NI200 wire and coil crud.

[Robert Cromwell]

Does the NI200 wire used in temp control mode not crud up as fast? Not at all? Or does it depend on the temp you vape at?

Just curious as I see myself maybe headed in that direction in the future.

My thought is that since the wire runs cooler that it will not crud up as fast or not at all maybe?

I have noticed that my coils get buildup just as quickly as kanthal. Since dry burning nickel makes it very flimsy and almost impossible to rewick, I usually just build another coil almost every day. How quickly the coil gets nasty is going to depend on the juice. I usually use tobacco flavors.

I use 28g ni200 and a 70vg/30pg juice (majority of my juices are this blend) and my coils last several days in my Subtank Mini. I go through 5-8ml a day as well.

true coil killers like NET juices wont really do much better on nickel than kanthal as far as buildup, but IMO temp control deals with buildup better, going longer before you get a bad flavor cast. you can tell when the buildup happens because the temperature needs to be turned up.

but juices that were building up due to coil heat will not generate crud and last far longer. I want to say this includes juices with sweeteners but i have not empirically tested that.

I've been cleaning my coils lightly with water and a toothbrush. But I use tempered nickel which is sturdier. Still...you'll end up replacing them way sooner than with kanthal coils.

 

[Robert Cromwell]

So No dramatic difference then from Kanthal as far as buildup on nickel coils it sounds like.

Thanks for all the replies.

I clean my Kanthal coils by soaking in alcohol and the brushing very lightly with a small natural bristle artists brush with the bristles trimmed short.
Then rinse in hot water 130 deg or so hot.

My experience is the opposite of Pocha, I find coils last longer on the whole. Extremely long, even.

Building coils everyday? That would drive me crazy. I rewick just about everyday, but coils last me weeks....kanthal coils that is...dry burn and your good to go.

Anywhere in the U.S.A.to get the harder tempered nickel wire?

 

[Sptz]

So, if the nickel wire is hard tempered will it be possible to clean them? Re-coiling everyday or every 2 days seems like a nightmare to me : (

I recoil very infrequently

In a little over a month, I have found that coil life for the OCC & RBA sections of the Subtank Mini is approximately two weeks.

However, this is highly variable from juice to juice.

That said, I did not achieve anywhere close to that coil life with Kanthal... I was lucky to get even a week out of Kanthal and some people get over a month...

I re-coil Kanthal almost daily too. . But I usually vape north of 20ml a day.

But dry burning a nickel coil, just slightly pulsing it, MAY or MAY NOT release something right? I'm no expert, didn't do much research, just going by what I read about.

This would be my expectation. With a controlled lower temperature less crud should bake on the coil. Maybe the ones with the crud issues are vaping at 600 degrees?

I have researched this quite a bit and I do not think there are any health risks.
Ni200 will release a wee bit of carbon when heated, Ni200 can contain only 0.15% carbon as the maximum amount allowed.
The carbon lose is a concern when the Ni is structural, it causes a loss of ductility that could lead to parts failure.
It is rated by ANSI for service up to 600 F for pressure vessels and boilers. (because of material strength related to carbon leaching)

I am not a Doctor or an expert in metals.
I am a carbon based life form so I don't worry.
I can dry burn about 8 times before I feel the coil is worn out.
