Temp control guide for beginners

What’s This Temperature Control All About? Lets Take A Closer Look

The e-cigarette and vape market sees new product hitting the shelves on a daily basis. For quite some time now, temperature control features have been considered a standard, must have feature on box mods and any vaping device that’s compatible with an RDA. The question is…why?

The long and short of it is, vaping brands are trying to make your vaping experience better…they want your clouds to be BIGGER, your flavour BETTER and your vapester cred more BADASS.
This means optimmizing your experience by tailor proogramming to coil types and resistances, making your coils last longer and vape to their full potential…there’s no better way to do this than with TC.

Sure, it’s a learning curve but the thing is, a half hour messing about with your TCR after installing a coil is worth it if it means that coil will live 2 weeks longer, vape 40% better and provide you with more cumulonimbus action and flavour yummness than you could have otherwise dreamed of.

In this guide I will do my best to explain to you just what temperature control is, what benefits and drawbacks it has and hopefully it will help you determine whether it’s really for you.

What Does Temp Control Prevent?

What Is Temp Control?Have you ever had a dry hit? Ever used an RDA (Rebuildable Dripping Atomizer) and had your vape suddenly taste really nasty due to your cotton drying out? Have you ever had your cotton dry out so much that it went up in flames?

This may not have happened to you but trust me, without some acknowledgement of the TC facts, this is likely to happen to every RDA user sooner or later. I learned the hard way, when someone taking a hit of my vape in a nightclub caused it to burst into an apocalyptic vapeflame display, lol! Dry hits are not just nasty, they are outright dangerous.

Not only is burned cotton the legitimate source of all those painful formaldehyde accusations that initiated vapers spend their lives fending off, it can be pretty catastrophic to your good looks also! Regular drippage is the first step in avoiding such catastrophe, TC is the second line of defence. Hell…scrap that, TC should be your first line of defence.

You might not know this but the movement of e-liquid over your coils actually cools them considerably. Cotton primingOne feature of temperature control, on good, upmarket box mods, is that the chipset in your mod can detect when your coil is getting too hot (due to the absence of liquid) and it will cut off the power to prevent you from torching your cotton…and yourself.

In terms of benefits it’s pretty obvious, since nobody likes the taste of burnt wick and for someone who uses RDA’s a lot, it makes for a good reminder as to when you should refill your atomizer due to a low juice level.

TC sets acts as an autopilot while you vape, using its programming of a coil types boundary temperatures to adjust your wattage as you vape. So your coils won’t overheat and try to kill you!

And Who Is TC For?

Fine, so those of us who’ve been dripping for a while may have learned to keep that cotton soaked but accidents still happen, what with distractions such as people of the opposite sex, alcohol and bad drivers, plus…for beginners to the RDA game, this feature is obviously invaluable.

On top of that, certain wire types, as you’ll learn later in this article, are simply TOO DANGEROUS to use out of TC mode. TC is a standard feature for VARIOUS reasons.

What’s more, if you think your use of regular sub-ohm tanks makes this article irrelevant to you, think again. Cotton burn prevention (a feature of TC) also works in Sub Ohm tanks that use pre-made, replaceable TC compatible coils.

I am sure we’ve all been at that stage with a tank or clearomizer when the coil starts to get really grungy…we taste the burn but life just doesn’t spare us a moment (or the energy) to actually go to the trouble of changing coils.tc celcius farhenheit

When using a coil with your mod’s TC and a little know how, this situation is unlikely to ever occur…and if it does it will have been a long time coming.

Please note. Don’t use anything other than a Nickel, Titanium or Stainless Steel coils when using the temperature control mode on your device. Other coil types will not function correctly…here’s why:

Why TC Won’t Work With Your Nichrome80 and Kanthal Coils

In order to regulate wattage in accordance with each coil’s limits, your mod’s chipset will read minute changes in the resistance for each TC compatible wire type and use this information to predict future changes.

Wiretypes SS, Ti and Ni each have what is known as a workable Temperature Coefficient of Resistance or TCR! This is measured in units of resistance increase per temperature unit, whether Farenheit or Celcius.

