Thanks for the message. could you shed the light on how to count wraps? Hi, very grateful with your calculator here. Happy Vaping! If your building for a single deck/coil then select single and specify what you want your resistance to be. Your combined resistance is 0.6ohms so no problem there. Did you dry burn your coil to make sure there were no hotspots? I am struggling to use this and it is so difficult to coil. One day a friend gave me an MTL device and the smoking just stopped. Please guide. 100ml is a LOT of juice!! by the number of segments, The 22AWG wire is sold by infraredheaters in, Using the formula C = Π * D. The diameter is measured between the Learn how your comment data is processed. The default is set to 5mm total (2.5mm per leg). Hope this helps Ben! Thanks for the calculators, they work fine. We’re also going to be posting a review of the Aegis Boost and RBA soon. The outer wrap of a Clapton is fairly insignificant with respect to the core wrap in terms of resistance. Have a great day! I recently purchased Geekvape Twisted 26AWGx2 Kanthal A1 wire to experiment my builds with. Hope this helps! Hope this helps! 5.0 out of 5 stars 8. Choosing between vertical and horizontal coils will often depend on your atomiser, the position and shape of your air holes and the layout of the build deck. Once you calculate how many wraps you need, it’s a simple process of tightly wrapping the wire around your drill bit or coil jig. Simply select ‘Custom’ and the menu will change allowing you to input the wire diameter and resistance per meter of your specific wire type. To wrap a coil, you’ll need either a drill bit, a screwdriver or (ideally!) It is the standard measurement for the thickness of the wire. Congrats on getting the OBS Cube with the MTL Engine Tank, that’s a great little set-up! © Vaping Hardware 2015 - 2020, All Rights Reserved. You’re drawing 38Amps from a Samsung 25R 18650 battery which is rated at 25Amps. This figured is derived from Ohms Law. This should help prevent any nasty surprises or a ‘short’ when you fire the mod for the first time. If you’ve not already done so then take a look at our calculator guide and coil building guide. thanks, Hi Chip, thanks for the feedback! I am looking for a replacement for my current coil app because it’s no longer on iOS I make coils such as staggered fused Clapton, alien & Clapton out of more than one type of wire how long before we’ll see them added to the list thanks We’d usually suggest sticking to around 6 wraps as this will give you a good cross sectional surface area with decent flavor. By inputting just the core wire profile and AWG you’ll be getting a roughly similar result. If you’re using a regulated mod you can check the correct battery current drain using our Battery Amp Draw/Drain Calculator. Thanks Richard, well as you say the only obvious thing is more wick, other than that I can’t say I noticed any other difference. Your coil build (deck resistance) at 0.11ohms is too low. just checking before I blow my face off!!!!!! We don’t have an option for making Clapton coils just yet but this is coming soon! Hope that helps. This can really affect the vapor produced. I felt all the burnt stuff and yeah, just realized that smoking is a horrible mistake. Thanks for the comment I haven’t personally built on a minifit device before but the problem you’re describing sounds like a wicking issue. Both Macro and Micro are forms of ‘contact’ coils, which basically mean they’re tightly wrapped, with each coil wrap touching those on either side of it. I think you’re getting slightly confused here between voltage and wattage. This I am usually getting 0,22 to 0,25 Ohm with 6 to 7 wraps in a dual build deck, 3 mm inner coil and with legs cut off between 4,5 and 5 using Geek Vape’s N80, 24ga + 36ga. Good luck with coil building. As with any coil you build, it’s always vital that you test it before you fire it. It’s on the spot! Hi Richard, great calculator and posts! Thanks for the calc, it’s incredibly helpful. However they didnt have any more fused clapton wire so I got the 22G Ka A-1 and tried dual and found this calculator to be very accurate. These are direct replacement heaters for DME hot runner extruder part numbers. Keep trying though as you will get there. Ultimately though you can experiment with the wattage you’re using on a regulated mod and see what works best for you. Hello If you're making a coil, you'll need to calculate the resistance needed and from that it's a simple matter of calulating the length. Your twisted kanthal of 24AWG at 6/7 wraps on a dual build deck gives you an overall resistance of 0.21ohm, meaning each coil is around 0.42ohms. Your email address will not be published. A full wrap refers to the coil legs pointing in opposite directions. Does that mean mm of length…lmk please. Be sure to have a read through our wicking guide too. Thanks for your comment and I hope the following helps. I am still learning what I like with the Kanthal wire but if my build is 0.23 on the dual and the single was 0.34 which would technically use less power on the battery? But am experimenting