Let me see if I have this right....

[Bean8379]

Using a variable wattage mod, it has been my belief that at any given wattage (for example, 20w) a higher resistance coil will get warm/hot faster than a lower resistance coil. Yet I compared two possible builds in my ohm calculator app, a 1.13 ohm coil and a 0.75 ohm coil. The calculator tells me that the higher resistance coil requires more voltage to achieve the same wattage (20w). The 0.75 coil requires 3.87v to achieve 20w, while the 1.13 coil requires 4.75v to achieve 20w. Yet going by amps, the lower resistance coil actually pulls more amps (obviously). So which is it, does the higher resistance coil warm up faster? Or is it the other way around? I know on a mech mod, a lower resistance coil takes a bit longer to warm up, but on a regulated device the output is constant so would the coil that requires more voltage to achieve the same wattage take longer to warm up? I'd like to know because I feel that whatever coil is going to warm up quicker at any given wattage would be best for flavor.

With VW, it's not so much about the resistance, volts or amps. Wattage is wattage. Mech users erroneously associate current with heat because that is indeed the way to get more power out of a mech. But that is to say the real reason higher current leads to a hotter coil on a mech is because it translates to more power.

High voltage accomplishes exactly the same thing as high current. A high-voltage/low-current setup at 50w does the same amount of work as a low-voltage/high-current setup at 50w.

The way to approach the issue of heat and ramp-up is to ask yourself how much power (in watts) it would take to heat up a coil of such and such size. At a given power level on a regulated device, a bigger coil will always heat up slower than a smaller one will. The same goes for mechs, really. Your options are just more limited in that regard because you have to build to resistance in order to get to the desired power level. You have to strike a compromise between the desired power level and surface area/heating properties.

Well, I'm happy to say that I figured out what the trick is. First, let me say that my problem with flavor was twofold. First, my coils kept oxidizing. I now believe that I know why. I was pulsing them way too much and causing ash to build up. I changed the way I build coils. I don't pulse them at all. Instead, I wrap them and then heat them with a lighter to get them as tight as I can by squeezing together after I heat them. Then I spray them with alcohol (70%) to remove the ash that builds up. I let them dry before installing them. Then I wick and juice. I do pulse the coil a very small amount at this point in order to draw juice into the wick. The second part of my problem had nothing to do with watts at all. It had to do with warm up time. As in I wasn't giving the coil any time to warm up. I would hit the fire button and immediately start inhaling. I kept trying different wattage settings all the way up to 20w, and the flavor would either be hardly there at low settings, or taste nasty if I turned it up too high. There was almost no middle ground at all. A few flavors tasted ok at medium settings, but that was it. So after I just installed a brand new coil and got it wicked and juiced, I decided to give it time to warm up. I was vaping peach at 7w, and the flavor was pretty damn good. Oh, vapor production was good too, I mean not blowing ridiculous clouds at 7w, but definitely a nice thick, consistent vapor. I then switched to captain crunch, and I eventually turned it up to 12w, but again perfect flavor and vapor. I'm running a 1ohm coil with organic cotton. I pull a bunch of cotton apart so I can get all the fibers running the same direction, and then I wick. I'm really glad that I figured out how to get this mod working for me, I've had it for 3 days now and until now didn't think the vape was any better than my mech. I would bet now though that I'd have been happier with my mech if I'd learned these things starting out. But this mod is really nice, it fits square in the palm of my hand and the battery lasts all day (Samsung 25r5). I could chain vape all day at 7-12w if I really wanted to. I'm extremely pleased at this moment lol.

Told ya, 10-12 watts on a 1.8 and 18-20 on a 1.0. Take it from there.
Just my opinion but high wattage and sub ohming isn't necessary and could be dangerous.

Doing good there bud. The only thing I can suggest is to torch your wire a bit b4
you start winding. Makes it a little stiffer, preburns whatever crap on it,
and makes it easier to wrap. Then as you did, install, heat, squeeze together.

Might take a draw w/o firing if from a tank then fire a second or two depending on how
long it takes your coil to get cherry and toke away.

 

[Bean8379]

I tried torching it with a lighter before winding and I also tried heating it on a burner, neither one seemed to do the trick. I'm finding that there is some variance with wattage depending on what juice I'm vaping as far as what setting gives the best flavor. Peach and peanut butter both taste best at 7w. Captain crunch and chocolate mint taste great at 12w. Haven't tried anything else since building a new coil, but I might try some chocolate marshmallow fudge here. Still gotta rebuild my tank. Got a coil ready, was just letting it dry because I rinsed it out. Not sure if I should put peach in it or orange tic tac, but leaning more towards orange tic tac. Built two coils exactly the same, one for my dripper and one for my tank. Certain flavors just don't taste right to me if they are even a little bit too warm. But I'm finding my sweet spot with each one, and happy with the results so far.

Figure the dark like chocolate marshmallow fudge or choco anything will be better at higher wattages or voltage.
The lighter doesn't really work well for torching.
Goto tmart.com and get a five dollar lighter/torch. Make sure you order from their US warehouse.
You can find 'em on Ebay but remember to put only US as a filter.

Those suckers will torch your wire good, won't burn your fingers, and don't use very much butane.

You'll find that different flavors may need different approaches for the best flavor, with any mod. And all anyone here can do, is offer you suggestions.

I rarely use more than 25 watts in any build. Unless I'm checking for a change in the flavor.
And I still use the occasional 1.0+ ohm build on some flavors.

I use TC and Power modes, and sub ohm.
My Kanthal remains the same, 24 & 26 gauge. Nothing fancy as far as builds go.
My Nickel, is 28 gauge twisted. Just a simple and tight twist. Again nothing fancy.

