HV atties rapidly dropping resistance ...?

[Wacky Dee]

My IKV 510HV atties appear to have dropped resistance from 3.5Ohms after 2 weeks of use on a Buzz (at 4.5V) to 3.0 Ohms.

Now after a day of use at 5.4Volts on my new Provari, they've dropped to 2 and 2.4 Ohms. Does anyone know if this is normal ie. for the atties to be dropping their resistance due to high voltage/wattage use ?? I always thought resistance would increase if the atties were slowly dying..

Here's one explanation:

I'm very interested in hearing this answer too. I thought I was the only one this happened to. I just usually lower voltage on ProVari to compensate, but never understood why it's happening.

I think different juices can get that coil gunked up quicker than others but I am gonnna leave my postt at that to allow someone with more knowledge to comment.

 

[Wacky Dee]

Yeah I understand the gunk stuff ..but that's supposed to INCREASE the resistance overall not decrease like what's happening here..

I think Scottbee has your answer. Switched is also an atty guy and may know.

 

[Wacky Dee]

so one or more adjacent coils in the heating element fused together ? in both atties ? Hm might try Joye HV atties next instead of Ikenvapes. I won't say it's a problem with the IKV HV atties because I'm sure a lot of other people use them and if there was a general problem with them fusing coils at high voltages other ppl would also have reported these issues by now

I have read a few different places that for some reason it drops the resistance but it was just that"reading" never confirmed that. Have you ever tried the baking soda vinegar cleaning trick. It might be worth a shot, put a bit of baking soda in the atty and then puta bit of vinegar in and cover the top and allow the pressure to go out the bottom hole, do this until there is no longer a reaction and I repeat it several times depending on what flavor I had in the atty. This has been great for cleaning atties for me and dont worry about tasting vinegar because for some reason the baking soda neutralizes the vinegar and with a quick rinse of water I have not tasted vinegar yet. Not saying it will work but might be worth a shot

I've already soaked them in pure rubbing alcohol which turned from clear to yellow after 10 mins or so. After drying and priming ..still the same, actually resistance dropped even further.

I'd really like to do a post mortem on one of these atties to find out what really happened to the coiled wired.

 

[Wacky Dee]

update: out of desperation i did a really long dry burn on the cleaned atty (which was showing 1.9 ohms) and it went back up to 3.3 - 3.5

Let's see how long it lasts before it drops below 3.0 ohms now..

Scottbee is the man I would ask. Although I have a general knowledge of electricity, there are many facets that elude me, this being one of them.

Hey Wacky
Did you ever get my message?


Good morning XXXX,
I actually have the same exact problem with the Provari I have been monitoring my atties when using them and they seem to drop with E1 and E2 error codes. I Know the atomizers are not dead, and I constantly have to lower the voltage by the decimal point, very aggravating to say the least.I tested the atoms with 2 meters reading 3.4Ω then back on the Provari and receive 2.8 through 3.0. Switched and I have a daily lunch video chat on skype and he has been witnessing this. I ran 2 306 atoms with the same alternating problems. We're trying to figure out exactly why this happening as the problems never occur on my Buzz. At first I believed it was a variable voltage problem, but the Buzz confirms otherwise. You'll notice, if you swap out you're batteries or even reboot your ProV (unwind the cap, then screw it back on) you should have different numbers. Do you have a meter lying around the house to help me verify this problem as I want to know without shedding any negative light for both parties on this problem.
Sincerely,
Isaac

Scratch that, reading your reply

Isaac, thought i'd let you know that I agree with you., and I appreciate you chiming in here. As I posted earlier in this thread that my atty's were dropping in ohms also when used on my ProVari. The issue also for me was when I use fusions on it, there is no decrease in ohms and I get battery life up to 3.6 before light flashes. Now here's the interesting part, when I use HV attys(306 and 510) resistance drops dramatically(to much to be juice buildup) and light flashes as early as 3.9! I don't understand it. I sent it in to see if they could find a problem, it will be here in a day or so, and again I will put it through it's paces. Now ProVari fans don't get me wrong, the Provari is my favorite PV and I hope this issue will be resolved. For some reason HV atty's play tricks on the micro processor or something.

 

[Wacky Dee]

As my last IKV 510HV atty has dropped down to 2Ohm (confirmed with multi-meter) I've started using a SLB 510HV (2.8Ohm) which is now after a day of use showing 3.1 Ohms on the Provari. Just perfect for 5.5V vaping.

Still early days but it will be interesting to see if it also drops resistance in a couple of weeks of use. If it doesn't, then we know the issue is with the IKV atties.

 

[Wacky Dee]

Oh and in regards to the ligh flashing on the Provari ... I found that way too annoying so turned it off. It will still 'flash' when it's REALLY time to change the battery which is good enough. I think the Provari has over-discharge protection so the early flashing/reminder is rather pointless.

 

[Vaporologist]

I don't want to derail this thread but some of these premature flashing "problems" with ProVari were discussed in a specific thread and the solution turned out to be a simple one: cleaning and maintenance. Hope this helps.

I've read that thread.. unfortunately nothing to do with this issue.
