Wire safe duration

[tj99959]

I suppose I could rinse them out/dry burn and get another week/month out of a coil .... but WHY?!?
There isn't a dimes worth of material in a coil, so when mine get junked up I just wrap a new one.

I've been doing a test with Kanthal.
Have a Kanthal coil sitting in a vial of water.
4 weeks...so far NO rust ???

It rusts here. If it is annealed, it won't. But once the wire starts cracking from dry burning, it will rust again.

Ikr seems odd to me to rust like even if it rust into water I guess while vaping it and using it why would it rust....

Because of the tiny amount of water in juices and PG/VG sucks up moisture from the air like a sponge.

I can't remember in what thread and who was that said it but had a pic of a coil also that was brownish and to me didn't seem like rust but then again I just saw a pic so I can't be sure and I didn't bother do any experiment to see....and then i got nichrome and stainless on my wires purchase hahaha

Both Nichrome and SS taste like metal to me. And it gets worse after dry burning. Kanthal taste ok until it rusts. Then it tastes like iron. And Ni200 tastes fine to me for some reason.

Question: the coils on the atty that got rust on them....did this happend while vaping it or while vaping it and then left for few days without getting vaped? I mean is there any way to avoid the rusting maybe if we use it all the time?

 

[BillW50]

It happens while vaping on it. Usually once the coil has been dry burned. You should start tasting iron first before you can see it. If they are annealed and don't crack, they shouldn't rust.

Have a vague memory of @Rossum looking at his single wire builds up close to judge degradation.

I mostly use 3x30 twisted Kanthal coils. Yeah, I look at 'em under some magnification after I dry-burn and clean 'em. But none of that happens very often because my ADV is straight unflavored (65VG/35PG/12N) and I use rayon wicking. In fact, I just dry burned and re-wicked my ADV atty a couple of days ago 'cause it was starting to produce a burnt taste. The coil itself was last replaced on 2019-10-06, and this is the 5th dry burn & wick since then. I might replace it the next time.

Yes, I keep a log.

Well I did say it was a vague memory, thanks Rossum.

Recently I got a very soft metallic brush to clean on rewicks and still do it with care cause I feel like they gonna be scratched very easily and won't be visible with naked eye...

I found a bag of small, nylon (I believe), cylindrical dental brushes that are just smaller than the inside ofmy coil that I am using for cleaning inside and out. These are rather soft and, if I remember to let the coil cool before using, work rather well. (Yes, I really did.)

Walmart has an "Equate" brand that are inexpensive.

I use a piece of pipe cleaner, cut down to about 4" in length, and wet. That way I can pulse the coil while brushing the inside.

Because I use a very sweet juice, am semi-retired so I have time on my hands, and 100 ft of kanthal wire costs $6.58, I change my coil weekly.

~~~Hey, big spender ................

I use pipe cleaners too, but I never heated the coils. As I don't know the material the pipe cleaner is made out with. And I suppose not all of them are made from the same materials. But being wet, the coil is going to drop in temperature really fast anyway.

I never knew they made pipe cleaners that don't burn. I have an old pack of Dill's pipe cleaners and I'm pretty sure they would burn - they're made of cotton.

This is exactly what I have...

 

[BillW50]

These are what I use. I don't believe these are cotton. They are probably nylon.

Why doesn't a cotton wick burn? Because it's wet. Let me re-emphasize: I use a wet pipe-cleaner.

I've re-wicked the same Steam Crave Tri Core Fused Clapton Coil I started with when I got my Aromamizer Supreme V3 RDTA three times now and under a magnifying glass it still looks New. New as in not gunked up or nasty. Same with the Dual Coils I built with Temcoindustrial.com's Kanthal A1 wire, just like new. I don't use Flavor in the Steam Crave Tank though so I'm sure that helps. When it looks worn out I guess you'd say I'll install a new one. I wouldn't want Metal particles in my lungs at any point but I see nothing alarming so far. My thoughts are the type of liquid used leads to the fastest degradation. Some have almost no effect at all, some degrade a Coil fast.
