rebuilding Kanger occ coils

[cepak477]

I have rebuilt a coil head with a 4/5 wrap of 24 gauge kanthal, ohming out around .5. I get a burnt taste every once in a while, the first three rebuilds I pulled do to this and noticed that it wasn't the cotton that was burning, the legs of the coil, due to it not being non-resistance wire gets hot and creates a nasty taste. Is there anything I could do differently to avoid this with out using non-resistance wire

Don't you HAVE to use resistant wire? Otherwise your coil is at 0 ohms? How are you getting 0.5 if your wire isn't resistance? I thought all Kanthal was resistance, I thought that was the point of it, no?

Hi cepak and welcome to ECF!

There are only two things you can do. One is to wrap a higher ohm coil so that it doesn't get as hot as quickly and make sure that you are vaping style doesn't let it get as hot. The other is o get some MR-R-NR wire. Fasttech sells them in various resistances.

@Kanger Banger: Welcome aboard as well. cepak was talking about non-resistance-resistance-non-resistance wire. It's where non-resistance wire is welded to the ends of resistance wire and used for the legs of the coil. Since the legs of the coil are then non-resistance, they don't heat up and burn the insulator at the bottom of the coil head.

Hope it helps and Happy vaping!

The 24 gage wire is likely your issue. You're likely burning or at least overheating the rubber insulater at the bottom of the coil. Stick to 26 gage kanthal and keep the resistance at or above 0.4 ohms and all should be good.
