Great choice of coil build, I love the parallel coil build myself! This is never more important than when using an unregulated mod (Mechanical), a direct short to ground/earth could be dangerous. The wrap gauge is pretty insignificant compared to the core gauge and only changes the number of wraps required by a very fractional amount. If your coil is 1.6ohms though I’d expect a fair amount of vapor anywhere above 15W. Above all, it’s best to just use whatever you find works best for you. Equation No. However I shall continue to build 3mm coils as the extra wick holding more juice seems to last longer. 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. If you’d like to share this calculator then please hit one of the share buttons below. could you shed the light on how to count wraps? 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. Just be careful not to go too high! 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. Anything on that scale should give you great flavor and vapor! When I’m making a parallel coil, is the number of wraps the number of times I wrap the coil jig? AWG is printed on all spools of wire. This What I am trying to figure out – same on/with Steam Engine’s calculator – is how to deal with Clapton Wire in these calculators? If you’ve not already done so then take a look at our calculator guide and coil building guide. When I put it in my mod it will not vape at any wattage. Thanks again and great work! 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 … For example: N80, 24ga + 36ga. Hope this helps, not trying to hijack this so first off thanks. Please let us know what you find the best wattage to be though. I tried to recoil using kanthal A1 32 awg. Any problems, feel free to drop me a reply! Thanks for the calculators, they work fine. Needle nose pliers (or tweezers in a pinch) are also important to shape your coil after you’ve installed it. If so six wraps of this should give you approx 0.7ohms. A half wrap refers to the coil legs pointing in the same direction. Why? Get it as soon as Fri, Dec 4. If we’re feeling in the mood, we usually wrap a few coils in one sitting so we’ve got a couple to hand. When we do upload a new calculator for more advanced coil builds we’ll separate it from this one. Heaters can be coiled to lengths greater than shown with or without wattage profiling. 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. 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. Thanks. I’ll definitely install it. Ultimately though you can experiment with the wattage you’re using on a regulated mod and see what works best for you. 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’s important you stick within the safe range your device can handle! i.e. We’ve got a section in our coil building guide that covers potential problems with a coil. If your using 20A batteries, you cannot vape any higher than 110W before you’re in danger of overloading your batteries (see our Battery Amp Drain Calculator). It could also be worth experimenting with your wicking method as well. Thanks for your comment and I hope the following helps. 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? The table shows the standard lengths and wattages that are available off the shelf for coiling and immediate delivery. E.g. and a pair of cutters. 5.0 out of 5 stars 8. What's the difference between a half wrap and full wrap? Thanks for the message. One day a friend gave me an MTL device and the smoking just stopped. thanks for providing the calculator , they work fine. Also on a regulated mod remember the coil resistance doesn’t determine the current drain, it’s the wattage and voltage. uxcell Heating Element Coil Wire AC220V 3000W / AC110V 750W Kiln Furnace Heater Wire 7.2mmx800mm 3PCS. It needs heating of 50 to 65 deg. However, this is always dependent on the mod and/or tank you’re using. Use an Ohm reader to make sure that the resistance is roughly where you want it. Hi, very grateful with your calculator here. as the cube is variable wattage can I safely use on the 1-80w range? However, I saw on a YouTube video about building, that we should aim for 8-10wraps, no more. 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. Am I safe? I felt all the burnt stuff and yeah, just realized that smoking is a horrible mistake. The outer wrap of a Clapton is fairly insignificant with respect to the core wrap in terms of resistance. 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. If you’re heating the coil at 5W then you probably won’t produce much vapor. A half wrap refers to the coil legs pointing in the same direction whereas a full wrap means the coil legs point in opposite directions. This will be fine as long as you don’t vape higher than 110W using your 20A batteries. Your vaping power at this build will be approx. My best advice would be to try it and see if you find any noticeable difference. witch could become expensive. There’s no reason you can’t build with more coil wraps than this, however more wraps doesn’t necessarily guarantee better flavour. The tail lead length is the total length of the two ends. I wanna use abit less juice as I am averaging 100ML in 2 days ooF. sometimes i got the same resistance with bit different wraps 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. Be sure to have a read through our wicking guide too. It can’t be included in your calculator right . 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. The way you wick your coil can also have a massive effect on the end result. 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. Heating Coil - Water Outputs. is there any advantage / disadvantage (Flavour etc) building a coil with 3mm diameter and 1 less wrap again aiming for about 1.2 ohm ? Many thanks again. This will give you a 1.4ohm vape coil which I think should roughly mimic the vape experience on a Vape Pod device. We’d really appreciate it if you share the page with friends and family too! Use this calculator to estimate the cooling needs of a typical room or house, such as finding out the power of a window air conditioner needed for an apartment room or the central air conditioner for an entire house. Hope this helps Ronald, any problems feel free to let us know. Thank you very much! 16 0. The thinner wire wrapping around the core wires only changes the number of wraps needed by a fractional amount. The size of whatever you use dictates the inner coil diameter. I used your calculator (btw, it’s soo cool!) Instead, the wattage you choose to vape affects how much power you draw from your battery. I’m going for a 0.3 ohm coil using 28G Kanthal A1. However, it’s really only useful when you’re using an unregulated mod (mechanical) on a fully charged battery (4.2V). 