IGO W6 Issue

Status
Not open for further replies.
I recently got the IGO W6, and built it with a quad 24 gauge kanthal coil build, at .2 ohms. I followed rip trippers video and mimicked it exactly. It was fantastic, it was warm, big clouds, great vapor. I have it on a Copper Nemesis style mechanical mod clone. I also have it with a Sony Vtc4 to power it. It was great for a few days, I do not think this has anything to do with it, but I will include it because it happened in close time proximity to the issue, a ordered and installed, .925 silver coated contact pins, BOY it hit like a train after that. Some time after one of my vapes turned out horrific. The smoke didnt even taste like anything, it burned the inside of my mouth, not from heat, but harshness of vapor. Left a terrible taste. I removed the cotton, cleaned the coils, reinstalled them, threaded fresh cotton, and it was fine for 2 or 3 vapes. Then it did it again, when a friend of mine was watching. According to him, he could see a coil through one of the airholes. It lit up bright orange when we took of the cap, and fired to watch. It was normal. Cant tell the issue. it only does it sometime, I retired my w6 until i figure it out. Im scared to try to rebuild new coils, or whatever and vape on it again until i know for sure. (its that bad) I couldnt find any shorts. My other dripper, the magma paradigm, fires without error. The strangest thing atleast to me, is that coils dont (Normally) get orange when they have cotton, and juice running through them, all heat is diffused to the vaporization. Only when you dry fire them after installing (to detect even redness and resistance) do they get that hot. So what could of cause them to so hot that they turned red even under load. I cannot recall for sure, this is a maybe, ( as i was overtaken by the horrible burning) there may have been a subtle pop when it happened. I have searched everywhere and found nothing. Any thoughts?

Did you take the dripper off and put it on an ohm meter to make sure you don't have a short? Also if you put new pins in the mod, make sure the center pin is only touching the post of the atomizer and not shorting out. Make sure you don't have any hot spots in the coils that would cause a portion of the cotton to go dry quicker then the rest, which would cause a dry hit and explain the taste you were getting.

That's the problem, you have a hot spot for some reason that is burning juice. That's not safe to vape so it's good you retired it until you figure it out :thumb:

You didn't say if you're using micro coils that touch each other (contact coils). If you are, take out the wicks and fire the coils. The coils should be heating up from the center out and the tails going to the posts should not glow. If this is not happening, heat the coils til they glow, let go of the button and compress the problem coil with tweezers until it cools a bit. It should now be good and hopefully your problem is solved.

If your not using contact coils make sure your last wire wrap does not drift away from the wick slowly, but does so abruptly. This is kind of hard to explain and I don't have a picture to help me with it, so I hope this makes some kind of sense.

The last thing is make sure no part of your coils could be intermittently shorting on the deck. It's not the cap because it did this without the cap on.

ETA: It would be nice if you used a couple of paragraph breaks in your post to make it easier to read :)

I appreciate your response, and I was in a rush when I typed it, but I will use breaks.

I did take out the cotton before and fire it, no hot spots, and I did use an ohm meter. All clear. The weird part is the fact that you would think that if I took out the cotton, and dryfired it, you would see one coil clearly hotter. But they fire evenly (so evenly Im proud of it and my work I put into it.) It only happens occasionally. Thats why its scary, like a landmine. Top notch vape experience THEN BAM, Satan farts in my mouth.

So what causes it to sometimes weird out? Ill post pics, it looks normal. Also, I am using contact coils.

You're welcome :)

I've never tried vertical coils, so take this with a grain of salt. I've also only done dual coils max, so I have no experience with more coils than that.

IMO, one issue could be the long legs you're using in close proximity to cotton, specially the one I marked 'B'. IMO 'A' is shorter and will not be a factor.

Here is how I set up my Trident with dual micro coils at 0.5 ohms (yes, the coils are way gunked up ;)):

I've never got any burnt hits from this setup unless I let the cotton get too dry. The coil legs leave the main coil abruptly and there is no cotton nearby to get them slightly wet. I'm thinking if you have some contact of cotton to your coil tails, that might allow them to get wet enough to fry juice sometimes.

As you can see, I'm also using a lot less cotton than you are.

Again, this is just my opinion. I'm reaching here because this has never happened to me.

Hope this may help a bit and let us know how it turns out for you :thumb:

The clue here is his friend saw red glowing through the side which is a clear indicator that there's a hot spot.

When you test your build without the cap on, cotton in place and juice on the cotton, are you allowing it to fire long enough to see the hotspot? It honestly sounds exactly like a hot spot (probably on wire coming from the actual coil).

Is there anyway you can snap a pic of your build firing without the cap on?
