At Which resistance should coils be changed?

[ArcAngel1982]

hi all,

Really glad to see the wealth of knowledge on this forum. Super helpful for noobs like me.

Im sorry if this is a ridiculous question, but I've searched for a couple of days yet can't seem to find an answer for this.

I've just started vaping with an istick Pico with a melo 3 mini tank with a 0.3. Ohm coil. I love it, but have a question I'm paranoid about - at which coild resitance do I need to change the coil? The mod display read 0.26 when I first started using it, but then dropped to 0.25, and is now @ 0.23. My question - when should I change it? So frt no burnt taste nor drop in vapour. I'm just worried that the coil would start producing toxic fumes or something. Please help. Thanks in advance.

Change your coils when they start tasting burnt.. Resistance can change for all sorts of reasons but as long as it still tastes good you're good

Thanks. I was a bit paranoid cos I read that burnt coils can produce toxic fumes, so wanted to be sure I wasn't pushing my luck.

I don't know (much) about toxic fumes, that is more to do with coils glowing away with no juice on them or totally overpowered due to conscious abuse by anti-e-cigarette scientists.

You/we will know the taste of a coil with a burned 'crust' of gunk as the taste is dreadful.

Fluctuating resistance is normal and can be quite variable. I wouldn't worry about a coil rated at say 0.5 reading a bit either way down to 0.4 or up to 0.6.

Thanks. This is really helpful. So I'm gonna rock this coil till it tastes like dread.

if you can replace the wick, when it starts tasting a bit wrong, remove wic, dry burn the coil, rewick....

and its a matter of taste that determines whats wrong... some people drink dark roast coffie, I think dark roast is more like burnt coffie

Sounds like the resistance meter is off.

As a coil is used The resistance slowly climbs.

Since you are using premade coils most likely. Chsnge the coil when the vapor tastes off.

I use a Kayfun lite plus V2 RTA. I build my coils to .8 ohm resistance. After my resistance climbs to 1 ohm (usually about 3 months (changing wick every few days) i toss the old coil and install another.

Thats not going to happen unless you heated the coiks to 1000 degrees Fahrenheit and above. Then tge vapor woukd be WAY too hot for the mouth and deffinitely too hot for the lungs.


Tge idea about formaldehyde was a scam. These so called scientists heavily modified a mod to put out an excessive amount of heat that NO sane person woukd ever vape that hot.

I like medium roast coffee myself.

Coffee that has been roasted till THR essential oils comes out of the bean and goes rancid us SIMPLY GROSS

Someone can correct me if need be but I use kanthal and never used any of the titanium or nickle to build my coils. If used improperly or without the proper temp control settings nickle and titanium may cause noxious fumes. Since I exclusively use kanthal I've really never paid attention or researched it out properly. I also read that contact coils also can give off fumes from wire touching itself but I have built my share of contact coils and live to tell about it. I personally do prefer spaced coils because the way I see it is your defeating the juice vaporizing procedure by not allowing juice to contact around the entire coil not just the inside middle of the coil. I inhaled many noxious fumes smoking ciggys so whats another fume or two.

You'd have to heat the coil to very high temperatures, and that's most likely impossible with a wet coil. Dry burning is where the potential risk is at.

Seeing as I'm on my first couple of weeks, I'm not sure I'm ready for such a task.

I think I will keep this coil till it's busted, and then take it apart and tinker with it for experience. (is it possible to do this with the Melo iii coils?)

I dont think it is possible to take apart the prefab coils. Unless you are just "taking them apart" to learn how they work, but that involves destroying them....which can also be fun

@Bunnykiller was referring to rewicking on an RBA(rebuildable atomizer).

I just watched a YouTube vid on how to rebuild the MeloIII. Its a vertical coil, well to me doesn't look too hard to rebuild. I wouldn't be throwing those spent heads away, just rinse them out and set aside for that day you do decide too sit down and try to rebuild, find it being way easier than imagined then choked that you threw out all those potential rebuilds.

I hate to ask a dumb question but if you once determine to rebuild a coil why would you need to save more than one (or two if you insist)?

Eventually, the o-rings and seals wear out. If you only saved one, you are back to buying another pack. If you saved them all while buying premade, you have a huge stash for when you choose to rebuild.

Also, having more than one means you can always have a couple ready to go. If you need a new ones, you change in the fly and rebuild at your convenience.

Its more for the parts. That rubber positive insulator can break, burn or simply get old from being reused so many times. Being vertical coils there is really no rewicking them without removing the coil so may as well rebuild it, find horizontal heads or be able to put a horizontal build into the vertical coil head...I dunno. You don't want to remove the wire to change the wicking, its counterproductive. I had many of my protank insulators crisp up just from being well used. Nice to have a couple heads built, ready to juice and go. Backups for your backed up backups is the norm for most of us vapers now since the future of vaping and access of getting gear is in question.
DON'T let rebuilding intimidate you. The day you sit back and take that first hit off a coil that YOU built, your eyes will roll back into your head, you'll be amazed at the night and day difference in vape quality and then you'll start kicking yourself for not starting earlier.

I've been seeing vids on youtube on people washing the prefab coils, then blowing through them while closing the airholes and then reusing them. Has anyone tried this? is this a thing?