Each one of these wiretypes will increase resistance with heat and decrease again once cooled.nichrome kanthal vape wire

Your mod uses this predictability to its advantage by reading those resistance changes and then using the values to determine future changes and set the TC accordingly.

The higher the coil’s TCR (the more it changes as it heats), the more accurate the mod’s TC adjustments will be.

Of the three common TC wire types, Nickel (Ni200) has the highest TC, followed by Titanium (Ti), which has roughly half the coefficient of Nickel, then there’s Stainless Steel (SS) behind that, at about a sixth of Nickel and a third of Titanium. It follows that accuracy will drop proportionally with each of these wire types.temp control vape wires

Kanthal and Nichrome are not on that list because their coefficient is so extremely low.

Because Kanthal (Ka1) and Nichrome (Ni80) barely change at all when heated, they are useless in TC mode

You see, your mod USES resistance readings in coils to determine temp changes, because it has no internal thermostat.

Okay…got it? Only Titanium, Stainless Steel and Nickel are suitable for TC vaping. Some mods will include variations of SS and the other metals. If these metals, only SS can be used outside of TC.

So what does TC mode do?

Basically, TC mode will allow you to vape safely on a given coil type, within boundaries, pre-programmed boundaries. The boundaries are set in degrees celsius or Fahrenheit. Vaping outside these bounds will be limited by power drops or cut outs and basically, you and your coil will be kept safe from dry hits and a world of pain.

Nickel tcOne of the best things about TC is that it will account for your vape-idiosyncrasies, such as extended hits or chainvaping to ensure that you stay within the limits of what is safe for you and your chosen coil type. It does this by constantly adjusting power output while you vape, using your temp control parameters.

TC acts as an invaluable safety feature and should be USED AND NOT IGNORED.

Setting Up Your TC

Okay…now, depending on the type of mod you’re using, you may or may not be able to adjust wattage directly while in TC mode. So, just in case you have this type of mod, I’ll explain set up with you in mind.

If your mod allows in TC wattage adjust, good for you! That means you’ll have the added bonus of playing around with your wattage once you’ve set your TC.temp control guide watttage

The point is that TC adjusts power output anyway so it’s probably best to think in terms of Celcius or Fahrenheit when vaping TC, rather than wattage.

Hopefully, you’ll be able to use this information to work your way around the unique chipset and programming of your vape mod.

First up…Find the perfect wattage for your coil. If using a premade coilhead on an enclosed atty, read the recommended wattages printed on the coil head and cycle through them slowly until you find the wattage that’s best for you…it needn’t be perfect because the temp control is where you’ll get to fine tune your vape within that wattage range.

If using an RDA…check out the ‘observing your coils’ section in our Power/Temp Curve article and follow this method to find your perfect wattage.

Second up…Once wattage is set, use your knowledge of your coil type or material to enter into the TC mode that’s relevant, ie: Ti, Ni or SS.

Most mods will now place you at a pre-programmed wattage and a low-temperature setting. If, for some reason, your mod doesn’t start you at a low setting, we suggest you scroll down, just in case. It’s better to be safe than sorry, any damn day.

wattage adjust tc

Third up…Now it’s time to start exploring, by starting low, increasing in increments of 5 or ten degrees and then finer tuning when you encounter a stretch that tastes and vapes good.

You may find that certain juices favour a hotter vape. You may find that lowering the temp brings out the best in others. The point is that you’ve added more variables to the mix, your vaping experience has now been injected with potential.

Stainless Steel

Every wire type has its benefits and drawbacks. When it comes to SS, the benefits are manifold.

Firstly, SS operates just fine in power mode because of its extreme durability under heat. SS wires require massive temps before the metal begins to oxidise, making them safer for you to inhale on, willy-nilly, than other varieties.stainless steel vape wire

So…this means that SS, of the three wire types, is the safest and best when you’re new to TC, because you can take it in to VW or VV mode without the risk of inhaling anything noxious by accident.

The second benefit is even more interesting.

Because SS, which is usually seen in its SS316-L variety in coiling wire, has the highest resistivity of the three common TC wiretypes, it allows for more complex, alien, competition and flavour coils to be built without bringing the resistance so far down that you aren’t going to be able to power them up without overheating your device or making it cut out altogether.