on my own builds. Use an Ohm reader to make sure that the resistance is roughly where you want it. 2) Alternatively, if you’re using a regulated mod the resistance of your coil doesn’t affect the drain on your battery. The total tail lead length will be the sum of the two legs, so if you’re cutting each leg using a coil tool to 4.5-5mm, the total lead length will be 9-10mm. What’s the current battery drain? What’s my battery ratted for? and a pair of cutters. Thanks for the comment. What is a Mechanical Mod? Should I test the resistance of my coil before firing it? The surface area of both coils will be approx. As the name suggests, this is simply a coil placed flat on your build deck, running between the deck posts. If you’re sure both coils are of equal resistance, make sure your coil leads are of equal length and attached securely. HVAC,Sum, Total Water Heating Coil Energy[J] HVAC,Average,Total Water Heating Coil Rate[W] HVAC,Average,Water Heating Coil U-factor Times Area [W] Total Water Heating Coil Energy (J) Total Water Heating Coil Energy is the total amount of heat transfer taking place in the coil at the operating conditions. However I shall continue to build 3mm coils as the extra wick holding more juice seems to last longer. Just keep in mind, above 10 wraps you start to experience potential slower ramp up speed (longer time to heat your coil) which obviously will drain your battery faster. The smaller diameter will obviously result in a thinner wick meaning less absorption of e-juice. It says on your website My current battery drain is 38a. So let’s take your intuition about current draw to its logical conclusion. Hi Ahmed, thanks for your comment I’ve not tried the Mini Fit personally but I’ve tried a few other Vape Pod devices and I find they all differ slightly in performance. Is the Vaping Power @ 4.2v the recommended wattage to use when vaping my desired build? It’s great to hear that you’ve had such success with vaping. Hope this information helps Simba and any more questions feel free to get in touch! Please please give in SI units. I am completely new to coil building and was able to build my first dual coils and I think they turned out alright. Nickel NI200 and Titanium wire can both be used in Temperature Control mode. Hi everyone I need to heat up an area 0.5m^3 (100cm x 100cm x 50cm). Hi Tony, this is usually caused by one of three problems… Either your coils are slightly different resistance, you’ve got heat spots or your coil leads aren’t fixed into your deck posts properly. Its just single round or fused! as the cube is variable wattage can I safely use on the 1-80w range? I use a coil cutting tool and cut each leg to +/- 4.5-5mm. As long as you know how to wick properly of course…. Personally, we think a great starting range would be something like 0.5ohms to 1ohm. The total wattage is calculated using the amount of airflow (SCFM) and the temperature rise (∆T) desired. However, this won’t necessarily fix the problem you’ve described. I am completely new to building having just moved up from a Smok RPM40. There’s no reason you can’t build with more coil wraps than this, however more wraps doesn’t necessarily guarantee better flavour. These will really help you understand the process of building a coil and using our calculator. Your vaping power at this build will be approx. Maybe you could try reducing the wattage you vape at or increasing your coil resistance….vape juice isn’t too cheap these days, especially if you don’t mix your own e-juice. is it safe to chain vape between 60-80W? I’m going for a 0.3 ohm coil using 28G Kanthal A1. FREE Shipping on orders over $25 shipped by Amazon. When I’m making a parallel coil, is the number of wraps the number of times I wrap the coil jig? I don’t know what I am doing wrong here. Can you suggest the best wattage range for that setting? the same and so will the ramp up speed (time it takes your coil to fully heat). Hope this helps! Hi, how to use this calculator for fused clapton wire 28gax2 +38ga in order to build mtl coil? This is never more important than when using an unregulated mod (Mechanical), a direct short to ground/earth could be dangerous. A lot of the positive feedback we get for our coil wrap calculator points to it being user friendly while covering the majority of options most users need. I usually use pre-built coils and use Nano-Aliens +/-0.19 Ohms dual. Hope this helps. Heating Element Guidance The following calculations give a guide to selecting an electrical resistance wire for your application All information is given for guidance purposes only. Coil lengths can be much longer than those shown depending on coil … I want one battery to run all day, so the power required is low, resistance is 2.23. The resistance, 0.21, showed too low for my battery with 20A maximum current with my variable Smok T-Priv and an atomizer of Geekvape Avocado 24mm. I’m new on diy coils and a really dumb one. A workaround you can use on our calculator would be to select either Kanthal or N80 wire in the wire type and parallel 2 strand in the wire profile. Does this mean that I should