How to gauge the ohm when coiling?

[nixoahz]

Hi guys..

Can I know how do you guys gauge the ohms when rebuilding the coil.
Does the ohms depend on the resistance of the wire or depending on the number of time you coil?
And also while sourcing for wires i saw wire with afew number of gauge like example 22gauge, 24gauge blah blah.. Which one good ah?

Sorry for asking.. Noob here ah. hahaha.. I saw some treads to learn but like abit chim. need to coil how many mm gap or something like that I see already also confuse.. Watch youtube they just take the wire coil on the wicks nia.

dont guage the resistance. you have to measure the resistance. generally, the more coils you have the higher the resistance. it also depen on the gauge of the wire. the bigger number have a smaller dia(thinner) and higher resistance value.

By experience. You need to build your first coil first to understand what the others are saying. Example, 6 wraps of 32G wire on a 1.8G needle will give roughly 1.8 to 2.0 ohms. More wire means more resistance, less wire means less resistance. So 5 wraps may give you roughly 1.4 to 1.6 ohms now. 7 wraps may give you 2.2 to 2.4 ohms. The lower the wire gauge, the lower the resistance. So 6 wraps of 30G wire on a 1.8G needle will now give u 1.4 to 1.6 ohms. Less resistance means more power. More resistance means less power. More power = stronger/hotter/denser vape. Less power = lighter/cooler vape.

Ultimately, you will still need to use an ohm meter to measure the exact resistance.

Welcome to ECF. We all started out and there was a lot that we just didn't understand. I'm still learning after a year and will be another year from now.

Here is a good starting point for information.

Hey guys.. thanks for sharing.. ya i had coiled one ytd after i got mine. But having trouble to gauge the resistance so hence im asking how to gauge now. After reading what you all shared i understand already. So the higher the gauge of the wire the thinner the wire is and thats better?

It depends on your preference. But ultimately, get an ohm meter to understand better the coil that you're building.

"Gauge"

No. Measure with a multimeter or ohm meter.

Obviously you will have trouble estimating/gauging the resistance because this is like your 2nd or 3rd coil? Try to repeat it 10 times, do you think you can gauge the resistance now? People are able to do so because they have done it numerous times with different wire sizes. Estimating the resistance is 1 thing, you will not able to tell off hand if you have a short on your build without an ohm meter. There is no shortcut in this department, please read up more and watch more videos.

Never estimate or gauge...get a ohm meter. It's not expensive and it can be found in any decent hardware store...even those 2 dollar shops have it.

Even experienced vapers use ohm meters, don't be smart and think it's ok to gauge and blow it.

I think there is countless of post mentioning about coiling and resistance checking, more reading will actually tells you how to coil and check and even what ohm meter to use. No point gauging ohm while coiling. Shocks may happen in any where within the tank or the coils touching, just be safe than sorry.

I get what the OP is asking about.

To build a typical micro/ nano coil, I use about 4" of kanthal around a 1.4mm screwdriver. Gives me about 0.8ohms for dual coils at 10 wraps consistently. Every less wrap will drop resistance by 0.1ohms.

You'll need to keep coiling, at times hours on end. I ever start on a new build at 11pm and ended at 2.30am. I usually make new builds and coils on a fortnightly basis, so much so that my builds have been accurate down to 0.01ohms difference. You need to keep doing it, keep practicing and keep experimenting to get what you want.

And here's a word of advice; don't stinge on kanthal and don't try to reuse a coil if you decide to change the diameter. And don't only experiment with your coils, play with your wicking methods. I tried a new wicking method that holds the same amount of juice as a micro coil cotton bed but double the vapor.

Vape on brother, you're just getting started.

Basically we are using resistance wire. So it doesn't require coils the thinner the wire the less current can pass through hence more resistance. Wrapping the wire against the wick makes you run the wire some distance thus increasing resistance.

That said, if you are using mechs better test with a multimeter or ohm meter.

*edit:
When using cheap multi testers, set to around 200 or 20 ohms if available, then toouch the 2 probes together you will usually get around 0.4 to 0.8 internal resistance. Take note of the reading. Then touch the probe to both ends of the coil if you get a reading of 2 and internal resistance of .6 then you have a 1.4ohm coil.

Haha. Ya thanks guys.
Btw how often you guys rebuild it?

I rebuild mine whenever I am free and when I want to try something new. When I'm feeling lazy, a well built parallel coil can last me about 3 weeks before I decide to change it.

Best to get a multimeter just to check(safety first mate)

Also, like desmond, I rebuild as and when I feel like it. Been running the same coil for about a month now just swapping the cotton out

 

[Steamix]

Either a good multimeter.

I got me one of these :

After you've done a couple of builds, you get an idea how many turns you'll need.

Still measuring the atty after assembly to check for shorts and the exact ohmage.

I'm a paranoid dude so i use both the multi meter and the ohm meter just to be sure

Google for "pv web apps".
This is what I've been using. The first link should be what you want. It has an online calculator to estimate the resistance of your coil.

Hey.. Guys really thank a lot for the info shared.

Happy vaping guys..

 

[Firevampire]

Hope you are vaping safely and getting your ohm reader asap.
I also had the same problem as you and now I can vape safely with my reader which is so hrlpful and so.

Just remember never think u know the ohm just like that. = )
