Nichrome coil meltdown

[krashman71]

I did a dual coil build with 22 gauge nichrome 5/6 wrap. Checked with ohm meter (0.15). When I fired it up to adjust the coils, the coils deformed and melted off of the posts onto the deck. What did I do wrong?

I'm thinking that You fired it for too long. And too long can be just a matter of a second or two with a coil that hot.
I've done the same thing but with 30g twisted kanthal. Fired it for about 2 seconds maybe and, bloop, melted right off the posts. It was a good learning experience for me.

I have never heard of that happening.

What kind of device was delivering the power to the coils?

 

[Hobby Kid]

I think nichrome heats up faster. Or at least the same wraps compared to kanthal will give a lower ohm. I only use kanthal. I used to use nichrome and it's the only time coils have ever popped on me.

It's the nichrome. I pulse kanthal a lot when adjusting new coils and cleaning old ones. The nichrome won't take half of what kanthal can take before turning to slag.

 

[krashman71]

This was my first experience with nichrome. I guess I'll try again and not be so heavy on the switch. Thanks.

 

[Hobby Kid]

Is there a particular reason you're using nichrome krashman?

 

[krashman71]

I screwed up when I ordered. Just wanted 22g and didn't realize it was nichrome. Won't happen again.

 

[krashman71]

Will kanthal hold up better to longer hits?

Just using a TurtleShip Mech with a sony 18650.

 

[UncleRJ]

Yup,

The Nichrome just was not up to the task or the power of your Sony powered mech.

It's very thick though isn't it, 22g ? It must've been very hot! What about trying twisting a couple of strands? See how that goes

Twisting the 22G or smaller wire?

Twisting a couple of strands of the 22g together

 

[krashman71]

What will that do?

 

[Hobby Kid]

I'm figuring with more wraps and a thicker wire it'll be harder to melt. Tbh idk. It was just a thought

 

[krashman71]

I thought it would create a lower resistance resulting in even more heat.

That is right. Two 28 wrapped would be a thick ass coil imo. If it was me I would just stick with a single strand and bring your ohms up a bit.

 

[Hobby Kid]

Well if you do as many wraps as you did, it would theoretically halve them. So you would do more wraps to up the ohms

 

[Fishee]

But if the original build is what you're wanting then stick with what you did. Just don't fire it for so long. You don't have to make the coils glow you just have to make them hot in order to manipulate them.

 

[krashman71]

Ok. I'll experiment tonight and see what happens. I will post my results.

 

[krashman71]

Thanks guys.

Yes please do. I'd like to know what you end up doing or what works. When I began vaping a couple of yrs ago the vendor I regularly used only sold nichrome and I didn't know any better and had a lot of issues with it. Was very springy stuff too. Then about two months ago I unintentionally made a coil with it in a kayfun mini.. and it popped after a day. And that wasn't even a sub ohm. (actually what happened was I accidentally dribbled down the driptip as I do sometimes lol and it killed the coil)

22gauge 7-8 wraps @30 Watts is prime I just used a medium size screwdriver to wrap and single coil 1.5ohms great flavor and cool vape, careful at 40-50 watts if burning off juice it will ignite had to blow out the wick

I've never had that happen or heard of it until running across this forum. Very interesting. I'm stuck on single 18650 devices however. The "not so trusty" Nemesis (now I understand why the name. Spot on! Lol), an eleaf 40watt TC & ever trusty (& I mean it...) ipv d2. Had my beautiful blue shiny YiHi SX Mini ML C Class taken with a brand new Royal Hunter after getting the RDA the day before. Anyway, sticking to topic, I think I'll give it a shot. Melting a coils legs off. Ha, sounds interesting! Anyone know anyway I can build a dual coil setup, any size, any # out coils, diameter, etc. out of .22 gauge nichrome? I bought 100ft. roll before I even knew the gauge rules or much about dripping. I believe I'd started buying 100ft in every gauge & only had an igo-w by UD. Obviously I'm stuck in old school mode, although that's GREATLY evolved! Anything with the nichrome? Maybe use on temp control mode on the ipv d2? Help a chick out. ;-)
