Fusion LR issues/lifespan?

[CrazyIvan]

Hi,

I'm fairly new to carto tanks so bear with me. I recently switched from clearos to carto tanks and for my second set of carto's I decided to go with the IKV Fusion LRs. So, first thing I noticed, the five I bought ranged from 1.5 ohm to 1.7 ohm. I was under the impression that they were supposed to be 2.0 ohm (+- .2). Anyway, no biggie, I tried one and LOVED IT! Very good flavor/vapor/TH with these! Almost too much TH actually, which is great since I can't remmeber last time I had good TH. But after 2-3 days, the flavor started fading, I noticed slight gurgle (no leaks) and on day 3 the resistance suddenly dropped from 1.7 ohm to 1.1 ohm. Since my Vamo won't drive anything under 1.2, it's done. Now I'm onto the second one (this is day 3), and again the carto started out really nice. I'm hoping it will last longer tho. Any experiences with this? Or am I doing something wrong?

P.S. The juice I use is 18mg 80/20 mix and I vape @ 3.1 volt.

I just started using the 510 Mega Fusion (3.0ohm), and the only issue I had was priming it. Once I got past that, the thing has been stellar!

I'm right at seven days on the carto, and I've put 25ml's of Halo SubZero through it (really potent menthol). It still hits as good as it did brand new. Previously, I'd consider it a good run to get 15ml's through a different brand.

I vape at right around 10w (5.5v at this resistance). If you're getting a gurgle, I would suspect your vape is too cool, and over-wicking, causing the coil to get gunked up and fail. Perhaps try kicking your voltage up to 4v or so and see if it improves.

The reason for gurgling is too much juice. Tanks work on a vacuum system. If any air gets in juice comes out. If you take the tank off and plug the battery end with your finger. Then draw very hard (with a full tank) you will see air bubbles were the leak is. Another reason for flooding is if you punch too deep and pierce the inner tube on the carto itself. I hope this helps. Most of us have gone through it at one time or another. Also my pv went off in my pocket the other day and got very, very hot. When it cooled down I noticed gurgling until it stopped.

Thanks for the replies. I'm not as concerned about the gurgle as I am about it quitting on me after 3 days. Hopefully it was a fluke and the others will be ok.

Rob, I've tried dialing up but I am not able to go above 3.3 volt on these, I just end up with a burning taste. Probably due to the lower than expected resistance on them. If these don't work out, I may try the 3 ohm next. Seems like I may have more dialing flexibility with those.

I assume nobody has an explanation about the sudden ohm drop?

 

[KY_Rob]

Sudden drop in resistance is usually an indication of a coil short...that usually just results in carto death.

Well, guess what? I decided to try and wash out the carto, I did so with just hot running water and blowing through it. I then tested the resistance and still 1.1 ohm. Then I let it dry overnight and the next morning, BAM - 1.6 again. I filled it with juice and it vapes like new again!!! I am not sure what happened but my "working theory" is that I somehow flooded the contacts enough to make some of the charge run through the conductive liquid in addition to the coil. That would account for the drop in resistance. I am not sure if that's a feasible explanation, but whatever, I am back to vaping happily!

I am also getting better at proper vaping with a carto tank (slower draws), so hopefully that will avoid future flooding. I am used to stardust-style clearos and those usually have a tight draw, so cartos required a technique adjustment on my part.

Just wanted to give an update. Thanks!

It is. We found out a few yrs. ago that juice is conductive and some more than others. It puts lead in your pencil.

Well, I spoke too soon. The carto ended up lasting for about half a day and then started tasting very muted again. The On top of that, the second one I tried also lost its taste after about a day. Neither of them had a resistance drop off like before, but they just lost all taste. As I said before, neither of these I could ever fire at above 3.3 volt or so, or they would taste burned. I usually ran them at 3.0 or 3.1, trying to adjust as needed.

My lack of experience with cartos in general led me to believe that it was normal, but now I tried a third one, filled it the same way, vaped it the same way, and it's no comparrison!!! From the start, this one vapes like a dream at 3.7-3.8 volt. Same ohm rating. The flavor is twice as good as the first two, and I don't have to constantly fiddle with the voltage to make it right. The third one just works and works well from the start.

I also unpacked the last 2 (not sure if I should have, hopefully they won't dry out or something), and one of them tests at 0.0 ohm. I noticed the base pin seems offset and touching the outer ring, so maybe that's the issue.

Anyway, I'm still not sure if I did something wrong with these due to lack of experience or I got some bad ones. The only cartos I had before this were chinese ones that came with my tanks and they flooded constantly. I kept the two "bad ones" and may try to fiddle with them some more to determine what the culprit was.

At least on the PVs I use, I tend to stick with 2.5 ohms, I've found they tend to work well with VV/VW devices. On 801 fusions and 510 platinums I can count on about 20 ml of eliquid through them before it's time to swap, using the particular eliquid I've vaped for years; I'm sure I could get more run time, but I'm both lazy and picky -- I swap as soon as the flavor goes slightly off, cartos are disposable. Isaac's are the only cartos I've used in quite a long time -- very consistent for me, good QC (though as with anything, once in a while something can slip through -- the joys of manufacturing).

I'm on day 10 of the very first mega fusion punch 3.0...I've put close to 35ml's of SubZero through it...and it STILL acts like its new.

I'm driving it on a ProVari v2.5 @5.3v. Don't know how much that has to do with it, but the very smooth PWM likely plays some role...

I remember back when the Provari first released. All V1 models were destroying resistant decimals by the hour. There are many different factors with currents and their reactions like liquid, batteries, power source, and atty/carto coils. While the Provari was a godsend, it also spiked a huge popularity for mechanical mods which ofcourse revealed their own downsides.Then other makers upped the game with better circuitry to alleviate this problem. I do have one other customer that suffering from this problem with a V2. I advised her to speak with Phil at Provape so he can inspect the unit for any shorts. If this was a wide spread problem. I'll be first in line to take action. I'll report back with findings.

That's why I use the Buzz Pro from the originator of VVPVs. I don't suffer those problems unless there is a short. But I use them only with Ikenvape atty's/cartos for the same reason. They are the best.

I consistently get an average of 4 days per carto with tanked 801 Fusions and 510 Fusions. Sometimes 2 days, sometimes 6. But usually 4. They don't die outright, but they get very tight and the vapor production drops to almost nil. This is with juices that are 70/30. I just don't get the longevity that other people do, but it doesn't bother me because they are so good otherwise.

Your Vaping style, the juice, and the voltage all come into play. I've went through a box of 5 in 5 days (only once) and I've gotten almost 2 mo. out of fusions but 2 weeks is my norm. I use 100% PG or close to that ratio and they are all pretty light in color.
