Resistance too low (Ni200), possible remedy?

[BillW50]

After you wicked it with cotton or whatever you use, you can recheck to see if the resistance had dropped. If it did, that means a wrap or more may have shorted. Repeat the advice from the previous post. Either soaked in juice or not. If not, keep the temperature low to avoid burning the dry wicking.

Thank you, now I know what you mean. And now I remember having a pair of teflon tweezers, I had forgotten about them...But here's what I don't understand: You said to do this procedure (getting rid of the shorts) in the context of contact coils, and that doesn't make sense to me. I thought that in a contact coil, the wires are supposed to be in contact with each other, so what shorts should I get rid of?

Sure no problem. You run something non conductive and can handle heat like Teflon tweezers across the coil while firing. Or use metal tweezers or a screwdriver or something while not firing. The resistance will increase as the shorts will disappear.

Physical contact is one thing, electrical contact is another. Contact coils are physically connected. But they shouldn't be electrically connected. As you don't want shorts. As you will have hot spots and it will vape horribly. You're much better off using spaced coils to avoid all of this. But if you insist, you must remove the shorts.

Contact coils are a bad idea if you use Ni200. The necessity to dry burn them to make them glow evenly causes more problems than it has advantages.
Just build spaced coils.

Thanks, now I get it

I've been reading a little bit about spaced coils vs contact coils, and I came to the same conclusion (that it's better to make spaced coils). I will still be able to use my Ni200 30 Ga spool (which might be 28Ga in actuality), but not the thicker ones (24 and 26 Ga).

Thanks everyone
