Bad luck since upgrading tanks...

[erikbal]

Here's the deal. I've been using an Atlantis V1 with an istick for a long time. A month or so ago I upgraded to a rx200 with a uwell crown. I really like this setup. I haven't had the best luck with coils though. I don't find I can run the .25s much higher than 60w or so. I keep finding they are just randomly starting to get dry hits and burnt hits for no reason.
This Thursday I got the smok tfv4 mini as a birthday gift. I primed up the .35 ohm coil and have been using it without issue, until last night. Out of nowhere I started getting burnt hits with this tank now around 70w. Well this morning I decided to try the triple coil I picked up for it. I primed it real good like normal and started out low with the wattage around 50 or so slowly increasing till about 65. Things were going fine then bam horrible burnt hit and now that's all I get. I'm going to try to sextuple coil now but why am I having such bad luck? I've been vaping for going on 3 years and I know how to prime coils and all. Just getting frustrated. I finally upgrade and have a setup Ii always wanted but keep getting frustrated!

The simpler single or dual coil set-ups can be swabbed out with a q-tip as long as the center bore of the coil is large enough. .2-.5ohm usually are. Some swabs are larger than others and a small amount of cotton may need to be removed so as they can be gently screwed in and out of the coil to remove the built up gunk.
Have been doing it every day or two when I notice the flavour changing, before getting a full on dry hit. Some coils last me months. I use high PG with min. flavour= minimum build-up.

Is this burnt hit happening in TC mode? You may wanna try ss, ni, or ti in temp mode to reduce this.

You may also consider taking longer draws at lower watts. ie. 40-50. Cheers.

Bummer. I feel for you. It can be expensive finding out where the 'sweet spot' is on a factory atomizer and the juice your using is. TFV4 atomizers are not cheap.

While the local B&M was telling me to expect a coil to last a week or two I was getting only a few days and sometimes only a few hours.

I simply gave up on factory wound atomizers and made the switch to RTA's and rarely look back. My builds last weeks or months rather than hours and days and I'm no longer chained to what I call the "atomizer tax" saving me oddles of $$$ in the process.

I'm going to try out the rba that came with the tfv4 mini. I'm not sure today will be a good day for that though as I may be away from home for hours and don't want to have to tinker with it all day. Also forgot to mention I bought an aspire cleito and haven't had the greatest luck with that either.

I would say your 60w is too high for the Crown, or you have some issue with the viscosity of your liquid or maybe a coil to tightly packed. I vape mine between 30-50w, use 3 tanks on different mods and never had a dry hit at all.
I go more for flavour with the Crown, maybe your more into clouds and the TFv4 would be better for that (i run mine 60-80w) its horses for courses imo

 

[erikbal]

See that's funny you say that because a friend of mine got the crown around the same time I did and he runs it around 90w all day long.

Once you build the RBA correctly you won't even bother with factory coil heads anymore , no tinkering will be necessary , i won't even buy a tank without a good RBA option .

This is why i left tanks for RDAs.

These coils are done by individual not computers.

Some coils have too little cotton. Causes pops and spitback.

Some coils have the cotton too tight and can't wick effectively. These you get Dry hits or burned wick.

What you need is an RDA or RTA and learn to rebuild so you can have consistency.

As mentioned, I think you might've over powered the crown coils. With the 0.25 and 0.5 coils I didn't find a need to significantly bump up the wattage, I believe I was around 35-45 for them both.

I tried the 1.2ohm (or was it 1.4) on the crown. At first around 20-30 for about 1 week. Then decided to try and bump it up to 40W one day and the coil went bad in a couple hours.

 

[Chasperk]

I have the TFV4 on an iStick tc100 (upgraded to 120 w) and consistently run 85-100 watts with no dry hits. Coils last about 3 weeks for me. Main thing I've learned with it is to not let the tank get to low on juice. I try to fill it before it gets to the last juice well of the coil.

Could also be the juice you are using. I'm using max VG. A blend may run different.

 

[OlderNDirt]

I have the TFV4 and two mini's and fortunately have not had any bad experiences. But, as Chasperk mentioned, I never let the tanks get very low. Since I change tanks/flavors pretty regular, it is rare I ever let the juice level get down below the top of the coil. Not saying that is or even could be the problem, just something to try. I normally run the kanthal coils around 68 to 78 watts.

