Trouble with kanger coils

[postembr2]

Hi, living in brazil is a pain, i ordered 10 boxes of 5 pieces of kanger coils from fasttech, today i received the bad news, health agency stepped in and probably will destroy it or return to sender. Most probably because i put on the order 1 "electronic cigarette" charger.. damn..
Anyway, being short of local retailers for authentic kanger coils, its often very hard to get much decent supply. Im bracing to start rebuilding its what will do, but also, i tried to dry burn some times, almost always with bad consequences.

Every time i try to dry burn after a water cleansing, the coils get clean and such, nice and clean. The problem is that shortly after, i notice a burn taste that doesnt go off. The taste is the same of the taste of the gunk ash, but the coil looks clean, after several rinses. I come to think the problem maybe the lower insulator is being burn somehow, just dont know how. I seen several videos on people dry burning coils with nothing of this trouble, can someone help me?

The coils are nominal 1.8 ohms. I clean with water, then i try to try burn, using between 3.4-3.6 volts. Until there is water it looks ok, short after it start burning the gunk, and after it starts to smell bad.

If you have a bottom coil tank you shouldn't dry burn it. You prob did burn the insulator

Are you removing the wicks? If you are not, you may be burning them?

I would suggest not "over-burning" the coil. Too much will burn the insulator hence the burn taste.

No im dry burning with the wick, as it get clean too. Problem probably is the insulator, because silica wick will not burn at such temperature. The thing is that i see people on vids dry burning and not getting the same issues.

Lots of ppl on videos claim (and do it) without the problems with after bad taste. I managed to do it once, i just dont recall completely the steps to understand what worked or not. This one i sucessfully dry burned, is almost 2 months in use, rewicked with cotton, no problems.

I dry burn with no issues, not sure why your having problems. My issue with them is keeping them from leaking. So much juice wasted fiddling with them. Would be nice if they worked right out of the package.

I was having burnt taste as well after getting a pack of 2.5 wicks for my PT2. I think I solved my problem the easiest way though. Try flipping the insulator over and putting it back over the wicks. Instead of the cup side down as they are sent, flip it so the cup side is up toward the mouth piece. I have done this on all the replacement Kanger wicks I got from a local B&M store because the insulator was actually covering up the wicks and not allowing any of my juice (even thin juice) from hitting the wick and coil. By flipping the little cap over, it allows the juice to get to the wicks. I was worried about leaking after I first did it, but now 3 wicks into this current pack and flipping all the insulator caps over, I am loving my PT2 once again and getting great flavor, hits and no leaks.

Sounds like you definitely need to start rebuilding. I rebuilt my Kanger heads for a while before moving on to other RBAs. Grimmgreen has a good video on rebuilding protank heads that is worth watching. He uses kanthal wire and silica.

I would seriously consider learning to rebuild them. They are very easy to do and you won't have to worry about finding a place to get replacements. Get some 30g kanthal and some organic cotton balls and you are set. There are multiple youtube videos showing how to rebuild them.

Much less stressful and the vapor and flavor is a huge step up

I have never burned my insulator dry burning kanger coils. The only thing I have done is toasted my wicks. If you remove them and follow the video link I posted, rinse the ash off after the burn - you should not have any lingering burnt taste beyond maybe the first puff or 2 if there is a little ash lingering.

You should remove the wicks, pulse for about 3 seconds at a time and only go until the coil just starts to glow red.

I have almost 0 leaks, only on old coils.

Good call creepy lady! I gonna try this next time when one of my coils has ended its "natural life". It was one of the think i through, but since i read silica is stable up to 1700 C, i wasnt minding of it.

EDIT
When you say "remove the wicks" you are saying all the wicks not just the flavor wicks right?

Actually im just planning on doing it, problem is, i couldnt find local retails selling Kanthal A1, they are just selling Kanthal D with this gauge. From what i seen, the alloy is almost the same, but Kanthal D have 1% less Al. It have almost same resistance properties, but im somewhat worried about safety.

My luck I guess.

The video link in my first post shows you *exactly* how to deal with the wicks

On the vid he just remove the top flavor wicks. So nothing new from what i have being doing. Since im using a "low resistance" coil i will try with reduced voltage, like 3v
