So, for those of you running TC mods who are interested in reducing you vape temperatures, I stumbled across something interesting.
I have been playing with 30AWG Tungsten wire here recently. Long story short, I made two different coils,
one 7 wraps slightly over 3mm ID and 0.11 ohms, and
one 12 wraps 3mm ID and 0.17 ohms.
Same exact mod/TFR/preheat, same model of atty, same juice. The second one allowed me to get a comparable (if not stronger) vape at a lower temperature. I was getting a good vape at 415f on the 0.11 ohm coil, I got an equal or better vape off the 0.17 ohm coil at 360f.
I dont think it was so much the type of wire. I think it was because of the higher metal mass covering more of the surface area of the wick. The second one put more BTUs into the coil quicker generating more vapor at a lower temperature.
Just something to consider if you are trying to reduce your vape temp on a TC mod. More coil mass can help.
First, I can't believe this thread is still going, I though we had covered this to death already.
TC is about resistance change and the temperature set in itself is not the actual temperature but a setting of when to do they cut off... when the coil gets hotter, the variance is metered and once it hits the setting, the mod starts pulsing.
This is why that how the coil is built changes everything.
- Here's an example: You could have a coil that's 12 pressed wraps a certain gauge and set at 35W / 380F, and another coil that's exactly the same, but this time it's spaced, the wick is better done, so the coil is getting cooled a lot more, and so the ramp up being much longer at 35W / 380F, you'd feel like it's not as warmth, so you'd increase the temp instead of chain vaping long enough for the coil to heat up enough to reach that setting.
So the question is, if the coil is the same, why would you need to increase the Temp.? Easy, the coil is being cooled better by being distributed across more wick, to it's not getting as hot as the pressed one, plus the wicking done better would cool it more, so the variance in resistance isn't reached as easily, so more power is required.
- Here's another: Using different liquids and flavours, some are more fluid, some have a higher density, so they require more heat/power to evaporate as they have either a higher or lower cooling ratio, so you could have a tank with one liquid, then you refill with another, and have to increase or lower the temp to continue to have the same level of warmth.
So the question here is, if the temp setting was an absolute, the warmth level wouldn't change because of liquid use.
Also, when you play to adjust the TCR value of your build if you aren't happy with your vaping experience, this would disbalance everything should it be an absolute (the temp settings). But we change them to get the experience (warmth level) that we want.
So the only "real" temp. value to be concerned with is the warmth level that one likes... and unless you're tasting burnt, odds are that you're only hitting the vaporizing temp. of the liquid. And with pure VG having a flash point of 380F, PG being lower, then the odds of you ever getting truly above 380F is only through using too much wattage too fast and you'll burn something. Anything above a true 380F would probably serve to heat the air around it and provide the warmer aspect of it, but again, at that point, the actual difference between the flash point and the warmth achieved would be a minor differential. Between all this and the air cooling effect, the liquid never reaches the "worrisome" temps.
If anything, should one have the settings really way too high, it's an instant dry-hit as the sudden pulse of heat would instantly vaporize all the liquid close enough, and then actual creates a barrier that would push the liquid away from it (due to radiating that much heat), so no more wicking, no more cooling, and a tasteful burnt taste.
So as you're not stating if the coils are pressed or spaced, that the temp setting might be lower with one coil, but what about wattage fed? I know that some mods let you change the temp setting and adjust the wattage according the "low, normal, hard "hit"". But yes, more mass will usually result in more vapor produced, it's a question of balance between many factors.
Personally, I've yet to understand the whole uber-low ohm thing, as with adjusting to power and temp, I've yet to see much of a real difference between a 0.2 (or lower) to up to a 1ohm coil (or dual coil setup). I'd rather have a balanced setup that's wicking well, heats up fast enough and provides a good experience. I know that for cloud chasers it's about as much vapor produce per milli-second, but for the average person, that's not going to matter all that much.