I am also really liking the Ti coil, but have only run a couple flavors with it. I figure if it is working so well with those flavors, why change?

Good luck!

 

[erikbal]

Well here we go again. Today I was running the .4 ohm coil around 78 watts with no problems. Then I turn it back down to about 55 while I'm at work and once I got out and went to turn it back up I can barely go above 60w without burnt hits. Am I doing something wrong or am I just having awful luck with coils? I'd like to be able to use these tanks to their full potential.

if you're really experiencing issues with that high of a wattage why not tune it down and stay there? Prebuilt coils recommended wattage aren't set in stone. There is no point in trying to increase your wattage if your vape experience is suffering.

Higher Wattage does not equate to a better vape

ABSOLUTELY.

Just because the coils recommend a wattages range doesnt mean you have to go that high.

Start with a new coil and start LOW AND GRADUALLY work up until you find a wattage that works for you and that ejuice.

You need a satisfying vape not to use the highesr watts.

95% of my vaping is 12.5-17.5 watts; but one DIY Juice has a delicate flavor if i go higher than 10 watts.

Yes i have one Juice i vape at 8 pittling watts.

 

[rice721]

Just to give a better perspective.

I build my own coils. Right now I'm staring at a dual clapton 26/32 8 wrap 3.0mm IAD 0.48ohm build in an Aromamizer Supreme. My boxer SX350J V2 is reading 55 Watts and the vape is wonderful.

I've built a quad clapton coil 26/32 7-8 wrap 2.5mm IAD 0.25ohm in the iJoy tornado. I vaped that thing at around 60-70 watts and I did not enjoy it as much as I did with the aforementioned one.

 

[erikbal]

Ok so you're saying it's normal to not be able to run these coils at wattages that tons of other people run at and I should just accept the fact that I can't get near the full potential out of these tanks? I understand the ratings are just suggestions but when a coil is rated to 130 and I'm getting burnt hits at 60, less than half, something isn't right

no not saying its normal or what you're doing is wrong. Did a quick look both the triple and quad coils are rated at 40W-120 and 40W - 130 respectively (according to vaping360 dot coms review).

130 is the high end.

What we are saying is full potential does not equal to the maximum wattage a coil can take. The full potential of any prebuilt or even self made coil is the wattage that provides you the best vape, whether its at the low end, high end or somewhere in between of a given suggested spectrum (usually for prebuilts). I don't think you should stress that your prebuilt coils aren't able to take more power instead you should focus on what power gives you the vape you want. If 60W results in burnt hits after chain vaping then lower the wattage and go from there.

You mentioned earlier that you seemed to settle at a wattage that you found gave you this "full potential", but you seem to want to push these coil heads to their limits.

There is no upper limit to how much heat a coil puts out in power mode. Your wattage made be stagnant at 60W, but the longer you fire that button the hotter the coil is going to get until the timer restriction (usually 10 secs on reg mods) kicks in. So depending on how long your draw is you might be pushing the coil to too high of a temperature, causing burnt hits.

If you really want to be able to hit that 130W chain vaping daily then I would suggest going the rebuildable route and tinkering from there.

 

[Jdurand]

I can't help with your issue, but I will say +1 on the RTA route. I gave up on inconsistent factory coils. They are too darn expensive and unreliable for my taste. Cotton and wire are cheap and will be available no matter what the future brings. Can't say that about factory coils anymore. You may wish to stop with trying to dial in those coils and start to learn rebuilding instead.

 

[GeorgeS]

I had the same issue with Nautilus coils. While 'everyone' was claiming the 'sweet spot' for those coils is 13W, I was getting dry hits anywhere over 10W, I ended up ignoring whatever 'everybody else' was doing and happy vaped away at 8-10W.

The TFV4 is one of my favorite tanks. Frankly I've never used the factory coils. I've instead used both the "R1" and "R2" (I prefer the "R1").

My current build 0.98ohms of NiFe48 flat ribbon 30AWG - single coil is being fired at 25W in TC mode. Perfect for my uses. I can fill my lungs easily enough on a draw and can chain vape it all day if I wish.

While many figure the TFV4 is designed and built for cloud chucking high power (>80W) performance, it can also be used for lessor results that are satisfying depending on what your goals are.
