Titanium coil builds

[BreeZyCloudZ]

This was my first titanium build, im still very new to it, i read online about it, cleaned it with iso alcohol, wrap a compact 12 wrap dual, came to .25, exactly what i was going for, 24G Ti around 2.5mm, on a Sigelei 150w TC, pulsed at 10 watts very lightly to fire evenly, i think i settled at 45 joules at 375 F, i mean the flavor hype is no joke, i definately tasted all juice and nothing else, you know how you smell a juice and you think itll taste that way, then it doesnt, well with Ti, juice taste how it should, anyways heres the Ti build

Thanks breezy. Has your mod read dry wick no liquid? Are you sure you are in TC mode?

Yea?

I'm using an evtc mod and 24ga TI wires. On dual coil, I am getting 0.08ohms. I am vaping fine but I'm not used to such low resistance. Is there any downside to this? A friend told me battery life is affected but when I remember my electronics class, it should not. As watts (and temp) is regulated, lower resistance would just mean I would hit that temp a lot faster than on a higher resistance coil (0.5ohms).

26g Pure Ti Unkamen wire, 2mmID, duals, slightly spread, .2ohms. Mounted on my new Aromamizer. Killer vape, intense flavor using Churios ejuice. The wire is springy so alot of fiddling to get it right.

No, there is no downside, your coil will heat alot quicker but you can just adjust joules if you dont like it heating as fast, it might actually save battery life as you dont have to hold the button down forever to actually get some vapor

Aromamizer I like it!!

I have to say my favorite part of Ti and TC is how much juice im saving!! But i was wondering, is it possible to make for complex builds? maybe a clapton/fused clapton/alien? Could i just make the core Titanium and clapton the outside with Ni80? I mean the flavor is already great with Ti, but if i could throw a fused clapton or alien in there, itd be killer

What is an aromamizer?

What is an aromamizer?

It's a semi new tank. It has separate coil and juice chambers so your juice is not cooked out as it sits around the chamber like in a Kay fun or an Aspire tank or most of them.

Pretty cool design.

You can, but then we see the disadvantage of temperature control based on measuring delta-resistance.

Remember that resistance of parallel circuits is the sum of their reciprocals. Since the outer wraps of the clapton have between x20 and x100 the resistance of the inner core, it's contribution to the overall resistance is negligible. For example, if the core of a 26ga/3" clapton is 0.25ohm, it would need a wrap of 32ga/30" long at around 12ohm. The overall resistance is 0.24ohm of which the outer wrap contributes only ~4%. However in terms of mass that needs to be heated, it is around 75% of the material.

TL;DR doing temperature controlled claptons, the temperature "measured" (calculated) by the mod is the inner core temp and the outer wraps will be relatively a little bit cooler.

The solution is just to put up the temperature a bit, e.g. set it to maybe 260C where you would normally be happy at 230C.

Ok so been doing a bit of reading up on hybrid claptons and I would appreciate some input on this build.

It's 24g gr1 ti core with 32g kanthal claptoned around it 8 wraps, 2.5mm I.d and it's coming in at .13 ohms when running dual. This is bang on with steam engines prediction and my vtc mini is reading the same. If anyone here can confirm that I'm correct in thinking that this should work in tc mode and the current should flow through the path of least resistance I.e the titanium core? Any thoughts on how this build will affect the temperature settings?

Similar as the example I described in my post above yours: the clapton wrap is of such high resistance that it will hardly affect the temperature reading of the titanium core wires. However, 75% of the material is in the wraps. The core will heat up first and the wraps will be relatively cooler. I can't give you a formula for how much higher you have to set your device, but for example, I use 265C on my dripper with Ti claptons where 240C is enough on my Goblin Mini with regular Ti coils.

Thanks for coming back to me wisk. Gonna wick it up and have a play & see Wat happens but just wanted to know I wasn't barking up the wrong tree So your running Ti claptons too, are they similar to mine or are you using different wire for the wraps? Are you pleased with the results? My concern was that the kanthal would take to long to heat up and not actually make much difference

Set your resistance. Set your power and wire settings. Wick it up. Drop a small amount of juice on each coil. Hit the fire button. If your wick incinerates, you are not in TC mode[emoji51]

Mine is Ti wrapped, but I think it has around the same thermal conductivity as Kanthal: 19 W/mK. Yes it heats and cools slowly, that's why you need to raise the TC settings a bit.

I might try fused claptons next instead of staged.

His photo shows Ti mode, the VTC Mini doesn't auto select like the DNA chips.

It's an idea to do the cotton test, but dry without eliquid. When the cotton starts to yellow, that should be 220C on a regular coil. You can use it to calibrate your final setting.

Cheers for the reply fellas, whilst the vtc is a great little budget tc mod it does have its limitations. It's underpowered in ti mode but now it's running 75w its not so bad. Unlike the dna 200 which I'm waiting on as we speak I'm unable to alter resistance or the tcr on the device. WiSK I've tried the cotton burn with ti coils before and as I've discovered another issue with this device is it has no dry coil sense and cut off. Even at 100°c it will continue to fire a dry wick at 4 watts which will cause singed cotton. Not sure if this is a common feature with the vtc mini as I was unlucky and had a defective unit that suffered the sleep/anemic vape syndrome until the firmware/voodoo cured it!

Well the claptons are working at the moment pretty good. Got the watts right up as ramp up time seems a little slow but I had that using twisted ti coils also. Have had to crank the temp up to about 290°c in order to get the vapor and warmth I like, little concerned as unable to see the ti core to monitor any Ti02 production but then it's still well under the temperature oxidising should occur providing it's reading correctly due to Kanthal wraps and any insulating caused by them. Think these coils would preform better if I had a bigger initial boost of watts from more powerful mod. Need some different ti wire gauges so I can make some pure ti claptons, WiSK which gauges are you using? Gotta order some stainless wire as joytech have just bestowed the vtc with ss mode so may as well order a boat load of wire.

Sure there won't be any TiO2 at these low temperatures, especially submerged in juice . Just don't fire it unregulated in open air.

My coils are 26/32 with a 26 running parallel.

I downloaded the new firmware, screen seems a bit busy now.

Yeah I guessed it should be fine.

That sounds like a lot of wire, Wat sort resistance you getting with those mate?

I've upgraded but only to version 1.30 which comes in the same download. It has ss mode but keeps screen the same as I don't like the scene layout of version 2.00. Why have a nice big screen that's clear and easy to read then stuff all that info on it. I don't care how many puffs I've had.

 

[WiSK]

It's 0.06ohm
