Never heard of doing this.
SS will rise in resistance, but will fall back as it cools.
It rose and never went back, even when I turn the mod back on after awhile it reads a steady .16....it stinks because I love the alien Clapton but I just need so many wraps in order for it to to be of any use

Nichrome usually has a lower resistance before dryfiring the coil. After that it remains stable at a higher level. The jump can be up to 0.1 ohms in a dual coil configuration, depending on the coil and its number of cores. At least to my experience.
Going mech isn't the smartest move in this case however, as the low resistance is due to shorts inside the coil. And noone wants any kind of short on a mech.
So just dryfire the coils independently on a regulated device and you should be fine. Install the first coil. Dryfire. Insert second coil. Dryfire again.

With the alien Clapton wore I have I need a significant amount of wraps in order for it to ohm our just around a .16

Yeah... That's kinda what I thought.

Every tried using a Lower Mass set-up?

I’d love to...do you know where I can find some clapton type wires?

Sorry. I'm not really a Clapton User. I was thinking more along the lines of Non-Clapton Wire.

I find I can get about the Same Hit from using Single Wire. Also don't need like a Gazillion Watts to Drive them. Or the Slow Ramp-Up/Ramp-Down times that High Mass Coils can have.

I was doing this on a mech because the build was too low for my regulated so I had to dry burn on there to get the resistance up (the build was safe for it).
Yes but just to pulse fire so I can get the resistance higher
Was about .10 and then after pulsing it jumped up to .16 and has been steady there
Have you given @Baditude blogs a read?
I haven’t...don’t really see the relevance though
Reading them are relevant to keeping you from becoming a statistic. ;)

Any reason why you need to try to vape a build that low on a mech with your current experience level? Not dumping on you, but based on some of the questions you've been asking in various threads, I question if you know enough to be safe with a mech.

Just my 2 cents. Please do some research as has been suggested. Hate to see updates here with a venting or battery explosion resulting in the near future.

If your regulated device won't fire your build, it's not wise to move it to a mech.
I know all about my safety, but thank you for your loving concern. Maybe take the time to read and understand that I’m only dry pulsing the coils on the mech, to get the resistance up, and then vape on my regulated
Please, enlighten my on why I have to get back to basics...do you even vape bro?

A Beginner's Guide to Your First Mechanical Mod

Some indisputable truths:

-I have never heard of pulsing a coil to increase coil resistance. Sounds like some misinformation to me. One pulses a coil to remove/burn off any machine oil that may be present on the wire, or to soften the wire enough to reshape a homemade coil if need be.​

-If a coil's resistance is too low for a regulated mod to fire it, then it is too low to fire on a mechanical mod. There is a very good reason why a regulated mod refuses to fire a coil when the resistance is too low. If you don't know why, then you have no business using such a low resistance on a mech mod.

-IMHO, it's pretty foolish and illogical to attempt to use a high mass coil on a mech; save those coils for a high wattage regulated mod if you MUST use them. The ramp up time to heat up a high mass coil is unreasonable on a mech. Simpler low mass coils make more sense for a mech, whether a single or dual battery mech mod. Claptons coil question

-Observing a spark or flame means something is dangerously amiss with your setup. It could mean there is a short circuit anywhere along the current path from the battery to the coil. The LAST thing you want to do is hard short a battery.

Or Advanced Vapor Supply or Kidney Puncher, I think.

I'm not a major mech user, but I am finding your technique on this a bit puzzling, although I guess I do understand if you are trying to get a build to a resistance that "works" without too many wraps or too wide a diameter to fit. I just think it to be somewhat cumbersome and I also agree with others that if you are worrying about "sparks" of whatever sort and your atomizer, well, a mech would be the last thing you would want to test/do that on.

If you haven't tried any simple round builds or even something like ribbon wire etc., well, I think you should. That, or build a single exotic coil. Either will improve your resistance level and result in less mass in your build. If you are "designing" for a regulated mod, your build shouldn't have to start out so low that you can't even START on your regulated mod. I do understand what you are doing, but if something goes wrong-- anything-- you don't have even the faintest way to control for that with safety.

Also, for any mech user, experienced or not, I think there will be offerings for mech users and battery safety on Baditude's blog. I can almost guarantee that you would learn SOMETHING useful. Your reluctance to do so and "cherry picking" what responses you think are tolerable is not a good sign. New users who learn and experiment more take most posts into consideration before quickly arguing with them and/or refusing to take advice from them.

It IS particularly frustrating WHEN it happens, as those are the users I worry about. I have spent a long time researching mech mods, including following many threads on the topic, as I own one and will (one day) vape it. I have also "learned" there are those who are open to advice/new information (even BEFORE they can directly understand "how it pertains to them,) and I tend to find they have better outcomes (safety, but overall satisfaction with vaping builds, etc.) that those who stubbornly refuse any advice that seem "useless" to them.

If I find advice useless, I tend to research it first, prior to ruling it out of hand.

Good luck,

Anna

+ a funny rating. Reading these posts (not yours) and imagining them in my mother's voice.:eek:

If you were pulsing to get the resistance up, then I assume it was a new coil and not an old one you were dry burning to clean?

Let’s rephrase the question, since some don’t understand that this mech was a parallel setup with more than enough amps to go around...

What I’m really trying to get at, is can I use this RDA, if the build is safe, or should I throw it out because of the spark and just get a new one? Meaning I put a new build on it and all is good, or no, don’t use it joe because the spark might of done damage or something like that

So when I went to dry fire my coils to get out the hotspots, there was a small, quick spark, then everything was fine. Has this ever happened to anyone? Is it normal? Should I throw away the RDA?

Joe the burning sparks @bombastinator refers to is accretion scorching off resembling those of a 4th of July sparkler. What you are experiencing is an electrical arc. I would not vape a build in that condition particularly at the resistance you describe. Not if I wanted to keep half a brain. That you ask suggests you're smarter than that.

Good advice here if you can take it.

Good luck. :)

The RDA should be fine, unless it keeps doing it. The coil could have snapped if you say a spark and it wasn't used so there was no gunk on it.

I would assume, since you saw a spark and then got a big resistance jump, that you may have had a small trimming from your wire laying on the deck and touching the positive post. That would've caused a spark and, once it came out of there, your ohms would go up. Hitting it one time like that wouldn't damage the RDA, unless it's an old one with a really low grade insulating materiel.

No I’ve already changed the build...just don’t know if I should continue using the same atty or not

I think you probably could. You won't know until you try it. If you have an ohm's meter, I would probably test fire on that for a bit, before putting it on anything.

It's kind of hard to say given that it's not entirely clear what is causing it, and etc. One spark shouldn't completely destroy an atomizer unless it's really amazing. I'd say build higher or a single coil if you can do that, and test it on your regulated mod if you don't have an ohm's reader. I think it would be safer than test firing it on a mech, let me put it that way. Honestly, and ohm's reader would be ideal, because you could inspect and test your build BEFORE you wick it, on a relatively safe piece of equipment. Otherwise, I personally would only test the atomizer on a regulated build, not a mech (regardless if it is one or two battery) so that will require a build that your regulated mod can actually READ even cold.

That would be my recommendation, to test the atomizer. But I don't think one spark should destroy it, the question is now whether this is going to be repeated and if so, what will happen. But no one can give you a 100% guarantee if it's safe or not. Etc.
