Aerotank coils, a little questions

[Q]

Not really a troubleshoot, more of an ask to see if anyone knows why?

My aerotank coils have been lasting VERY well, but I decided to replace one last night that was getting a little 'clogged', well this morning my juices had hardly any flavour & I was getting very little vapour, checked the coil 1.5ohm as normal, cleaned it, put it back, but it hadn't improved.
I was just about to condemn my latest juice to the 'dont bother' box when I decided to change the coil again, still 1.5ohm from the same packet and its fine, swapped them back again & noticed that the previous coil was taking an age to heat up.
Now surely if they are both 1.5ohm and tried on the same mvp they should heat up similar to each other, or am I missing something obvious?
Anyway the (last nights) new coil has been put in the 'must try recoiling these one day' box and I'm vaping happy again, but why did this happen?

Hmm, can't help you there Q, apart from saying that factory coils are notoriously inconsistent. I have had the same with Protank1 heads, and they too have been recoiled and now work perfectly.
Incidentally, I posted about this recently but didn't get a really satisfactory answer (probably due to the badly-worded question!). When you recoil a PT3 head, do you put in a single microcoil? If so, how do you fill out the discrepancy in the head itself? Do you put in a CW flavour wick, or don't you bother?
I want to recoil them as I'm a skinflint, but don't want RA leaking all over my wife's new twinset and pearls!

Tell her to vape naked

Most people use single coil heads (easy to recoil) and mess around with the plastic cap thingys to make them fit the dual coil. You can put a "flavour wick" in the dual coil head, but there are mixed reports of success. I think Jonco and naturevape have found simple fixes to turn a single coil head into a dual coil size, some kind of spacer I think, but I haven't tried either.

In the gladius heads I have been recoiling which are very similar to the kanger dual coils, but the chimney bit is shorter, I've been flavour wicking the gap without problems.

thinkingsmileyI'm mostly recoiling them for hubby .... maybe I should do it wrong to get his kit off

Been recoiling my dual ones as singles for a few weeks and adding either a few strands of silica or a bit of cotton depending on the build and they're working great. Much better than the originals. The cotton seems to give out better flavour and vapour but that could just be down to wishful thinking compared to the prewicked silica ones I also coil as I got a selection of each from fasttech. The original single pt2 silica ones have a strand or two of silica on top direct from kanger so I just copied them

[Q]

We've now got 2 answers on the recoiling side (which I didn't ask) but not one answer to my original question, apart from chykensas suggestion...

Does anyone know of any reason for a 1.5ohm (tested) coil taking an age to heat up?

I doubt it but maybe it's fitted with thicker coil, i.e 0.3 not 0.15......more than likely a bad coil somewhere along the lines.

I don't know the reason in your ones case. But I daily use kanger aerotanks and buy the 2 ohm dual coils. I buy the boxes of 5 as its cheaper. Often I find one in the box has problems. Sometimes dead or not firing well or slow. I guess its just down to quality control. I just put it in the collection box and replace with a new one.

Not much help, sorry.

Just an assumption, given the different resistances available.

Could be that they were assembling heads for a different resistance, but when tested they came out @ 1.5 ohm and were binned and packaged as such?

My take on your question Q is although it might glow when dry burned etc, if it's an old one that has been used for a little while then simply put, the coil has probably reached the end of it's life as the wire degrades over time. If it was a relatively new coil then it is most probably defective and coiled badly.

[Q]

It was a brand new one (proper, not clone) #2 from a pack of 5, #1 was fine and I've replaced it with #3 which is also fine, all read 1.5ohm it just takes around 4 seconds to heat up

[Deleted]

The others fine from same pack on same mod = duff one!

edit to add to explain. As I mentioned earlier I also buy only the 5 packs and many times there is one duff one. They give you one free if you buy 5, I don't think anyone can say why but I can say it has happened to me too more than once.

Hi Q as far as the coil is concerned I agree with the others , it's probably a duff.

Now as far as recoiling dual heads decoy gave me an answer in THIS thread , just look at reply No.6.

Last night I did three single coil heads with a 2mm instead of a 1.5mm , BUT I have also found a tip that needs to be shared when doing this.

When you have wrapped the coil and ready to put it in the coil head, take out the 2mm rod/drill bit and put in a 1.5 mm rod/drill bit as this makes the coil sit in the correct place.I have yet to do a dual coil as I don't have any dual head tanks.Using the larger inner diameter coils it makes it a lot easier to wick and the taste is exactly the same.I can only see it being even easier with the 3mm inner diameter.
