RBA - Help Needed for Adjusting Ohms

[Kh888]

Hi,

I have been experimenting with RBAs; IGOs, Trident and Omega. I use 30 gauge Kanthal and usually cotton, but sometimes will use silica.

I have noticed is that the vape is often too hot for me. Most of my coils are at 1.7 to 2.0 Ohms and I use a Provari Mini often at 4.0 volts.

How can I best adjust to cool off the vape, but still keep the taste and receive a good amount of vape? Do I increase the number of wraps on my coil to increase the Ohms? Will that help, or are there better suggestions?

Thanks in advance for any help you can pass along!

have you tried simply lowering your volts on the provari? It goes down to 3.3v if I remember correctly. That's the first thing I would try rather than rebuilding.

To lower the watts of your build you can increase your resistance by adding additional wraps to your coil or increasing the diameter of your coil or a little of both.

Thank you. I have tried lowering, but it seems I get a bit less vape. Then again, it might be my imagination. Could I also move to 28g Kanthal?

I confess...Ohms and resistance, etc just confuses me. Add in wraps, and wire gauge and my head spins!

The lower the gauge the lower the resistance. 28g will lower your resistance and not raise it. You would need to go to 32g which is a bear to work with as it's so thin. You can try adding a wrap or two more the next time you build a coil with 30 gauge. Have you tried switching drip tips to see if that makes a difference? Sometimes this is all it takes.

Try lowering the coil some, maybe even with the air hole or just below it.

Also instead of 4 volts try 3.8!

More air (bigger hole) and a longer insulated drip tip with a wider opening should cool things off for you. The key here is air. More of it flowing over the hot coils and a longer distance for it to travel before it hits your face. Drippers are always hot and the juice will always and only vaporize at a certain temperature, so changing your wire gauge, resistance or coil size/position will only get you so far -- and only in as much as whatever adjustment you make allows more air into the mix. For example, a larger (ID) coil or a nested coil both supply more available wire surface area to be cooled by passing air.

Thanks for the great input - much appreciated!

Make sure your air holes are directly in front of the coils.

I think I am now getting the setup improved; air holes aligned and coils with more wraps. I may still find RBAs too much for me - I am kind of wimpy ;-)

I think getting thicker wire will make a lower resistance but cool the vapor off a little... 28 gauge takes longer to heat up and provides a smoother vape in my opinion... 32 gauge at 1 ohm @ 4.2v would be harsh where 28 gauge at 1 ohm @ 4.2v is a lovely vape. There both a little over 16 watts... more air too