So…if building fancy coils is your game, SS coils may well before you. The trouble comes in with its TCR. It’s not as sensitive to heat as other variations and so, unless you have one of the more sensitive mods on the market, your TC might not be very accurate. Nevertheless, the fact that the wire is so safe makes up for this.

I have found that, given the relative safety and the high resistance of SS wire, it is by far the MOST fun to play with when building funky coils…and in spite of relative inaccuracy, I also find it the most useful AND SAFE when getting used to the idea of vaping at different temperatures. SS is recommended for newcomers to TC.

Nickel

Nickel-ni200, is by far the most popular wire type to play with in TCM. Not only is it cheap AF, it is also pretty darn accurate in TC. It’s a damn site more accurate, due to its much higher TCR, than SS, put it that way.

When it comes to building fancy flavour wires that you could post on Instagram…you might find that Ni lets you down…the resistance is just too low. That’s why fancy coils that do have nickel in them tend to be mixed with SS to up the resistance a bit.

Nickel Tempered Ni200 From Stealth Vape
Nickel’s low resistance, extreme pliability and high TCR combine to make a wire that, at least when you start vaping on it, requires “breaking in.” It has a tendency to change resistance massively within the first burns so there’s no point locking your resistance until you’ve adequately broken the coils in.

Now, since Nickel makes some seriously TOXIC oxides in the upper temp levels, it is not advised that you play around with it in a reckless fashion. NiO2 for example…is so damn unfriendly that I suggest you burn this into your consciousness:Nickel should only be vaped in TC mode.

The oxides formed by Nickel at high temperatures are anything but safe and what’s more, when you pulse Ni coils, which you should never do…a layer of these oxides is formed on the coil surface, which you will then inhale with your first hit so PLEASE, don’t pulse em!

Nickel, however, is absolutely spectacular for using in TC…but you gotta do it right and remember, DON’T PULSE AND DO START LOW!

It does take some getting used to and one of the most important things is that you need to space your coil wraps evenly. Since you can’t dry burn Nickel like you would Kanthal in order to pinch your coils it is trickier.

If you are interested in working with Nickel wire then do go to Stealthvape and purchase their Tempered Ni200 Wire because it is stronger and easier to work with.

When fitting Nickel wire you do need to make absolutely sure that the wire is firmly secured. If the wire isn’t secured properly the device will show inaccurate results and you do require accuracy for temperature control to function correctly.

The problem is that being very soft Nickel tends to break quite easily when screwing down Philips screws so it is advisable that you only build Nickel coils on RTA’s and RDA’s that have grub screws because they don’t tend to snap the wire.

Spacing your coils can either be done on a coiling tool by hand or for better results it is advisable to use a typical bolt that has evenly spaced threading. Make sure the bolt is the correct diameter according to the coil you wish to make and then wrap you nickel in the tracks of the bolt’s threading. Believe me, it makes things much easier.

Wicking an Ni200 coil is a little different.

The key thing I will say here is that “less is more”. You ideally want to use far less cotton than you would typically would for a Kanthal build.

It will take a little experimenting for you to get the right results but one thing to note is that if your device is having hissy fits stating “Temperature Protect” with a new Ni200 coil that has been wicked and juiced then too much cotton is the typical culprit.tc coil selection

Titanium

With about half the TCR of Ni and a way higher TCR than SS, Ti is the middle ground. Ti also rocks a low enough resistivity to afford you a little creative flare when building, provided you’re strong as hell, coz it’s a hard wire to bend. Unfortunately, price makes it inaccessible to most of us.

Stealth Vape Titanium Wire
One of the greatest features of Ti wire is, as you can imagine, the durability of your build once you’ve built it. Not only will your fancy coiling hold its shape, it will make the build into a tricky deck with ease.

We’ve all heard that incredibly irritating song and I think most of us have felt the allure of shiny titanium coiling wire but the fact is, you’re not really missing anything here, well…that’s what I like to tell myself.

Not only is the stuff super pricey but there are drawbacks to Titanium coils since there is the potential to give off Titanium Dioxide at extreme temperatures.

Titanium is not as widely used as Nickel for the time being and rather than writing a massive amount about it here you would be better served by reading the following articles:

If you do intend to work with Titanium then please do make sure to buy only Medical Grade Titanium which can be found at Stealthvape.