wrap my coils 19/18 on both or it’s the total for both coils? is there any advantage / disadvantage (Flavour etc) building a coil with 3mm diameter and 1 less wrap again aiming for about 1.2 ohm ? Thank you for the great feedback, really glad you like the calculator. If one knows the amount of heat required from a coil, the EAT and LAT; and want to calculate the amount of airflow required, the equation becomes: SCFM = Q / 1.085 * (LAT - EAT) Ideally you want around 6 wraps per coil to be able to fit in between the deck posts. Many thanks again. Any problems, give us a shout! This figure allows comparison between ovens with different sizes and power outputs, The outer loop is at the centre of a 2" band around the board, The length of each individual segment used during layout, Please note that these are "ideal world" calculations. This will be fine as long as you don’t vape higher than 110W using your 20A batteries. hi Richard, thanks for the reply! I usually aim for anywhere between 0.19-0.25 ohms on my vape, however, I am not sure exactly what the tail lead length (total) will be. I tried to recoil using kanthal A1 32 awg. The U-factor is usually developed from past experience.T is a difference in temperature. Please help me If i am using a regular ni80 32 ga wire, how many wraps over which diameter to give me same hit like mini fit ready made one?? On the other hand, wattage refers to the power that you want to vape at. A huuuge thumbs up and I hope to see an app in the apple app store soon! Hello Richard, thanks a lot for providing the calculator. The average number of wraps on a vape coil is anywhere from 6-10 wraps for a good result. open circuit, you have infinite current. Stainless Steel (316) can be used in either Variable Wattage or Temperature Control (TC) mode. Hi Jimmy, not sure exactly what you’re asking. In reply to your question there are two possible scenarios: 1) If you’re using an unregulated mod (mechanical mod) a 0.23ohm coil will draw 18.26A and a 0.34ohm coil will draw 12.35A. In terms of the basics, you’ll need a length of resistance wire, a screwdriver ( or drill bit!) Thanks for your comment and glad you found the calculator useful! Heating Coil - Water Outputs. To give you an approximate answer of wraps needed when using Clapton wire, input the gauge of the inner or core wire and ignore the gauge of the thinner wire wrapping around the core. My understanding of Steam Engine’s recommended wattage of 45 is a suggested wattage to set your regulated mod to with the coil build you’ve input. Thanks for the comment and we’re really glad you like the calculator. If you’re using a regulated mod you can select whatever power you want via the wattage settings on your device. 5) If you’re referring to the ‘Current Drain from Battery’ in our results section being higher than your 20A max current batteries, that only refers to the current being drawn if you’re using an unregulated mod. Heat spots are a simple fix. If you’ve had any problems with the Coil Wrap Calculator, please see the user guide here. Basically this is just the size of the ‘inside’ of your coil. Happy vaping Simba , hi richard , Conclusion: Converting a 110v/4seg oven to supply the same watts using 220v will use only half the amps, but it will take 4 times the length of nicrome wire, When I put it in my mod it will not vape at any wattage. This site uses Akismet to reduce spam. Personally, we prefer this method as we notice less ‘spitback’ from these when compared with vertical coils. Yes, our calculator will work out the required wraps for any type of wire. The 19/18 rounded half wraps that shows on our calculator means you’d need to wrap both your coils this amount of times. However, I saw on a YouTube video about building, that we should aim for 8-10wraps, no more. If you choose to use 30 awg wire with the same number of wraps, the surface area of your coil will increase and provide slightly more vapor. It really is down to individual preference, how you vape and what size coil will fit into your RBA deck. 2) Rounded half wraps means the coil legs point in the same direction. 1 combines all the factors that determine the surface area of the heat transfer device.A = Q/UT. thanks bud. Instead it’s the wattage you vape at that determines the current drain of the battery. Whatever build you’re after, our Coil Wrap Calculator has you covered! We usually find this number leaves you with enough of a leg to easily fit the coil into the deck post, however you can alter this number to suit your needs. Or do I half it because of the two wires? Most heaters use identical coils throughout the circuit to ensure that the load is balanced. This will give you a 1.4ohm vape coil which I think should roughly mimic the vape experience on a Vape Pod device. I am using the Dovpo-Blotto RTA on my Vaporesso Gen and have a few questions. It’s a nice setup you’re using too, both the mod and tank are great choices! Am I safe? Hi, I’m using an aegis x zues x rta dual coil at 0.12 resistance while using a molicel p26a (25A) per battery test review. Thanks for great feedback and glad you like the calculator. Also on a regulated mod remember the coil resistance doesn’t determine the current drain, it’s the wattage and voltage. To perform as a heating element the tape or wire must resist the flow of electricity. We’re really happy you like the calculator and it’s always nice to hear it’s easy to use. Russell. Hi Darwin, thanks for the feedback, we really appreciate it We’re actually hoping to have a coil wrap calculator app ready for release in the near future! I used your calculator (btw, it’s soo cool!)

