Billow v2

[Yojunhao]

Hi everyone.
Not really expert. Here's a question. I recently switched to rta and got the billow v2. Build 30g 2.5mm 11 wraps nickel, my ipvd2 reads 0.1 . As i fire longer than 3 seconds, i can feel my vape is getting weaker. Why is this so?

how much watts are you running at? not sure if 11 wraps gives 0.1, you getting any shorts?

 

[Yojunhao]

30 Joules.

I have upload a pic of my setup. Does anybody know what is the issue ?

My guess would be wicking. As you fire you're drying out the wick and for some reason the way you have it wicked isn't wicking juice fast enough to keep up. Can't think of anything else off hand. How tight is your cotton in the coil? Drippers seem to do better with tight wicks but tanks seem to do better with a wick that's just a tiny bit snug, not tight at all.

Hi! Is anyone help, how to biuld Billow for TC? what best combinations?

 

[Hans Wermhat]

The wicking on that tank is tricky. It took me a couple of tries to learn how to do it. Can you post a pic from the side? I think it's the tais on your wicks that are causing the problem.

The tails are placed nicely on the channels. Yes. My wick is extremely tight..i had to twist a lot to fit it in the 2.5mm hole

I do not know what is best. However my step up for nickel is 30g 2.5mm i do 10 wraps now. I get 0.09 on my ipvd2

Thanks! 10 wraps for 2 coils each, right?

That is way too tight. It should slide in with some resistance but not a whole lot.

 

[Yojunhao]

Yeah and it reads 0.09. So what temperate should i set for temp control?

450 F is typical but you'll have to adjust it to what you like.

1 more question. Right now. 10 wraps 0.09 reading. But why is it 1 side of my coil is gunked. What is wrong?

Are the coils heating evenly? You might have uneven heating where one coil heats up faster than the other and gets gunked. One of the wraps on one of the coils might be shorted to its neighbor.

I've seen guys use uneven coils intentionally to get more vapor from one coil and more steamy / flavorful vape from the other. How was it vaping?

 

[Yojunhao]

I did not get a short reading
And visually all looks fine

It's not so much a short reading but that one of the coils is slightly different in resistance from the other. Do the coils heat evenly?

 

[Yojunhao]

I'm using nickel. Is it possible to see if its heating equally? I try to make the dual coil resistance the same by getting the first resistance. Then putting in my 2nd coil and get the figure which should match the first resistance /2

That would do it.

I'm not going to say dry heat the coils until they glow a dull red to check for even heating because the NiO police will flame me.

 

[Yojunhao]

That is what I did. But i still experienced this 1 side gunk coil
