Series of short puffs instead of long draw to avoid burnt taste

[trying]

Temperature control of coarse is designed to prevent the coil from getting hot enough to burn the e-liquid but an other consideration is how long the liquid is in contact with the hot coil.

No matter what the TC setting is the e-liquid is much less likely to burn if it is only in contact with the coil for a second vs 5 or 6 seconds for a deep draw.

As long as you have enough juice flow and air flow, burn is unlikely. With TC as long as the temperature is below the burn level of the wick material it should not burn either.

Um, I think with decent TC, the length of the draw shouldn't impact things that much. If you are worried, you could always just dial in your overall temperature lower, I'd think. The whole point of TC is that if things are getting unduly hot, the mod will handle that situation for you. With that said, if short puffs make you more comfortable, there's no reason NOT to do it, except given your ramp up time and mass of the coil, you may actually need a longer draw than a half-second to get things going.... I just think if you've made it to TC and are using it properly, you shouldn't really have to worry about the length of the draw, though a times, you may not get vape for that entire time if the temp does rise too high? I haven't really experimented with "draw length" yet but I find using my regular draw works perfectly fine....

My solution was more along the lines of you have done everything correctly.
It's just for some unknown reason your getting a burnt taste.
At that point try shorter of shallower puffs verse your normal draw and the burnt taste should go away.
I have had times when the same setting with the same liquid that never produced a burnt taste before for some reason does produce a burnt taste.

Okay, I've never had a situation where I've gotten a burnt taste where it wasn't the coil, and usually the tankful of juice that came with it. To be fair, I vape at extremely low wattage, but the only time I've toasted a coil past what's usual for me, I've misused my equipment in some way, for example not knowing that my steampunk will go down to 7 watts ONLY, then spin around to 120 watts. That was the worst burnt hit I've ever had, LOL. But I haven't been in a situation when juice tastes weird but then it goes away. I'm not going to say it never happens, I just have never had that situation, so I guess I'm glad you found a solution? I could see juice getting a bit overheated on a wick at high temps, I guess....??? But, kind of the point of TC is that DOESN'T happen. What settings are you using and with what equipment? I'm just curious at this point....

Turn the power down!!!

I prefer to cover the air hole and do a primer puff till it gurgles then crank the wattage up. At 7.5w it is already too low for short puffs or to turn the power down even moreso.

Its all about wicking. If I could`nt take a long draw, I probably wouldn't be vaping. Your work around may be OK with a lung hitter, but I am a high power MTL hitter, so its like 4-5 second draws for me. If the wicking is good, the juice will flow to the coil and cool it down. If the flow is not able to keep up due to a tight wick, that`s when it gets hot b/c the coils are not being cooled down by a constant juice flow.

BOL.

I've had both burnt hits and what I call "warning hits," which aren't bad enough to scorch the wick beyond further use, but bad tasting enough to let me know that the sweet spot was a few Watts ago. Or in TC mode, bad enough to let me know that either temp is set too high and/or there's too much initial power.

TC does what the OP is describing. The mod reads the resistance change, calculates temperature and knocks the power down until the coil

If you are getting a burnt taste there is only one possible answer: the coil is getting hot enough to burn the juice. This should never happen with a properly set (and properly functioning) TC setup. If you are trying to get more vapor by setting the temperature too high, short puffs may be the only way to prevent a burn, but that isn't TC. That's just what you have to do with a normal high Wattage setup with insufficient juice feed. You are stopping the power before your coil is getting up to the temperature you have your mod set to (or that it can reach if the mod is malfunctioning). Some mods "remember" the cold resistance of the coil and can be "fooled" if you first fire them with a warm coil. If so, you may be reaching higher temps than you think your TC mod is set for.

With TC, if you want more vapor, you need to be using a coil with more surface area, not a higher temperature. You may need to graduate to "Clapton" type coils, or even some of the more elaborate styles with huge surface areas.

Note that I only vape for the nicotine. Rather than trying for more vapor, I have just increased the strength of my juice. My TC rigs are set to 425˚F (225˚C). For comparison, my non-TC rigs are set to only 8 or 9 Watts. OTOH, my DIY juice is 65 mg/ml (6.5%), so I get enough nicotine with very little vapor. (And very few puffs.)

One thing is not to take short hits, but release the power button for 1/2 second and then keep going. I more use this on pen vapes where there is limited control, but it really is kind of optimum as long as the first hit can handle 4-5 seconds on the first pulse (something you have to pump the button constantly is just too hot) and 3 seconds thereafter. This also resets the hit timer so now you can go on indefinitely . Each pulse I can taste a progression from cool through good to slightly hot and dry.

If I could`nt take a long draw, I probably wouldn't be vaping.

ditto. I can take a full 10 second pull if I want (if my asthmatic lungs are capable of DLing that much vapor) on all 7 of my TC setups I have in rotation. They all use SS wire in the 0.15 - 0.25 ohm range with preheat watts set from 55 to 85+ watts.