This is the power your mod will produce based on the coil you’ve built. (This is an estimation.) 4) Your Smok T Priv is a regulated dual battery mod so the coil resistance is not important, it’s the wattage you vape at that determines the current being drawn from your batteries. We’ve got a section in our coil building guide that covers potential problems with a coil. I wanna use abit less juice as I am averaging 100ML in 2 days ooF. Coil Building Tips & Tricks – How to Build a Vape Coil in 6 Easy Steps! If we’re feeling in the mood, we usually wrap a few coils in one sitting so we’ve got a couple to hand. What does 'Current Drain from Battery' mean? I just discovered this twisted kanthal wires. I would also suggest playing around with different deck configurations, perhaps a dual coil setup… Good luck and happy building! The resistance is determined by the number of wraps, the diameter of the wire and circumference of the wrap. i do not understand what the tail lead length is. However, this method was the standard back in the early days of DIY vape coil building and is a design we still use to this day. Hope this helps Max. The tail lead length is the total length of the two ends. However, we only recommend products we've tried and tested! Use our power, resistance and current calculator to check what build is safe for the CDR rating of any battery. sometimes i got the same resistance with bit different wraps Hope this helps Ronald, any problems feel free to let us know. Full wraps means the coil legs are pointing in the opposite direction. If you’ve now moved on to building your own vape coils on an RDA or RBA, the best advice I can give is to experiment with a few different coil builds to find out what works best for you. BTU Calculator AC BTU Calculator. Are the individual wraps on the coil touching each other (compressed) or spaced? Your set-up is NOT SAFE. If you’re heating the coil at 5W then you probably won’t produce much vapor. 2 x 3ohm coils will be 1.5ohm deck resistance. i.e. Again, have a play around with your coil diameter, target resistance and vape wire gauge to see what suits you best! Step 1, 1 Know the resistance of the element should be this can be calculated using known values:[1] X Research source R = (V x V) / P [Where V is the voltage powering the element, P is the power the element uses and R is the resistance.] Specialized calculator for atomizer coils. I understand that Kanthal A1 with 4 coils would produce around 1.2ohms? To give you a very close result you can just select ‘dual strand’ and input the 28 AWG inner core wires. I’m using Samsung 18650 green battery on a mech mod and have a .11ohm dual parallel build just wanna make sure I’m not drawing too much power. If you’re building with Kanthal A1 32AWG and you want a target resistance of 1.4ohms, you’ll want a 2mm inner coil diameter and a total of 3 full wraps. What is the 'Target Resistance' and 'Build Deck Configuration'? How come with Steam Engine the outcome for a 26 AWG Kanthal, dual coil aiming for 0,5 Ohm, 3 mm diameter I get 45 Watts for mod-settings and with Coil Wrap Calculator the same build gives 35.28 Watts? As for whether you can use the Mod safely, the internal battery will work on the max wattage it’s been designed for so you’re good to go. If i used 30 awg instead, is it gonna give more flavor and vapor؟. Spot on calculations! We Are the Best Choice for Heating Elements . can calculate the coiled inches needed, This figure can work out to an amazingly large value, You will notice this equals the end-to-end resistance, Each of the segments should have a resistance as close as possible to.

If you’re completely new to the world of DIY coil building then you might want to take a look at our coil building and coil wicking tutorials. Please let us know what you find the best wattage to be though. The norm for stock coils, this is basically a standing coil situated in the centre of your build deck reaching toward the top of your atomiser. I purchased a Cube w/ Engine MTL tank. Hopefully the info below answers all your questions…. Depending on the height of the oven and the angle of the side boards, the base will be We are looking to add this in the future however. I’ll definitely install it. That battery is not designed to draw that much current. Question is, a heating tank ( approx 1.2m tall and 0.86m Diameter) will have a flow of 1000kg per hour of oil running through. This is the total resistance required to draw, Using the formula for parallel resistance you can work backwards to find In your case, the ‘6/5’ relates to 5 wraps counted on one side and 6 