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. 1) Using twisted kanthal on a dual build deck to achieve an overall deck resistance of 0.4 or 0.5ohm will mean too many wraps for your build deck. Thanks for the comment. We’d usually suggest sticking to around 6 wraps as this will give you a good cross sectional surface area with decent flavor. Target resistance is the resistance you want your coil/deck to be. There isn’t a battery on the market capable of supplying that amount of current at present. The airflow can sometimes be restricted by wick sitting over the air holes. You’ll be pleased to hear we’ll be including flat ribbon wire in a future update to the coil wrap calculator , Very Nice, just did 3 builds and your calcs are right on the money. If i used 30 awg instead, is it gonna give more flavor and vapor؟. Keep trying though as you will get there. thx. Thanks for your comment. 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. The ‘4.2v’ refers to the voltage of a fully charged 18650 vape battery; as you use the battery the voltage (capacity) drops until you need to charge it again. Hello 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. 2) Alternatively, if you’re using a regulated mod the resistance of your coil doesn’t affect the drain on your battery. In this case you can use our ‘Battery Amp Draw Calculator‘ to check the current drain on your battery when using a regulated mod. For specific heating element or resistor design please consult a qualified electrical design engineer. Did you dry burn your coil to make sure there were no hotspots? The resistance is determined by the number of wraps, the diameter of the wire and circumference of the wrap. Because I don’t wanna go that road again. The surface area of both coils will be approx. We really recommend this one here from Amazon, it’s a great kit at a really decent price. Please guide. The total wattage is calculated using the amount of airflow (SCFM) and the temperature rise (∆T) desired. If you’ve had any problems with the Coil Wrap Calculator, please see the user guide here. Russell. We’re also going to be posting a review of the Aegis Boost and RBA soon. Thanks for the comment! A full wrap refers to the coil legs pointing in opposite directions. Part 1 Calculate the average steam mass flowrate during start-up. For infinite resistance, i.e. What coil wire can I use in Variable Wattage mode? A = area; Q = total heat input required; U = number describing the heat transfer coefficient or degree of influence of materials, agitation, viscosity and other system details. 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! Resistive heat losses due to voltage drops are exactly what I'm after. This can really affect the vapor produced. i’m using ni80 24 awg Yes, our calculator will work out the required wraps for any type of wire. You’re drawing 38Amps from a Samsung 25R 18650 battery which is rated at 25Amps. Finally, you might also need a metre to test your Ohms, although most mods will tell you the coil resistance. Thanks for great feedback and glad you like the calculator. How many wraps? Four turns of Kanthal A1 will produce a 1.2 ohm coil using 30AWG wire. To wrap a coil, you’ll need either a drill bit, a screwdriver or (ideally!) By inputting just the core wire profile and AWG you’ll be getting a roughly similar result. Hi Tony, glad you found the calculator helpful! 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’. I recently purchased Geekvape Twisted 26AWGx2 Kanthal A1 wire to experiment my builds with. Your coil build (deck resistance) at 0.11ohms is too low. Thanks for the question. I’m currently designing a separate calculator specifically for clapton, fused clapton and alien coils. 5% coupon applied at checkout Save 5% with coupon. To give you a very close result you can just select ‘dual strand’ and input the 28 AWG inner core wires. Thanks for the comment and really happy to hear you like the calculator! 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. Standard Coil Sizes. Your email address will not be published. Just dry burn the coil and gently ‘rake’ a mini screwdriver or coil jig over the coil while it’s glowing. I use a coil cutting tool and cut each leg to +/- 4.5-5mm. Another question is regarding the wraps. You need to increase the coil resistance to 0.18ohms or higher so not to draw above 25Amps from the battery. Hi sir, im using minifit. What does 'Current Drain from Battery' mean? , is there a chance you can add flat wire…would like to do some twisted flat wire coils..and this calc is very easy to use, Hi Alan, thanks for the feedback! The resistance of each individual coil is shown in brackets to the right of the number of wraps. FREE Shipping on orders over $25 shipped by Amazon. 160Watts. 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? Hi Nichole, thanks for the comment You don’t need to half the number of wraps. Hope that helps. 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. Overview – Heating Element Design and Calculation. and it showed that i should make a 19/18 rounded half wrap? Ideally you want around 6 wraps per coil to be able to fit in between the deck posts. We continually train our team and develop new machinery to … 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) cheers bud, No worries. Hope this helps Max. (W=SCFM∙∆T /3) The wattage of each coil is the total wattage divided by the number of coils in the circuit. Vaping in the region of 15W – 50W shouldn’t be an issue…your face should be fine . Have a question hoping you can answer. I think you’re getting slightly confused here between voltage and wattage. 89. Teach Me - Heating Coil Pipe Sizing - posted in Student: Anybody to help will be excellent. It’s telling me I need 1 and a bit wraps, surely that can’t be right.
