Burnt taste

[saeybia]

Hi the other day I had my first taste of burnt liquid OMG that was disgusting!

Anyway I washed the tank and changed the coil.

I still had a slight burnt taste but that went. Anyway used the same liquid and it's starting to get that burnt taste again. I only have the wattage set at 30 so have no idea what's going on.

Just washed out and changed to a TC coil this time to see if that helps but am I doing something wrong?

What is your VG/PG ratio of your juice and what tank are you using?

Hi its 70vg 30pg I give it extra time to soak up the liquid as it is quite thick. I'm also using a Melo 3 tank

Things that make coils gunk up to give a bad burnt taste

1) Liquid Viscosity, higher the VG content the higher the viscosity, can equate to slower wicking with factory coils, especially during winter, VG is also sometimes a sweetener so can collect up as goo in a coil or crystalize in the wicking, or carbon on the wire
2) Sweeteners of any sort, very very very sweet liquids will will create goo, crystalize in the wicking or collect as carbon on the wire
3) Dark Liquids, darker the liquid the more it is going to carbonize and crystalize in the coil head like sweeteners above, coffees, tobaccos, caramels are very notorious here
4) Creamy flavors, if it has cream, milky, yogurts, rich buttery toned liquids, like sweeteners, builds up gunk
5) Bakery and savory flavors, things like cheesecakes, donuts, bear claws, cakes, cookies are majorly compounded by #1-4
6) Heat - this boils down to burning out your wicking, to hot and the liquid isn't flowing fast enough or the air flow is not adequate enough for your wattage you gradually scorch your wicking which is most times make of cotton which has a very low scorching temperature.

Well sweet blackberry lemonade High vg lol guess that's it time to go back to a menthol I think

Hmmm... That should wick ok. Not sure what the issue might be. I see there is a "check list" above my post so hopefully that helps.

 

[saeybia]

Well I've dumped it all out again. If it doesn't work I will get some lower VG liquid

Melo 3 tank, but what coil(s) are you trying this with (and yes, a dry hit is really miserable)?

 

[saeybia]

First happened on a 0.3 ohm coil. Second was on a 0.5ohm. Just switched to a 0.5 titanium.

The burnt ones were kanthal.

Don't know. Those Kanthal coils should have been OK if you primed them properly then worked the wattage up slowly. Make sure you prime the Ti coil well also. You are priming them, right?

 

[saeybia]

Leaving it in for 20 minutes without using it then taking pulls without switching the mod on. How slowly should I be working the wattage up?

For a factory coil, I would place several drops of juice in it and on the little holes on the side, then let it sit for 10 minutes or so in a full tank. I would then take a few draws without power (I also do one or two draws with the air flow closed to and assure some vacuum). Then I start out about half the power where I expect to end up and work my way up a few watts at a time. In a subohm setting, I'd probably go a bit faster than my 1 to 2 watt creep up for mtl, maybe 3 to 4W jumps. So if your "goal" for a 0.5 ohm coil is going to be 30W, start at 15W and go up a few W at a time. In a smaller tank, it might take a tankful or 2 ml to "break" the coil completely in.

Note, the final power setting/wattage will depend completely on when you feel you've hit your "sweet spot" in performance. For any coil it could be 15W, 20W, or 40W. Depends on your preference (and not burning or flooding the coil) Do not rely on the power settings printed on the coil as a target. They are at best a general suggestion, and are usually inflated anyway. Just because it says 30-50W doesn't mean you should use it only in that range.

Oh that's amazing instructions. I have found that I like the wattage around 25-30 and temp around 200c so will drop the wattage some and work it up

Thank you

I've never had a tank give off dry hits because of high VG. I've been doing high VG juice since soon after I started vaping as I like the smoothness of it. I suppose if you were doing some hard chain vaping it could be an issue. The Melo III can handle high VG no problem especially with those subohm coils. Something else is obviously the culprit.

Also just noticed you mentioned temperature. The standard coils do not do TC which I think you are already aware of.

 

[saeybia]

Yeah the standard coils I was using in wattage Mode at 30watts. Got some TC coils now and gonna try them out to see if it doesn't burn. Maybe just a dodgy batch of coils?

Not clear to me, but if you started those Kanthal coils straight out at 30W, even with letting them soak, you probably "overpowered" them. Factory coils can be very picky about that stuff, whereas DIY coils and wicks are usually well saturated and tested during the build process, so it's less of a problem.

 

[saeybia]

OK. I did start them at 30w I will keep the wattage low and work it up. Still learning here lol.

Yeah, my money would be on that as the problem. Factory coils really need a chance to break in, and starting at 30W as probably the issue. Good luck!

I think the most important thing is putting a few drops on all the open spots where cotton is exposed before installing the coil. Now mind you Ive never used a melo 3, but all I ever do is manually put drops on all the exposed parts of the Cotton then take a couple of non-powered pulls before I start vaping. I hardly ever let the tank sit and I never start with low power. Never had an issue with any of my tanks (all sub-ohm).