on the other. witch could become expensive. In terms of the number of coil wraps, we usually recommend somewhere in the ball park of 6-8. If you’d like to share this calculator then please hit one of the share buttons below. Hi sir, im using minifit. What does this mean? They suggested 32 nichrome80. With a 1.2 ohm coil you’ll probably be looking at around 15W – 25W for a satisfying vape but it really depends on personal preference. Steam pressure onto the control valve = 2.6 bar g (3.6 bar a) Critical pressure drop (CPD) will occur across the control valve during start-up, therefore the minimum steam pressure in the heating coil should be taken as 58% of … My best advice would be to try it and see if you find any noticeable difference. Part 1 Calculate the average steam mass flowrate during start-up. If you’re building a dual coil/deck configuration, then select dual and specify the overall deck resistance. as long as the potentiometers adds to the heat produced, a fancy triac dimmer may actually be more efficient in this case, even if it has only a fraction of the conductance inefficiency. Get it as soon as Fri, Dec 4. Why would one side of a two coil build heat up much slower than the other? A dual battery mod using the same 25A batteries is good up to 140 watts. When you wind your coil, this is the ‘clipped’ length of the open straight ends of the coil that are inserted into the deck posts of your tank. They should be kept to a minimum. the proposed Vaping Power from resaults,is current up there, or from there; Extruder and plastic molding component replacement coil … 29. Although you don’t actually NEED that much to build a coil, there are literally dozens of tools, supplies and gadgets we could list here! Disclaimer... As Amazon Associates we earn a commission from qualifying purchases. E.g. Your question is a good one and the answer is a little open-ended. thanks for providing the calculator , they work fine. Another question is regarding the wraps. It’s important to note that the resistance of the coil has no relevance when using a regulated mod (like the Aegis you’re using). Coil Heater Features. Kanthal A1 wire, but the tail lead length is always put on 5 in your website, is it the normal? This method will give you a very fairly close result. (W=SCFM∙∆T /3) The wattage of each coil is the total wattage divided by the number of coils in the circuit. This depends on the layout of your build deck and how the coils fit in to the posts. Equation No. Hi Nichole, thanks for the comment You don’t need to half the number of wraps. This also serves to confirm that to measure the straight length of one coil, we must use the centre of the wire as the diameter ; Coiled length needed: 26.889 : 107.556: 60.500 : 26.889 : coiled in: Using the end-to-end resistance, and the ohms per coiled inch, we can calculate the coiled inches needed : 68.298 : 273.191: 153.67: 68.298 : coiled cm Hope this helps Let us know if you have any problems. I use your calculator result to fit my Aegis Boost RBA, aiming for 1.2-1.3 ohms for my 50 mg SaltNic. As we always suggest, start off on a low wattage (15W) and adjust upwards until you find your sweet spot! Our ‘Power, Resistance and Current Calculator‘ lets you quickly work out the drain on your battery when using a mechanical mod. I’m vaping with 14 wraps on 30gauge ni80, single coil. big thanks. Hope this helps Jan. Why cant i calculate clapton? This is also ideal for most build deck sizes! This is the first time that I’ve used your site for building and find it much easier to use than most that I’ve tried. For infinite resistance, i.e. It’s important you stick within the safe range your device can handle! Unfortunately our calculator doesn’t currently allow for exact calculations on a Clapton wire type, but we will be adding this in the very near future. I’ve just built my first coil using 28awg and 2.5mm diameter with A1 Kanthal , I was aiming for about 1.2 ohm and got 1.15 so I was happy enough with that for a first go. This micro coil is any type of coil with an inner diameter of less than 2mm. the wire, with each segment decapitating 1.3 times the power as compared to a 110/4 oven. This information can often be found on the wire wheel or manufacturer’s specifications. It could also be worth experimenting with your wicking method as well. Manufacturer of Heating Element - Coil Heating Element, Bain Marie Heating Element, Mica Strip Heating Element and Water Heater Element offered by … Great job. Hope this helps, please let us know how you get on! These coils have gained popularity, due to the improved airflow and flavor as more of the coil surface area is in contact with the wick. Just be careful not to go too high! The vaping power is derived from the coil build resistance and assumed full battery charge of 4.2V (as per ohm’s law) Hope this helps! SWG is the UK equivalent but is not used. Would anybody know of any formulas I could use to calculate what wattage heating element id need to heat this area up to 100 degrees C within say 30 minutes. Induction heating coil design: Coupling is the transfer of energy that occurs