Also, pulse it only at the lowest wattages, under 20W and never allow it to glow when pulsing or you will risk a toxic oxide build up. AND NEVER USE OUT OF TCM, for goodness sake.

How Does TC Benefit Flavour?

Have you ever found that you hit the sweet spot with your vape, where it just tastes and vapes way better? Some coils work better at a specific wattage and sometimes the juice just tastes that little bit better at a certain temperature, noticeably when the coil has been heated several times in a row.flavour and vaping

One of the most useful features of temperature control is that it allows for flavour adjustment, refinement and enrichment. Think of the way coffee smells when it’s being roasted and get the idea. Some flavours sing when they are warmed, some…like natural fruits, become sweet and even sickly.

Temp control not only allows you to set the wattage that best suit’s your coil, juice consistency and flavour, it lets you go a step further.

Temp control lets you adjust the temperature at which your juice is being vaped…a higher temp might bring out nuances of flavour you never thought possible with a particular juice. On the other end, a lower temp could stop you burning your juice and ruining the subtler notes in the flavour. Indeed, you’ll find that keeping temp down on a minty juice enhances the cooling effect.

I actually discovered the joys of temp control by using it for flavour enrichment alone.

By also allowing the adjustment of temperature you can get a lot more refinement and flexibility to your vape than you would with Kanthal coils and regular wattage adjustment.

At the end of the day the simplest way to put it is like this:

Sometimes juices just don’t taste right and adjusting the wattage up or down is not doing the job… but by tweaking the actual temperature you can get far better results.

Don’t knock it until you’ve tried it! What I’m saying is, temperature control could help you to make the most of those juices you buy but haven’t really developed a taste for!

Resistance Lock On Supported Devices

A very useful feature of many new vape mods that feature temperature control is the ability to lock the resistance. How this works is typically by screwing on a new atomizer and then using whatever control your particular mod uses to lock it in.This ensures that the temperature control will always work accurately….it’s known as BASE RESISTANCE, which is the resistance of that particular coil at room temperature.

Put room temperature atomizers on your mod before enabling temperature control

This one is pretty much common sense but some people still fall foul of it. If you want your device to give you an accurate result when you screw on your atomizer please make sure it is completely cool.

An atomizer that has been used on another temperature control device which has been heated up will mean you get the wrong base temperature for it on a new device and this can cause you lots of issues.

Final Words

This temp control guide has really been intended as a primer for vapers looking to get more information on TC but not just that, I want it to inspire you to use your TC.

Not only will your TC help keep you and your gear safe and functional, it will help you to bond with your mod and get the most out of your coils and your juices. Give it a try, it really is worth it.

Greetings Vapers! I’m a 34 year old writer, editor and massive vaping enthusiast based in the beautiful Helderberg region in South Africa. My passion for vaping has steadily grown in the past 4 years since I started vaping in earnest (as has my scorn for smoking). See, I tried vaping years before that but returned to cancer sticks after a bad experience (PG sensitivity). When I finally got back on the vaping train I decided to make it my business to educate beginners and vapers in general, so that they don’t jump to the conclusions that I did. I visualise a world without cigarettes…not just for health reasons: I’m tired of picking thousands of cigarette butts up off my lawn every morning, tossed over the wall by passers by. I can’t believe I used to be one of those people!

  1. Is it possible to have temp control for ceramic coils? How does having ceramic around a metal coil effect the resistance/ability to do temperature control? I’m not interested in subohm or drip, just want to be sure that I’m vaping prefilled cartridges at my desired temperature, without having to do calculations every time.

    • While I haven’t personally tried TC comaptible ceramic coils the likes of the Vaporesso cCell Ceramic Ni200 can be used for TC. You will need to ensure the wire material is TC compatible of course.

      As for ceramic effecting the ability of TC I couldn’t tell you. May be best to get in touch with Vaporesso with that question.

  2. Hello fellow vapers,

    I am a return vaper. I used to vape to quit, which I did for six months and then one cigarette lead to another, and I started smoking again. Now, I am back to vaping and I bought the great Aspire Archon mod, which is in my opinion incredible! The reason though I am reaching out is because I am switching to TC vaping. I am using the eleaf Ello which again in my opinion it’s a great atomizer. The thing is, as far as my knowledge goes, it’s not very suitable for TC vaping. But until now I very satisfied. The only thing I don’t understand it’s the TCR setting found in the manual setting for TC. Can anyone help me with that?

