Should my coils be red?

[trainey]

Hello guys,
Just getting into coil building. I have a sentinel mod with a nimbus. I bought some 30 ga kanthal today and I'm using cotton wicking. I built a dual coil setup with 9 wraps, it read at .9 ohms. When I use it, it fires and vapes decently but I was just wondering why my coils aren't glowing red. I'm not sure if they're supposed to or not I just know the coils that came with the nimbus did. Just want to make sure I'm doing everything right and safe. I've watched a ton of videos and read articles on coil building but I could not find anything that mentions this specifically. Thanks guys.

When fired dry (Which you should not do with cotton) your coil should glow, but they should not glow when wet. If they do.... You'll have an extremely bad vape

they wont turn red when the cotton is juiced up....pull the cotton out and dry fire it and they will glow

Ah okay so I guess I'm good then. The vape is very clean, no burnt taste at all. This is my first rebuildable and I just remember seeing the coils that came in it glowing red even when I did have juice on it so thought I was doing something wrong. Thnx guys!

I lower the watts on my mod to 3 to do dry burning; they just glow red and no risk of frying them.

If you are rebuilding though on a rebuildable, you can just recoil!

As others have stated, it will only glow red when the wick is taken out and you dry burn the coils. With wick the coils are transferring heat and spreading the heat into the material so you will not see a glowing red.

Thanks for all the responses. Feeling pretty good about my first coils now!

If the coil is glowing red when you have it wicked and juiced you have a problem. Usually it is a issue with your wick (too much will choke it up and prevent juice from properly flowing to the coil, too little will have a gap between the wick and coil in spots, causing that part of the coil to get too hot). It also can be caused by sloppy coil wrapping, again causing a gap between the wick and coil in spots.

You want to avoid this, especially if you are using cotton wicks. If you have a hotspot with a cotton wick it will burn almost instantaneously. Silica is more forgiving since it won't actually burn when dry, but you will get a really nasty hit and may scorch the wick.
