Thanks for the fantastic feedback! OEM replacement coil heating elements, known as coil heaters. 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. My best advice would be to try it and see if you find any noticeable difference. However, I saw on a YouTube video about building, that we should aim for 8-10wraps, no more. 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. Stainless Steel (316) can be used in either Temperature Control or Variable Wattage mode. This obviously won’t give you a coil with much surface area, which will impact flavor and vapor production… Our advice would be to perhaps switch to 30AWG in which case you’d need 6 full wraps to hit 1.4ohms. Coil Building Tips & Tricks – How to Build a Vape Coil in 6 Easy Steps! 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.

The tiger coil is a twisted ribbon wire with a single round wire and to make it more complicated there are two different types of wire being used. 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’. The outer wrap of a Clapton is fairly insignificant with respect to the core wrap in terms of resistance. Hi there, thank you so much for a great calculator. Read this helpful blog post or check out our coil design PDF to learn more. Great job. 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. Nicotine Shot Calculator / Shortfill Calculator. For infinite resistance, i.e. The vertical coil can be wicked on either the inside or outside, which is more commonly known as a ‘chimney’ coil. AWG stands for American Wire Gauge. Personally, we prefer this method as we notice less ‘spitback’ from these when compared with vertical coils. For specific heating element or resistor design please consult a qualified electrical design engineer. Many thanks again. The difference between full and half wraps depends on the way the coil(s) are fitted into the build deck. What coil wire can I use in Variable Wattage mode? If we’re feeling in the mood, we usually wrap a few coils in one sitting so we’ve got a couple to hand. However, this won’t necessarily fix the problem you’ve described. I managed to make one of about 6 wraps and got 1.6ohms on my ohms reader. I used a 7/6 wraps (per coil, btw it’s a dual coil deck).
