Protank rebuild ohm question

[Hey.al]

Hi so I'm new to rebuilding coils and have been rebuilding protank coils for about 3 days. I am using an itaste v3. Some things I am noticing. 32 g kanthal has been working way better than 28 g. But, I was under the impression that a lower resistance coil like 1.5 would produce more vapor than a higher ohm. I am noticing the opposite. My 4 wraps around a 5/64 bit came out to 1.5 and it was not putting out as much vapor as my 6-7 wraps reading 2.7 resistance. I just did a 5 wrap and it came out to 2.0 resistance and it is producing really nice vapor. So, what's all the hype about low ohms when I am experiencing more vapor with higher ohms? The itaste v3.0 maxes out at 11 watts.

makes no sense to me...... i'm on a protank II mini........
I vape 32 ga at a minimum of 1.8 but as high as 2.5...... higher ohms you get more flavor, but takes longer to heat up..
I love how the 1.8 heats up, but flavor is less.......

if you're gonna go with a lower ohm, use the 30 ga....... it has more surface, which I suppose is related to taste......

my overall favorite build is 30 ga, a 7/6 wrap, at about 1.75 ohms....... heats up fast, and has lots of surface.....
plus its a lot easier to rewick 30 ga than it is 32ga.......

mac has to be around here somewhere.... he knows, he can guide you best.......

do a search on protank microcoil discussion and find a post for mactechvpr .....he knows this stuff

[Hey.al]

thank you, good advice. Maybe I need to wrap on something smaller than a 5/64 bit. Like a syringe needle or something?

Also, what are safe ohms to stay within when using an itaste v3.0? I do not have an ohms reader because the itaste will do that for me by pressing 2 buttons together. I've been staying between 1.0 and 3.0 resistance but I have rolled coils that were higher and lower than this and just didn't use them because I don't want to take any risks and I don't know the safe range.

Stick with higher ohms. 2 to 3 ohms. Also, the higher the resistance, the more surface area there is for the coil generally speaking. The more surface area, the better the flavor. Sticking with higher ohms is not only safer, it'll give you the most options for varying voltage settings.

This ^^^ I'm guessing you're butting up against the limits of your device with your builds. My SVD complains at about that same point while my mech fires away just fine. Maybe it's time for a mech mod?

I've built them several different ways, and my experience has been that for something like the VV or MVP, using a thinner gauge wire for a slightly higher resistance yields better results.

I have rebuilt my wife's protank heads using 28ga wire in resistances from 1.25Ω to 1.5Ω. They work nicely. However, the ones I've built using similar wraps using 30ga wire for around 2.0Ω actually perform a bit better.

The 30ga wire heats up much faster then the 28ga. I also think that there is something to the suggestion that you will get a fuller range of adjustment without hitting the current limit on a device like the VV or MVP using a higher resistance coil.

 

[Hey.al]

Ok, I'll keep experimenting. So is a safe range for my device somewhere between 1.5 and 3? I do worry a little about battery exploding in my face. I am new to this rebuilding and when i do a search, i can't seem to find a good topic about rebuilding coils safely.

I build my Protank 2 with 28g, 12 wraps on 20 guage wire at about 1.1 ohms. I somethimes build it around 2/32 drill bit for little higher ohms. Someone was right, higher ohms will give you more range for VV devices, but if you use VW and you find good walts, it doesn't matter what coil you put in it will all be done for you for volts part. However, more surface area, more juice evaporizes, meaning more flavor. And lower the ohms more clouds "should" be there, especially density of them as well. I usually build 0.5-0.9 on Hana Modz V3 and 1.1-1.6 ohms for my ProVari and/or Semovar.

In overall it all depens on built, rda, tank, etc and then power of your device and your taste buds. No two people are alike especially when it comes to flavor.

I've grown.... my new favorite wrap is now an 8/7 wrap with 30 gauge...1.95 ohms........

even more flavor than the 7/6 wrap on 30 ga..... 1.75 ohms.......

I wrap on a rivet.......... larger than a 1/16" bit, but smaller than a 5/64" bit........

and I still put 2mm silica through the coil, and 2x 1mm on top for flavor.......

no problems of any kind..........

PT's design kind of limits what works well with them as far as coils go, and it's fairly limited. A look at how tiny the vapor chamber is, and how much it is able to wick makes that pretty evident. I have found 1.5-2.0 ohm works best. I have settled on a 9 wrap coil on a 16ga needle, 30ga micro coil wicked with cotton. It comes out to 1.8 ohm. I vape them between 3.5 and 4 volts, depending on juice.

ProTanks are a solid everyday performer, not a cloud machine. If you want to push the envelope, buy a dripper or an RTA. There are many to choose from. Good luck.

I've tried just about every build one could think of in a PT head. I've used 28, 30 and 32 ga. kanthal. I've tried different size drill bits, and several different kinds of wicking material. The best so far is to use 32 ga. 6 evenly spaced tight wraps (1.8Ω)on the second smallest spindle (1/16th) on the Artistic Wire Coiling Gizmo with 2 strands of 1mm hemp yarn for wick. Always use a 1/16 drill bit to seat the coil in the head so it doesn't slip and is in the best position for wicking. I DIY almost all of my own juice at 50/50. This setup will knock your socks off for flavor and vapor at 7 watts. I think wicking is key to get the best flavor and vapor. I started by using boiled cotton and my wicking was inconsistant. I moved up to 2 strands of the 4 strand Peaches and Cream Cotton yarn and that was much better. Then I got some 1mm hemp and tho it's kind of unruly, delivers the best flavor and vapor. I do rebuilds for a few friends and everyone noticed the improvement when I switched to the hemp wick. I'm still on the hunt for the perfect vape in a PT head, but this is by far the best I've hit on so far.

If you like 1.5ohm and the V3 works there then build there. The V3 will protect itself if you build to low and refuse to fire.
If you want more Vapor and want to keep the 1.50 builds just change the Protank bases out with Areotank Bases.
Instant improvement.
Your issue is not the air channel of the heads but the limitations once screwed onto a device. some devices completely block air flow making the protank a fail(Provari) but it is not the tanks fault. It is simple design incompatibility.
Aerotank Air Control Base eliminates this issue and allows for much better air flow control. You can increase Vapor or decrease and increase flavor.

Ohms Law is Ohms Law and you cannot get away from it. Your varying experiences are probably due to the particular PV you are using and even the particular brand of batteries. I've used the same carto/clearomizer/etc on different devices and batteries and have noticed small variances with each one. Experimentation is unfortunately inevitable to find the best vaping experience for you but found the following website here on ECF and it is a huge help. Check it out. I'm not connected with this website just trying to be helpful.

I use 28 g kanthal, 11 wrap microcoil (it's a tight fit, but it works) wrapped around a paper clip. Hits at 1.1-1.3 ohms everytime, wicked with cotton the tast is amazing, and it kicks out a decent amount of vapor. I run it at 6-6.5 watts on my mvp
