How long should your builds (coils) last? Ok to dry fire them?

[Two_Bears]

I vape sweet juices like marshmallow man and loaded donuts currently. Here's a pic from the coils I cleaned last night what a joke lol

I like sweet flavors too but Ive had my coil Wicked with Rayon and vaped for two weeks and never looked anything like that

Are you getting a burnt or scorched taste? The discoloration is likely due to the type and amount of sweetener in the juice. Most retail e-juice has low to moderate amounts (0.2 - 0.7%) of sucralose based sweeteners added as a flavor/body enhancer, some have high amounts (>1.5%) added for extreme sweetness (candy like). The more sweetener used the faster coils will gunk up. Could also be you're firing your coils at too high a wattage for the juice you're using. Some juice can't handle low ohms and high watts.

Im at 0.17 ohm watts ranging from 100-115 volts at 4.2-4.4

What is Rayon?

Looking at that as one day of deposit, I'd have to agree with everyone, you're using the wrong juice on the wrong build. My coils have never looked like that, even ones I've been lazy about caring for. I can't even figure how you could even clean that up.

Wrong juice on wrong build on.... interesting I didn't know certain juices went with certain juices, neither do the guys that work at my vape shop.. So what type of build should I have? they work fine on my dripper that came with my kangertech drip box, it seems to be just on the velocity v2 that I am having this issue!

No I didn't get a burnt taste just before changing them I could taste a faint burning taste.

I don't build lower than 0.4 ohms so my thoughts are just speculation but I'd guess the rapid discoloration on your coils is the sweetener from the juice scorching. All of the popular sweeteners are unstable at high temperatures which is why they're hard on coils. You could try lowering your watts or switch to a different juice and see if that helps.

Low builds (higher wattage) mean not higher temperatures but higher volumes of juice being vaporized. Higher juice consumption = faster gunk accumulation.

You could also go with a simple coil build if you want to stay with a sweet juice. They will gunk as well, but are far easier, IME, to clean up than an complex fused Clapton type setup. Not to sound like an English muffin commercial, but this is where all those nooks and crannies don't do you any favors on gunk buildup. They also can be run at lower power, less juice consumption, less mess.

Still, it's not just your coils all gunked, your cotton is really a mess for one day accumulation. When I change my wick, the part in contact with the coil will be fairly dark, but the tails are a mild brownish at worst. I've never had a whole wick turn black on me.

I wanna expand on that a little, less power usually means longer battery life!
I have gone back to standard spaced and use much less power, easier to clean and longer runs between charges.
To each their own bit I've started back to flavor over clouds and there are many benefits.
Also my juice consumption is going down as I try to find my sweet spot so there is another benefit.

Here are some coils (wicked with Rayon, DIY juice with little/no sweetener) I changed recently after about a month and guesstimating 100 - 150 ml of juice (I have 4 rda/rta/rdta in daily rotation):

- Boreas - 06Oct dual 0.45 fused clapton = ~0.21, wicked 25Oct, 22Nov, 20Dec

I will probably replace the coils next time I wick in late January since I have already dry burned/cleaned them 3 times now.

edit to add: precoiled kanthal running in power mode @ 75w with 90w preheat for 0.7s

Its funny it only happens when I buy these fancy pre made coils! When I do them myself I get a solid week week and a half out of them and I'm ok with that. They even last longer I find when you clean them as well.

Those are pretty dark and gunky but the wick is good !

Rayon is synthetic fibers usually found at Sally's beauty supply. It was made to use for during hair abd hair permanents.

The fibers last a LOT longer than cotton.

With cotton i have to rewick every 6-10/mls. With Rayon i wick about every two weeks about every 55-60 mls of Juice.

Some ECF members are able to vape 100+ mls on one set of wicks.

Rayon shrinks with ejuice so the wick needs to be much tighter than cotton wicks.

But it wicks Juice like crazy

And the tails usually need to be thinned/trimmed a LOT

I got the rayon I pictured above via Amazon. If you're used to using cotton bacon it's just like that. Except as mentioned you gotta make the wick tight at the coil and snipped at the tails.

I tried rayon, but it seemed to burn at the same settings as my Japanese cotton.
It would be turned brown in the coil within an hour or two.
Could just be the rayon I had, didn't seem to wick well enough.

 

[Two_Bears]

Correct. The more you thin the tails TGS better it wicks.

Thin the tails about 40%. Fantastic wick.

I really like Rayon in attys with large Juice wells. Kayfun Monster V3
Silverplay Nano
SXK Nebula Wine
Goblin Mini.

Simple round wire coils that are spaced

Tight wick till it squeaks then thin the tails about 30-40% and it will wick amazing.