The bottom line is, whatever works for you is fantastic in my opinion.

 

[Powerman]

What wire are you using? The only thing that oxidizes is Ti. And you should not be torching it. You pulse it at low watts just to warm it. There is no "ash". Kanthal is best non TC. You should not be using Ti without TC. And as far as oxidizing, you shouldn't be using anything that does.

 

[Bean8379]

When I dry burn kanthal to get the gunk off, after a few times I can see what look like rust spots. I have also noticed a bad taste when this happens. Using 26g kanthal. No tc. When you burn anything metal with a lighter, carbon builds up. This is what I referred to as ash. Spray it with alcohol and it cleans it off. It may be possible that the reason my coils were turning rust colored is because I was dry burning them at too high of a wattage.

 

[Powerman]

Got it. Na, probably not. You are not getting it super hot. Burn em. Get what ever off. The ash is just carbon. Soot. But you can certainly get kanthal cherry red.

 

[Bean8379]

Then why the rust color and bad taste?

 

[Powerman]

Rust is from water. Color wise, no idea. Kanthal isn't oxidizing from heat. My guess is you haven't burned all of whatever it is off. Cherry red... Clean it in alcohol if you want. But it isn't the red hot that is doing it.

 

[Bean8379]

I wonder if some people need higher watts because their taste buds are destroyed by smoking that they can't taste their vape very much? I quit smoking 3&1/2 years ago, so my taste buds are probably fine. Maybe that's why I get great flavor at 7-12w, dunno.

 

[Powerman]

Doubt it. I was a light smoker. Off and on last several years. Vape can taste great, but I don't do it for taste. I do it for nic. If I want to taste something, I can have a jolly rodger. If I want apple pie, I'll get a slice. My taste is fine and I love my crown.

 

[Bean8379]

I do it for the nicotine, but the flavor is also a benefit for me. Because I am a diabetic, I get to taste all these great flavors without constantly spiking my blood sugar or putting on extra weight. Now nicotine may have some effect on blood sugar, but at 3mg, I'm sure it doesn't have as much of effect as eating all these things would. People like high watts for two reasons. Either they aren't getting enough flavor at lower watts, or they want bigger clouds. There has to be a reason some people can taste their vape at lower watts and others can't. Maybe it's not smoking, but I pretty much guarantee you if you compare two people who are new to vaping and one of them is coming from a heavy smoking habit, the heavy smoker probably won't be able to taste their vape as good as the non-smoker. It's definitely got to be something to do with taste buds either way.

Nope I started at low wattage, high Nic, and had great flavor.

Stepping up to sub ohm allows me to use less Nic in my mix. There's better atomization, so the delivery is better. I watch my wattage also. And vary it as needed to obtain the best flavor.

One side effect of sub ohm. The coils don't need cleaning as often. And temp control makes sure my cotton stays clean.

Different strokes... Smokers can't taste stuff. That's known. If it's about taste, they would go lots of vapor to little. But most go from little to more. Natural progression.

VG flows less, takes more heat, but is smoother. High nic is more harsh. More VG with less nic concentration is much nicer for me than the opposite. On some of my juices the Crown gives too much flavor. I'm not chasing clouds, but I like seeing an exhale. Not stealthy, but who cares? Just like smoking.

So I don't have a Crown at 85w because I'm trying to get more flavor and I can't taste. Flavor is awesome, vape is very smooth, and it's more like smoking. I actually liked the act of smoking, I just always hated burning tobacco. It was just about the nic, and I still get plenty of that. That's why I went from Vuse, to eGo One to a Crown/ DNA 200 in the matter of 8 months.

 

[Bean8379]

Here is the situation. I kinda feel like an idiot lol but it is what it is. So awhile back when I had my first mod, a mech, I would notice that my coils would gunk up really fast. So in an effort to alleviate this "problem", I stopped dripping across my coil and would only drip onto the cotton that was outside of the coil. I did not make a connection between my doing this and a loss of flavor. I was at a vape shop tonight and someone let me try some of their juice. They were even kind enough to drip it onto my wick for me. I noticed that they dripped across my coil. I hit my mod and the flavor was on point. When I got home I had to put a new wick in because one of the flavors I sampled was an apple pie flavor that was very heavy on the cinnamon and I could not get the cinnamon flavor out of my wick no matter how much I dripped other juices, all I kept tasting was cinnamon. So when I put the new wick in, I decided to try dripping across the coil, and again, the flavor was on point. I still like to adjust the watts for different flavors, but none of my juices taste bad even at higher watts, I just turn down the watts with some of them because they taste better. Peanut butter, for example, doesn't taste anything like peanut butter at higher watts. I've also noticed that none of my flavors taste dry, where previously all of them did. I attribute this mostly to the fact that I was probably burning my wicks all the time. I have seven flavors of juice right now, and I can taste all of them just fine.

If your concerned about how fast your coil comes up to temperature when you first press the fire button, you need to know what the "Heat Capacity" number is for the coil you are building.

Look at this link: http://www.steam-engine.org/coil.asp?r=0.8&hfnw=15&awg=26&id=2

Here is an example:

Kanthal A1 / APM wire

26 AWG

Single Coil

Target Resistance: 0.8 Ohms

Inner Diameter of Coil: 2.0 mm

Leg Length: 5 mm
___________________________________

It will take 7.47 wraps to make this coil (7 wraps rounded to full-wraps)

The "Heat Capacity" is 29.87 mJ/K ..... The lower this number, the faster the coil will heat
