Hey, I've been lurking around here for about 6 months now and vaping about the same. My current set ups are a SID with Vision Xjet BDC, MVP2 with Aspire Nautilus, and a Vision spinner with Xjet. Over the past month or two I've been looking a lot into rebuildables and making my own coils because I seem to run through them. I've recently bought an IGO W3, 28 gauge kanthal, and some cotton. My first question I suppose is that can I use this W3 on a VV/VW device or only a mech mod? Reason I ask is because my first coil I made was 1.6 ohms. I said ok that's good to start. Let me put some juice on it and try this bad boy out. I put it on my SID and set to 12 watts and was noticing the air flow was basically all air as I hit this thing. I know the airflow is adjustable on the W3 but when I say I pulled this thing and got only air I mean like only air. Not much vapor at all. btw, I only made a single coil in the W3. I also tried it on my MVP2 and got the same results. I'm wondering if I'm just not setting the VV/VW high enough to make this thing give me proper vapor. Any help is very appreciated. Thank you.
First, check your contacts. By contact, I mean make sure that your rda is twisted on to your device well and making good contact. Make sure that your screws in the atomizer are nice and snug and making good contact with your wire. If you are good there, dry fire it WITHOUT the cotton (cotton WILL burn) and make sure the coil glows from the inside out. If you can check the boxes on all of the above then you are not using enough wick. Be careful with cotton though. Use too much cotton and you will get a dry/burnt hit because the wick will choke the coil. Also, no, you do not have to have a mech to get good performance from a rebuildable. 1.6 ohms at 12 watts is roughly 4.4 volts which should be more than enough to get some good vapor production. More airflow is good for vapor production on rda's so having it wide open should be giving you more vapor, not less. I hope all this helps and Good luck. Report back later with some pictures and results if you can and I'll do what I can to help.
