Burnt out coil after a day!

[gdacosta]

I've just watched a video on youtube. Most of it seems simple enough. There was just one step where I couldn't see what he was doing. After the cotton is in and the sides are trimmed he does something with the needle inside the coil. I couldnt work out if he was just pulling it in a bit or twisting it.
He would be just fluffing the cotton, spreading it out a bit to cover the juice holes without leaving big clumps of cotton. You'll find the coils are better with looser cotton. Remember that coils will eventually burn out, but you will get to change cotton at least once. Good luck.

I'll watch it again when I've got some more supplies. Will probably buy a box of coils and some cotton then I've got a few back ups and if I swap the cotton each time i first change the whole coil it won't be as frustrating if I mess one up as I'll have another I already sorted.

Oh, and forgot to say that the isub coils struggle with thick juice. 50/50 pg/vg is ideal, but anything higher in vg terms needs longer between pulls or expect burnt cotton. It's the small juice holes...They can't let thick juice in fast enough if you take regular puffs. Still good coils, but as you buy other tanks in the future you'll see what I mean.

Most of my recent juices is either 70/30 or 80/20. No problems yet that I've noticed but then I have nothing to compare it to.
I also have one thats 100% VG but I never use that as my first juice with a new coil. Not sure if it makes a difference but I'm a little worried about that one going in first.

Going to go to a real shop one day who know what they are doing. The shop I bought my cool fire from probably just wanted my money it's a newsagent with a second counter for ecig stuff. The other shop is just ecigs but I got the impression the staff member wasn't very knowledgeable.

Out of the 15 Cubis SS316 coils I've bought, 12 have been dodgy. So yes, its easy to get some dodgy ones...

Did your cubis flood when using those dodgy coils?
My cubis is always flooding and its doing my head in!!
Using the 1ohm that came in the box.

No, never suffered flooded coils, just the damn things burning out quickly (a couple only lasted 3-4 puffs). When I contacted Joyetech UK they said the SS316 coils should NEVER be used in VW mode and that the instructions are wrong. After getting that response I contacted the Joyetech main site and they said they're fine in VW mode and also sent me settings to use it in VT mode, which produced no vapour at all!....haha.

lol *face palm*
Are you using a vtc mini as they released a special firmware update just got the cubis.

No, I'm using a Cuboid with the latest firmware update.

I would say that the part you can not correctly see, where he is inside the coil, is him positioning the cotton into place over the juice flow holes.

To start with, try using a similar amount of cotton that came out-someone else mentioned dry burning, when your cotton is out, give them a quick fire up till they glow a few times (at a lower wattage than normal-personal preference, I find it is a lot harder to break coils this way), and it will pretty much clean your coil-then you are ready to put some cotton in (I suggest Japanese cotton, Muji or Cotton puff, Cotton puff is the cheapest at under £3 for 200 sheets-and you can make a fair few coils out of each sheet, so I would say enough for 500-1000 coils depending on what you are building.

You want to look at the coil as it is, and get it looking the same really. The cotton does not want to be too dense, but not too loose.

Once you have the juice flow holes covered inside, give it a few drops of juice-and bob's your uncle. If it turns out it went wrong, and Bob's your aunt, simply try again, you will get there, it will only take a few attempts max I would say, I would not be surprised if you get it first time though.

Good luck, you will save a lot of money , and it is not too hard I promise.

In relation to the cotton used. Does it really matter where you buy it from.
Just thought I'd look on Amazon. There's a company on there called FreshiUK, selling 10 pads of Japanese cotton for £2.10. April is going to be the month I give this a go. I have 3 burnt out coils to practice on and my last one in my tank now.

Look at muji.eu and the unbleached cotton pads. About the same price as Amazon for over 100 pads.