in the space between the heating portion of the coil and the workpiece. We alternate between pre-built coils and wrapping our own. Thanks for the comment and really glad you like the calculator! Stainless Steel (316) can be used in either Temperature Control or Variable Wattage mode. Used predominantly in the duct heating industry, open coil elements have open circuits that heat air directly from the suspended resistive coils. Thanks Simba, really glad you like the calculator! Heaters can be coiled to lengths greater than shown with or without wattage profiling. I’m a newbie in vaping, just stopped a 20 years smoking span. The size of whatever you use dictates the inner coil diameter. To obtain the elements resistance at room temperature, divide the resistance at operating temperature by the temperature resistance factor shown below: Where : F = Temperature-Resistance Factor R t = Element resistance at operating temperature (Ohms) R = Element resistance at 20°C (Ohms) I’m using the single coil rba on the Aegis Boost at 13 watts. The thinner wire wrapping around the core wires only changes the number of wraps needed by a fractional amount. To make life easier, there are plenty of coil building kits available with everything you could need and then some! Your email address will not be published. Quick tip though; a good pair of clean nail clippers work just as well! The internal battery will easily cope with 7A drain. Thank you very much! However, this is always dependent on the mod and/or tank you’re using. (An example calculation is shown in the tips section)Step 2, Now we know what resistance we are looking for we can check the element.Step 3, 3 … Standard Coil Sizes. Instead, the wattage you choose to vape affects how much power you draw from your battery. Wolf. Anything on that scale should give you great flavor and vapor! Coil calculation is roughly this: pi = 3.14 Preferred outside diameter of coil = 0.25" Each coil will use 3.14 * 0.25 = 0.785" of wire. Some people now consider this ‘old hat’ as the popularity of vertical coils has increased. This is by far the best, most simple and accurate coil calc I’ve had the pleasure using! Obviously your intuition is wrong here. Any advice. Thanks for your comment. Hope this helps Ben, happy building and vaping! Above all, it’s best to just use whatever you find works best for you. This is the current being drained from your battery based on the coil you’ve built. Likewise, for a Fused Clapton which has two cores and an outer wrap, input the two core wire profiles and AWG by selecting ‘Round Parallel 2 Strand’. You can see how that vapes and increase your wattage slowly up to around 15W to find your ideal sweet spot. If your result showed 158.30 wraps then unfortunately you’re trying to build a coil that’s impossible to fit in a vape tank. The tail lead length simply refers to the ‘legs’ of the coil I.e the wire showing either side of your wrapped coil that connects the coil to your build deck. Get it as soon as Fri, Dec 4. The resistance of each individual coil is shown in brackets to the right of the number of wraps. Parallel, twisted, ribbon. $5.29 $ 5. Well because I’m already addicted to the nicotine, so I’m looking for a decent and proper replacement that as close to a cigarette as I can get. If you're making a coil, you'll need to calculate the resistance needed and from that it's a simple matter of calulating the length. The way you wick your coil can also have a massive effect on the end result. A MTL coil is typically around 1ohm. For example: N80, 24ga + 36ga. As long as you’ve selected ‘Round (Parallel 2 Strand)’ our Coil Wrap Calculator will automatically calculate how many times you need to wrap your wire around the coil jig. We also love the Aegis Boost and actually featured it on our Best Pods of 2020 list. For the coil setup you’re using I’d suggest starting off at 10W, especially as you’re vaping with 50mg nicotine salts. What I am trying to figure out – same on/with Steam Engine’s calculator – is how to deal with Clapton Wire in these calculators? What coil wire can I use in Temperature Control (TC) mode? Itching to try a parallel, twisted or even flat ribbon coil? When we do upload a new calculator for more advanced coil builds we’ll separate it from this one. Calculate heating element size Thread starter perky416; Start date Nov 27, 2011; Nov 27, 2011 #1 perky416. thx. Really glad you like the calculator . Please get back in touch and let us know how you get on. Also are your 0.5ohm ECL coils direct-to-lung (DTL) or mouth-to-lung (MTL)? Just dry burn the coil and gently ‘rake’ a mini screwdriver or coil jig over the coil while it’s glowing. Thanks for the great feedback!! Obviously the higher the wattage you vape at, the higher the draw on your battery will be. Ready-made metallic heating elements made from wire or strip in Kanthal iron-chromium-aluminium alloys or Nikrothal nickel-chromium alloys for element temperatures between 50 - 1200°C Element types. I’m a bit dumb, when I look at the results after calculating its specifies 158.30 wraps, I know they don’t mean 158 times to wrap.