    • Hey Michael,

      Good to hear you’re giving vaping another shot!

      OK.. regarding TCR.. Rather than writing a lengthy reply here, be best to check out this TCR guide here.

      Should help explain things! Thanks

  3. I recently got the Smok Alien Baby AL85 kit that came with the Baby Beast tank and 2 stainless steel coils. I tried wattage control first but found TC much better because the hits are much more consistent. SS is awesome for TC mode because it’s resistance changes very little as it heats up. I’ve found this coil has almost no effect on the flavour at all. But be sure your mod supports SS in TC mode before you try it.

  4. I just bought a Kimsun TC40W Mini .
    It didn’t come with a tank so i’m now trying to find a tank and probably some coils to use with it.
    Any idea wher i could get a tank/coils to use with this mini mod ?
    I’m in London U.K.
    Previously i was using a T22 battery with a Nautilus mini tank or peakomizer v2.o.
    and also giant evod batteries with boge cartdriges or aspire mini nova tanks.

    • Hi Chris,

      You can use the Nautilus Mini and Peakomizer. The Kimsun TC40 has a 510 thread connection that is the most common thread type available.

      If you are looking for something different then I could recommend the Aspire Nautilus 2, the latest Nautilus MTL tank but a very good one at that.

      If you had something else in mind though please let me know what style of vape you are looking for and I’ll try and advise further.

      One thing to keep in mind when choosing a tank. As you will know the Kimsun TC40 is a tiny mod. Just double check width of the tank and width of the MOD to make sure the tank isn’t way to big or overhangs the mod.

      Let me know.

      Cheers

      Jonny

  5. So I’ve started using an Innokin Cool fire IV TC 100 with iSub V TC Tank and stainless steel coil.
    My question is if I am using it in temperature control mode (set at 220 degrees C) is the wattage set by default? The reading on the screen says 100W, but is this just the maximum wattage?
    Just trying to figure out if I’m better using Watts or Temp

    • Hi Ian,

      The wattage shown when in temp control is know as ‘ramp up’ wattage. In theory the higher the setting the quicker your coils will heat when pressing the fire button.

      You can change this to suit your needs so it’s worth having a play around with it.

      As Innokin explains it for the TC100

      “PreBoost Ramp-Up Technology: What it does:
      Select the wattage the AETHON chip will use to heat the coil to the target temperature.

      Press and hold the “ ” power button and “-” button for 3 seconds to enter PreBoost RampUp Wattage selection mode.

      The PreBoost RampUp setting in the lower left corner will flash. Press the “+” or “-” buttons to cycle from 5 – 100W
      and press the “ ” button to set the RampUp wattage.

      Flavor and vapor production will change depending on your selection; this allows you to tailor your vaping experience even further than just wattage or temperature.

      The optimal Ramp Up wattage setting will vary according to the type of coil and tank that you are using. Experience more flavors and better vapor from your favorite eliquids”

      As you are probably aware you can use stainless steel coils in wattage mode as well as TC mod. These are the only TC coils that can be used in wattage mode.

      As you say it’s more just figuring out what your preferred mode and setting are so have a little play around with it.

      Let us know how you get on!

  6. I have been using TC for over 1 year now and will never go back to wattage mode. many vapers are too quick to dismiss TC and don’t see the benefits which have been listed here. I think the article should have more information on SS, I find that the best metal for TC and is easier to build your own coils with than Ti or Ni.

  7. Very informative, thanks. I still have a problem with Ti wire that constantly shoot. And for nickel hear all kinds of stories about the fumes, so I’m in a dilemma, although it does have the best vape.

  8. Nice blog and nice site. Just jumped in by a giveaway, but I will put this on my Speed Dial. This blog entry about TC was smack, dab and right in the middle since I just bought my first TC boxmod 14 days ago, and haven’t really tried it that much (eVIC Mini/Uwell Crown)…
    Informative!

    Merry X-mas and happy vaping!
