I use mostly single wire coils now, but when I was making fancier wires I would never dry burn to clean my coils. I found the flavor to be rather muted after cleaning/dry burning and rewicking the coils with fresh cotton. I thought that maybe it was me or my choice of wicking material, so I tried with Cotton Bacon, Muji pads and a few others, but it was the dry burning that left my juices tasting flat and muted.
Then again, I’ve got weird taste buds so YMMV. That’s my two cents on the issue.
This used to happen to me too but it was chinese wire or coils usually. Some brands are better than others that’s for sure. Since I’ve been making my own coils (or rather since a friend sent me some of his hand made coils), I noticed that the quality was a lot better. I can use coils for months on end now. I try to get the best wire I can and make my coils out of that.
I like to use really fine clapton wraps. Sometimes the little clapton wraps break before I end up changing the coil. I use a magnifying tool to always inspect them before re wicking. I know what you mean though… Some people can detect things others can’t. Some people think all coils taste the same… Strictly mesh coil people like to think it’s superior to wire etc. Everybody’s different and preferences are all over the place.
all wire regardless of make should not be glowed anyways, it releases compound in the metal… These are not the conditions you’d be vaping in so there for it is not required, use a brush or change them all together. You can achieve an evenly burning coil by wrapping it spaced and heating it slightly, inserting a rod and squeezing the spaced coil together with your tweezers and you’ll have for the most part an even heating coil. There will be hot spots in fancier coils, but for claptons and fused it’ll be fine if you did it right. As far as fancier coils, they are just for show and instagram pictures. Vaping a gargoyle hoof triple sow cow 360 nerf herder isn’t going to make it taste better. So keep it simple.
I disagree. I do agree that there’s lots of coils that I just consider showboat coils. Some of them definitely give me better flavor than others. They don’t seem to help as much for low wattage vaping because not much metal mass is needed. From mid to high range (I know everybody defines this differently), the right coil can make all the difference in the world.
Last week I saw pictures of an interlock alien build. I’ve never made them so I spent a few days making them and getting used to it. I should’ve tried the coils sooner because it was a waste of time. Regular alien coils vape better than those interlocking ones.
I also disagree. First it depends on how you’re defining “glowed” and the wire type. T1 should definitely be approached with caution when heating. But with extremely low wattage (12-15 watts) .a dull, barely perceptible glow, as opposed to a bright orange, can be achieved on T1 safely. I used to fire mine in a dark room to determine the onset of the glow before backing off. Kanthal when heated, unless there are new studies, does not convert any ferrous compounds significant enough to pose a health risk. But even so, glowing any coil to fusion reactor levels is probably not wise.
Best way is to heat the coil slightly in a dim room, as hot spots will show and glow ever so slightly before the rest of the coil gets hot enough to even turn golden (in SS’s case anyway, you will have to let others with experience with others chime in on their best practices). Warming the coil to check out hotspots is not dry burning it. You can see hotspots even in a lit room before the coil will glow entirely, and sometimes a bit of colour wont hurt. Dry burning is the act of glowing the coils red hot, not just gently heating them - even titanium can be heated gently (even to a warm glow), it will be during use anyway.
There are tricks you can try to minimise any hotspots before you even attach to the atomiser. If you tap the coil lightly (back and forth) with a small but quite sturdy tool (like a watch hammer), right after coiling, while still on the jig or screwdriver, this can spring the metal back and forth enough to relieve any hotspots (this works on gargoyle hoof triple sow cow 360 nerf herders too) - some builders who wind with a drill or other automated method will find they have to do this to free the coil, and it is this action, not the precise winding, that frees any hotspots.
You can strum the coil with nylon plyers and ceramic tweezers to work out any imaginary hotspots (where they usually form) to free them up pre-warm too. I do this even though I will give my coils a dryburn too usually - people can tell me not to and that it is bad for me, well I thank them for worrying about me but I can taste the metal otherwise.
Edited to add, if you are sticking to Kanthal and N80 (N80 is not Nickel, it is Nichrome), you really have nothing to worry about in my opinion. It is only the TC only metals (Ti, Ni200) that should be approached with caution when heating, but of course, any of the above is just opinion, you will have to find your own fact.
I never knew people thought this. I thought dry burning was just heating the coils without wick or liquid. I suppose the word “burn” gives it away. Even when I clean my coils they don’t get red hot. It’s just how I prefer to do it. I dunno… I try to be gentle with coils even N80.
I build spaced coils with Kanthal and always heat new coils (I never reuse coils) till they glow red hot.
I’ve been doing this for nearly ten years because that’s what the ‘experts’ back then said was necessary to burn off any residue from manufacturing. Sure enough, when I apply initial power to the new coils, there’s always some smelly smoke that rises up from the coils for a few seconds.
Based on what I’ve been reading here, it not only appears that I’ve been doing things wrong all this time, but might have potentially been harming myself.
I do notice that after ‘prepping’ the coils with heat for a few minutes (with sporadic bursts of power) that they look dull darkish grey - rather than shiny. I’m assuming that’s oxidation from heat.
What would be best practice in my case? Should I just heat at low power for a few seconds just to burn off any manufacturing residue - and avoid making the coil glow red hot?
Thank you in advance for any and all guidance and knowledge. Even at age 68, it’s never too late to do things correctly and safely.
From my understanding, someone correct me if I’m wrong, Kanthol (Ka-1), is good for non-spaced coils because it forms a insulation layer when heated to glow and cooled a few times. Then you can touch it together when glowing and bond the insulation layers of whatever it is(Oxidation?) as you continue to hold it together while it cools. All the other metals we use do not have this property and should be spaced, at least ever so slightly. I don’t know if Kanthol gives of dangerous fumes when heated very high. I would imagine they all do if heated enough. Kanthol has a higher melting point so it may be that we don’t get it hot enough to release fumes or bad by-products of combustion? Maybe the insulation layer that form helps to raise the critical point higher than without it? All that said, I don’t like the taste of Kanthol so I don’t use it. I mostly use SS-316L. Occasionally I prefer N80 for quick firing of high mass builds that would otherwise heat slow for SS316.
Work in well ventilated area and don’t put your face over the coils when you’re pre-heating them.
