Temp Control....reasons for it?

[crammit442]

I guess I've been in a cave somewhere for five or six years. I've used a/kayfun Lite (24 ga kanthal @.4 oh) on a Super T mech mod w/ success for years. I stopped at the local shop for a/few 18650's the other days and was rocketed forcefully into the edges of the 21st century. I ended up w/an eVic VTC dual and a REALLY open atty. It worked as designed, but I'm DEFINITELY NOT a DTL cloud chaser. MTL only for me. I'm sure when I come to understand all this new gadgetry and nomenclature, I'll be the better for it. Right now, I almost feel like I've discovered a solution looking for a problem. W/o question, the ability to control wattage is already a benefit in tailoring heat and taste. I'm assuming as I play with the various wire material and gauges, the reasons for temp control will become apparent. I went on a bit of a spending spree at fasttech and have wire in Ni200, SS316, Ti in varying gauges on the way. If anyone can give me a relatively simple explanation about when, why, and how temp control is used to great advantage, I'd be appreciative. The is in advance.

P.S. please take it easy on me.....

For TC you would need to use another metal for coils. Kanthal doesn't work. SS, TI or NI.

TC does add a level of control when working correctly. Smooth consistent quality of the vape produced. No dry hits or burnt wicking. Even when the ejuice runs low, no problem other than loss of vapor production.

TC is just a way to limit How Hot a Coil can get.

When the e-Liquid in your Wick runs dry, or when the Wick can't keep up with the power that is being supplied to the Coil, there Isn't enough e-Liquid to be Vaporized. Without e-Liquid in your Wick to Exchange Heat from the Coil, the Coil gets Hotter and Hotter. And you get a Gawd Awful "Dry Hit".

TC can prevent this. By Setting a Temperature Limit so even if your Wick Runs Dry, the Coil Temperature will not go over the Limit you set.

It does this by Knowing how much the Resistance Change should increase when a certain Wire Alloy gets hot. The Mod Reads the Resistance of the Coil at Room Temperature, then it does some Math and records what the Resistance should be when the Temperature Limit is Reach. It then Reads the Resistance during t5he Entire time the Power Button is pressed. And if the Resistance reaches the Calculated Increased Resistance, the Mod know that the Coil should be at the Temperature that the user has set as Limit. So the Mod backs off the power an Very Rapidly turn the power Off/On to maintain the Calculated Resistance of the Temperature Limit.

But for all this to Work, you have to use a Wire Alloy that has a Significant Resistance Change when the Alloy goes from Room Temp to about 550F.

Ni-200 (Nickel), Ti (Titanium) and SS (Stainless Steel) can all work in TC Mode. Kanthal can Not. Because Kanthal's Resistance just doesn't change much from Room Temp to 550F or so.

Ni-200 (to me) is a PITA to make coils out of. Because the Coils are Kinda Flimsy. And if you try to use a Thinker Piece of Ni-200 Wire, you get Crazy Low Ohm builds. Ni-200 should also Only be used in TC Mode. So you can't switch a RTA/RDA to a Non-TC Mod.

Ti is easier to work with. But I had kinda Funky Results with it. So I can't really say much about Ti.

SS is the Best of All Worlds (IMO). Easy to Build with. Very Fast Ramp-Up/Down. Very Clean Taste. Works Well in TC Mode. But can Also be used in regular Power (VW) Mode.

Last thing... Some Mods do TC better than others. And on some Mods, it can takes some Experimentations to find what Settings and Coil Ohms work best for the Mod you are using.

TL/DR:

TC can prevent Dry Hits. Or help a person use the Maximum Wattage before getting a Dry Hit.
Ni-200 should Only be used in TC. Not in Power/VW Mode.
SS is IMO the Best Wire to use with TC. SS can also be used in Power/VW Mode.
Some Mods do TC Better than Others.
TC can take some Trial and Error to get it Dialed In.

Excellent explanation! So just like mech mods; lots of playing around to get exactly what you're looking for. Thanks for the help.

Yeah... Getting TC just the way you want it can sometimes take some time.

But when TC is working as it should, it is Very Cool.
When it's Not, its Kinda Evil.

LOL

In the beginning / just starting with TC can seem like lots of fiddling & futzing around.

There is a learning curve, like all different methods of vaping have.
Some folks love it, some don't see any point or get any benefit.

BTW - Since SS can be used in Both TC and in Power (VW) Mode, it can help to get your SS build worked up and Working Perfectly in Power Mode 1st.

And then Switch over to TC Mode and see how Changing the TC settings effect it.

The ole learning curve.....seems there's no way around it. No matter what you read or see, usually gotta get your hands dirty to REALLY "get it". I really appreciate the help.

Another advantage to TC, in addition to the above, that is rarely mentioned... I don't always have tanks/RTA's dedicated to certain flavors available & switch flavors often. I just vape the wick dry & add the new flavor. Works great for me...

 

[CagedSpam]

I was slow to try the TC "thing". Using an eGo CLR Ti coil at under 400 degrees, was feeling pretty good. A day or two later it starts getting dry and off tasting - I'm thinking - Ha! this TC thing is bogus, we've got a problem here, all smug.

Anyway, it was because I had vaped it dry and it TC kicked in, Filled the tank again, no burnt taste no coil scorching. So TC is pretty cool/hot in my book

That had never dawned on me. Maybe I will put one the Nanos in tc. Thank you.

Hope it works for you as well as it does me...

Hope I can get it to work at all!

Man, I dunno if I could do that?



I've spent about 8 Years taking Every Precaution Possible to NOT run a RTA Dry. Doing it Intentionally seems to go Against Every Primal Vaping Instinct I Have.

Power Mode = BAD - Temp Control = No worries

I don't use TC with mtl RTA's. I find I can't get enough TC wire into the atty to get into the 1 to 2 ohm range I like for mtl. I also find that a kanthal build with a plus ohm build mimics TC pretty well. They ramp up pretty quick and hold a pretty stable temperature. Lower resistance builds in dl RTA's are quite a different story. If I hit them with enough power to ramp quick they will quickly heat up to temperatures that are hotter than I want to vape, limiting my draw time. In this case, TC is appreciated. Quick ramp up and the temperature of the draw stabilizes throughout the draw regardless of how long the draw is. With all that said, there's the mod to be considered. Seems most every mod claims TC. Some of those mods just don't do TC IMHO, others provide protection against dry hits but do not stabilize the vape, there are still others where I have no idea what they are doing. It seems that the vape community has acclaimed DNA and Yihi the best TC from what I've experienced. Even that is conditional. Evolve sells DNA electronics to many manufacturers. Some of those manufacturers do either a poor job or no job at all regarding to setting the parameters of the firmware to work correctly with the mod. Getting all of that calibrated can be a bit of a trick. Every Yihi equipped mod I have purchased to date has been calibrated. There are other mods that will do TC well. I can't make a list as I don't own every mod made. The Vaporesso Revenger does great TC right out of the box. So does the tiny little Eleaf kiya. Think Vape's EXUS will do TC but only using a manually entered TCR value. I'm using a value of .00165 as opposed to the standard .00092 value for SS. TC really isn't "prime time" or "plug and play" across the industry by any means.

No risk for dry hits, lessens the risk of inhaling dangerous byproducts (which will be produced before you taste something off), consistent vape from hit to hit without excessive heating up if chain vaping, wicks and coils last far longer. Those are some of the main reasons I use temp control exclusively.

I like TC for;
Dry hit protection. I forget the JFC.
Consistent vape even when I chain vape.
Somewhat better battery life. 70W to 25W is less load than straight 70W for the same amount of vaping time.
