w than when I set on 600F.

Now I have a big concern. If it takes around 20w to reach 315C (600F) temperature for my coil, then what is happening when I vape at 30w? Is it the reason my coils have such a short life-time? It is indicated on my Vaporesso cCell that 20-35w is the range. So I shouldn't trust it and keep vaping below 20w?

I like the warm vapor produced at 30w. Is there anyway to get that without damaging the coils?

To be honest, something's wrong somewhere, as you should never ever need to set it at the max level of 150C/600F.

In temp control, the wattage settings (if you are playing with the setting), should not be the "key" setting... it would be set just high enough to reach the temp setting, and even then, you should be getting no more than a certain value that would charge as it start pulsing... as per my example earlier, I put 50-60W, BUT it just about never reaches that wattage.

This is something that you should see someone that's familiar with temp control and test things out for you in person.

I've yet to find a well built coil that goes anywhere close to over 470F maximum, as at that level, that would normally be a very hot vape.

You need to take that tank off, fire your mod in TC with no tank and it will give you a "no atomizer" message (or similar). Turn you mod off, and back on and fire again, to clear any memorized settings it may have.

Let your tank cool down, then put it back on it, make sure that you are on the correct setting (SS), and fire for a second and see if the mod ask if this is a new coil, say yes, and lock the resistance (ohm) right away.

Then set your Temp at around 300F as a starting point and lower or increase as needed.

The thing is, my mod doesn't have wattage setting in TC mode. It takes as much wattage as needed to reach that temperature, presumably without any limit.

How hot is your vapor at 600F? For me, the drip tip and the tank get hot, but the vapor is just mildly warm.

That is what power (wattage) mode is. It delivers the set wattage constantly. It does not auto-adjust wattage in wattage mode. Temp Control is the only auto wattage regulating mode. What I guess I don't understand is if your vape is too hot why are you setting it to max temp? Just turn it down. If 35 watts in wattage mode is too hot, turn it down. Try setting your Temp to about 220C, 430F and see how that does.

I need to make an update. I received the cCell coils I'd ordered, and I now realize that my coil has been half-way dead. With the new coil (same 0.5 ohm SS), 250C needs 30w, let alone with 315C. I'm wondering, what has been wrong with that coil that made it so hot at low wattage.

It's usually just the gumming up of the liquid on the coil, it's like a crust/paste that forms on the coil with usage from the heating of the liquid, can mess a coil up.

This happens with a liquid that has lots of sweeteners, something that's very common in store bought liquids.

A new coil can start at a lower setting, but as the coil gets used and this coating gets thicker, you have to increase your temp to get the same vaping experience (warm and vapour production), but at some point, the flavour is affected and it's just bad.

Another factor is metal fatigue, that with usage, the metal breaks down and simply doesn't work that well, and the thinner the wire, the faster this can happen.

If you needed to have it set at the maximum (600F), that coil was probably long dead. Cartridges are a gamble at times, some can last a few weeks, but some could last no more than a few days, and if you burn it, you can destroy a coil within a few seconds of putting it in (and why you should always start by priming that coil very well, and have your settings low and increase them as needed).

And manufactured coils will have some bad ones, bad batches, defective ones, etc.

The new coil also jumps from 0.49 to 0.59. Could it be leakage, which probably caused this darkening of edges in all my previous coils?

Different from @Imfallen_Angel's informative blog post.

It sounds like you may be trying to change and understand too many concepts at once. While temperature control is pretty simple, it's not easy when you have too many parts of it moving at once.

Ok, had to do some looking up, indeed the Vaporesso chip doesn't seem to give you access to the power setting in temp mode. That's not a red flag but it means you should ->forget about the wattage display in temp mode<- and only use your temp setting to dial in your vape.

If you're wondering why 250°C feels hot - that's simply because it is hot (some people may still like it there). 315°C is far too hot, I don't know of anyone vaping at those temps, especially with premade coil heads.
Try playing around 200°C-230°C, that should give you a vape from cool to slightly warm. All temperatures you mentioned in your posts are hot or too hot.

Again, use the temperature setting to get a temperature you like and don't pay too much attention to the wattage display in temp mode.

Did I miss it or did no one mention that for TC mode a coil has to be spaced, not compressed. If it's compressed the mod can't properly read temperature change, especially if there's intermittent contact between adjacent coils.

I don't think anyone did and you're right.
