Was a freshly charged battery so I was rather confused. Other things adding to confusion: I may have a dud of an HG2 hiding in my ranks, my RX200 I double checked it on for how long it took to fire barely fired my Kanger SSOC TC coil this morning.
I'm probably not going to play around with the 26, 28 kanthal that I ordered much more. Didn't use that coil. I'm looking for more of a sub-ohm build and from what I've gathered so far that means lower gauge wire. I was using Steam Engine when I ordered wire but had not yet noticed the wattage portion affecting heat flux... doh.
That was from a Coil Master V3, with the 3.0 mm coiler. Is that considered a mirco coil? Before I order more of the wrong wire what's the best way for a noob to get some 0.5 ohm builds similar to the stock kanger coils I know I like?
Ordered a spool of Ni200 32 gauge as well. I thought this would be easy to build some sub ohm temp control coils but from the looks of things on Steam Engine it's either I can't hit a resistance that has a low ohm coil without getting a ton of wraps or a high heat flux.
Thanks for the help so far, I've done a lot of reading and watched a lot of videos on coil builds but it's not the easiest knowledge to apply, even for an engineer.
First congrats on quitting and your appreciation of my remarks.
I ran some no's on your approx build and you likely weren't pushin 10amps (assumed 28/10x). Can't speak for the tester. Haven't used one. Two ways to shape metal as you know…
forming (what a coiler does) and
strain (elongation). The later I've found with much research does enable sufficiently proximate contact (I refer to non-scientifically as
adhesion) to enable very rapid development of preliminary alumina with low voltage pulsing (annealing). It's adequate enough to deter turn-to-turn electron jump as power is applied (or increased). This suggests a balancing of the internal strain common to extruded wire. Not all of the ridgidity imparted by strain in winding is lost in the process. Another benefit which helps maintain the wind geometry under the rigors of repetitive thermal expansion. As I describe it this means the coil persists in wanting to remain a coil…in the nominal dimension it was originally wound.
Once achieved two things characterise the wire flow efficiency. First, it stops for the most part firing inside out as spaced and conventional contact winds will. From your video you see quite a bit of the centralized heat effect (overheating) resulting from contact and extremely high temps at center. This is what causes contact coils to essentially fail under high power causing the whining about them burning wicks. But that's to be expected from what is essentially a short. The second indicator of success one you have uniform end to end firing is a distinct change in temp of output vapor along with density (less diffusion). This confirms a reduction in thermal loss to air and a higher rate of phase transition. Have done this experiment thousands of times and with hundreds of volunteers, shop customers, workshop participants, interns comp builders and B&M owners.
If I can lend a hand gettin' you going with tensioned give me bump here or on
Tensioned Micro Coils. The next step. Glad to help if I can. As I said earlier, I use Kanthal to build performance baselines. Think no matter what alternatives we choose its good to have to keep us honest. For many of the reasons I mention in posts I prefer parallels for the relatively lower aspect (wire mass) relative to surface area.
Now here comes the good part. Folks I know have learned how to do this consistently become extremely effective embassadors for vaping. And frankly, that's why I'm here.
Best of luck to you hak.
