GS Tank TC - Eleaf Istick 40W: Inconsistent draws

[QuiKonJinn]

Good evening people. I started vaping somewhere at the end of last august with a nunchaku vapros - v-spot combo, after a couple different atomizers moved to eleaf istick 40W and GS tank with TC 0.15 ohm coils. And here's my problem.
Sometimes right after cleaning it (wiping everything inside and the liquid from the top of the coil - not inside the coil) I'm getting huge draws for the first minute or so, with a tiny bit of gargling nothing annoying though. Most of the time however, even after cleaning it I get draws that seem a bit lackluster in both taste and vapour. Got any advice maybe something I am overlooking or might not know about?
vaping at around 270 degrees celcius and when I'm getting these big draws I talked about they're a bit too hot, however the rest of the time (lackluster draws) 270 degrees seem not enough and the only reason I don't crank it up is for battery life.
I think the problem is when there is liquid on the rubber ring on top of the coil, unfortunately I can't seem to stop liquid from accumulating there.

Sorry, can't help you, but does it clear up and start vaping again?

welcome to ecf, jinn

not sure what might be going on but quite a few of us have found the tc coil performance inconsistent stop by here with your question
Eleaf GS Air Fan : Part 2
maybe somebody there who got that coil working properly will have an answer for you!

It vapes good enough, but no the problem doesn't go away until I open it up and wipe it clean again.

Thank you very much Tibs .
I'll check out that thread.

I have had them where I've had to blow back into the drip tip to cure the gurgling, but haven't experienced the inconsistent draw. I'm Vaping at almost the exact same temperature as you are 520F. I have had good success with the ones I've recoiled and rewicked also.

That's interesting. I've been thinking maybe it's a flawed part. Gonna look into that thank you.

1-First ensure that you are locking the coil resistance at room temperature.
2-Remove drip tip and set tank upside down for about 2 minutes.
3-Remove base and remove coil from base.
4-Wrap the coil in a square of toilet paper.
5-Use a TP square to clean down inside base.
6- Get a Q-Tip and remove most of the cotton so it will slide inside chimney. Clean chimney.
7-Unwrap coil from TP, cup it with the TP, and blow firmly into top of coil so juice comes out the bottom of coil into the TP.
8-Repeat step 7.
9-Turn the temp up to 300F.

TL;DR:

Clean the f*** out of everything.
Turn up heat so juice vaporizes and doesn't flood.

Hope this helps.

For what it may be worth...

Disclaimers:
(1) I am a novice with TC devices, having tried it only with the istick 40
and the same tc coils you use.
(2) I do not have any other TC mod, so I can't tell if the problems are
caused by the coils, the mod, or both.
(3) The istick 40 performs very nicely in vv/vw mode with other eleaf coils.

I have tried about half a dozen tc coils. Two have been consistently pretty good, not great. With the others, vapor is inconsistent. Constant adjustments to temperature are needed to get decent flavor and vapor volume. My target temperature range is 480-520°F. Sometimes I have to increase tmp. a lot to get any vapor at all, then suddenly get a very hot vape, and back it down. At the moment, I'm at 570°F, and getting an agreeable, but not especially abundant, amount of vapor and flavor. I have some of the same juice, 30/70 pg/vg, 6mg nic., in a GS Air M on an istick 30. That is giving much more vapor and flavor at 8.4 watts.

I suspect that the coils are the problem, but other people have reported better results with the same tanks and coils on different TC devices. The TC vape is softer, smoother, and has a more muted flavor than with vv/vw gear. That would be ok for me at times, but the inconsistent results are frustrating.

That is more or less what I've been doing, and I'm getting really rich puffs for about a minute or less. After that it goes back to it's regular draws. And even after I've done all that you mentioned sometimes nothing changes. It's inconsistent in it's inconsistency. I'm probably missing something and being a noob.

I'm gonna post a picture of the accumulating liquid in the morning when the light is better.

I think we're having the exact same issue. I'm at my 3rd or 4th coil, but what you mention about having to change temps and get it higher to be able to enjoy it is exactly what I've been doing since getting it. Have you noticed better draws after cleaning the excess liquid from the metal ring at the end of the chimney?

I routinely clean everything when I add juice to any tank. That includes removing coils and cleaning the cavity where the coil screws into the base. I also swab out chimneys and the place where the drip tip plugs in. None of that seems related to the inconsistent vapes with tc coils. I believe, without hard proof, that either the coils themselves are (a) badly designed or (b) manufactured without sufficient quality control, or both. Our esteemed colleague and master re-coiler Cheechako described it much more succintly: "Crap coils." The tc logic board in the istick 40 may exacerbate the coil issues. Or not.

Here is my usual solution: Put the tc coils in the 'spares box', where unloved vape gear
gathers dust until somebody on the forum or a local vaper needs it. Replace the tc coil with an eleaf 1.5 ohm dual coil, and be a happy vaper.

If you enjoy swapping one aggravation for another, swap to the eleaf 1.2 ohm "organic" (Proof, please!) cotton wick coil. Keep your watts and volts low to start, and ramp up slowly. Enjoy happy vaping for a day or two, then sputter and curse when the oversaturated coil gurgles, sputters, and makes you think unkind thoughts.

Haha alright I just might try the 1.5. That's the standard non-TC coil that comes with the GS Air atomizer right?

This is wise advice!

You are correct sir! It is a proven coil with minimal troubles. It has a reputation for lasting a long time and delivering a very satisfying vape.
I won't get into how a recoiled Air coil is a slice of fried gold!
That is one of the nice things about the GS line, flexibility of coils and tanks.
As had been suggested above, the void beneath the drip tip on the tank tends to accumulate juice. Sooner or later it will run down the air tube and
surprise, a bit of flooding.
The TC coils have a very spotty reputation on the 40 watt TC but have been praised on other TC devices. Not worth buying another mod for.
Good luck and keep us posted!

Alright so after a full day of vaping with the 1.5 ohm dual coil (look at me using your guys' fancy terms like I know what I'm talking about) I am reporting back. Rich taste, nice throat hits, and even though it needs a little bit of priming, every draw is the same as the last. So to sum up, we've narrowed down the problem to crap coils, and/or TC not being the best vaping method on the istick 40W.
Thank all of you so much for your responses. I'm gonna tag the .... out of this thread to make it easy for other people to find.

Edit: Or just do the 3 tag limit :/

Am glad it started to work for you.
It is my favourite tank- so far
the nickel coil spits on the first drag from cold.
(I've been using Evic mini on its straight Nickel setting.
I have my dripper on the Evic most of the time, so I can't remember the GS Tank settings...
4 drags & I'm in nic OD territory...lol)
