Fortunately it’s fairly simple! Pure titanium has a temperature coefficient of resistance (TCoR) of 0.0035 - Just like resistance, TCoR halves when put in parallel, so a dual coil will have a TCoR of 0.0017(5). If you can’t set TCoR, then the temperature reading will not be meaningful, but you will just have to set it a bit lower (just like when we use Ti-wire on Nickel-only TC-mods)…

I’m vaping this dual Ti coil at 500 degrees comfortably. Some single Ti coils I have to vape around 400 degrees. I really don’t know what this means though… just a comparison. Then again it may be the juice.
Are there any links where I can read up on this?

Damn it …I was just gearing up to get myself a crown tank and now @ Pro_Vapes is saying this one is the best !! I’m glad I waited I guess .

You won’t be disappointed. This set up is the best of everything.

I’m sure I’ll be pulling the trigger soon. I’ve been recoiling all my tanks with titanium and it’s been quite impressive the amount of life put back into these oldies …my Cthulhu which I wasn’t impressed with is actually quite good now .

That was why I started this tread a little while ago.

What I have found is there is no advantage to setting the TCoR unless you know exactly what you are doing. I’m getting the same if not better performance from my current TC mods. If you don’t set it just right there will be problems when using Ti. For me I think the Cube X 2 is a little too technical and wont appeal to people that just want to install a Ti setup, set resistance and vape. I was in dry hit city until I figured it out after 8 hrs. There need to be detailed instructions for how to set up this mod.
I tried this set up on dual Ti coils and experienced a ton of dry hits. When I set it back to .0035 the vape smoothed out. Where can I read up on this and does this apply to all gauges. Seems like it would vary with your wire gauge.

Sorry, I just went google berserk, but unfortunately I didn’t save any of the links - I know one of the starting points was this post: temperature coefficient of resistance - EE Web
From there I went a lot of places…
EDIT: The reason for my research was dual Ti and also because some of the Ti-wire I had was not grade 1, but rather an alloy (so the TCoR wasn’t the same)…

Sorry for the embarrassingly stupid questions but as you know I have never done this and know ZERO when it comes to builds…
But I have some 24g stainless that @quitter1 was so graciously generous to send me and I have no idea how many wraps to do for the dual rba on the TF4V? I’m sure there is a topic about this but I can’t seem to find it? 5 is the number I seem to find but I would like to stay at .25 or lower? I really don’t know and I’m sorry for the dumb ass question but I am quite seriously unedumacated and have no idea where to start…

Most will say calculate your build on Steam Engine. I haven’t built SS in a while… maybe someone will chime in. @Damondo

I actually have steam booked marked come to think of it but never had a reason to use it. I’ll go over and check it out and play around and see if I can figure out the basics at least, thanks!
I’ve been using the 26g lately. I wouldnt do 24g duals, it’d be too low and a hot vape. 7 wraps of 24g SS on 3mm bit, dualed, ohm’d out to 0.15 or some crazy shit like that. I’d only single coil those puppies if I were joo.

Thanks D!
It’s all I have to work with since I haven’t gone shopping yet and quitter was kind to send me some-
So you are saying I should get the single RBA NOT the dual then if I’m using the 24g? NM obviously that’s exactly what you are saying lol
Also on steam I see a lot of different SS types like 304,316, 316L elite, etc…what is that all about? is that something I should hit quitter up on?
That’ll be a tight fit in a tank.
I believe @quitter1 gave us 316L. I have no experience with that tank or deck, just dont dual that 24g. Save that 24g for your single coil applications.

Gotcha…last stupid question (maybe) what’s a good target resistance then? I must be doing something wrong and I will have to REALLY do some more homework before I even attempt to wrap because this is literally uncharted territory…plus I have to research the whole 3mm bit thing- The only tools I have in my vape gear is the tiny screw driver I got with my dripper a while back and I made one coil with it way back in the day when I tried dripping and abandoned it and building on a tank couldn’t be farther from that…
Like leg length and all that I have no clue about
I’m looking at all the info on steam and it may as well be written in zwahili

Got any precision screwdrivers or drill bits laying about?
1 Like
yes and no lol
I will have to go look around in my tool shed but they are all pretty loose and not labeled, but I gotcha I can figure that out. Just wanted to make sure a 3ml bit is what I should be using
1/8 for drill bit. Thats the one you want.

k, is that standard across the board? or does that depend on the wire? like 24 vs 26, Ti vs SS, etc?
Thanks a lot for helping me too guys- I really want to get some of this down before I get all my equip and then really flood ELR with my screams for HELP!
