Thanks JERUS. maybe this isn't good ? In this thread but what do you mean 150w build? I'm still learning and will be buying pre made coils but until I learn more won't attempt. When you make your coils and burn them then test them is that what tells you how high it can go? Sorry if dumb question.
I just meant I had a build that could handle 150w without causing a dry burn, but the flavor was lost on it. I've had other builds that could go to 200w before that happened and 160w was actually very nice. Just lots of things involved. One of my best builds is a 1.11Ω dual coil build at 45w, it's great. Not as much cloudage but flavor is on point compared to my 150w+ .08 staple build.
The wattage you use like everything has multiple elements at play, airflow, wicking, and the coil structure will play major roles. If it doesn't wick juice quickly or hold much juice inside then it won't be able to handle higher wattage. If the airflow is low your coil is going to run hotter which means you likely want to use lower wattage. Coil structure is more than just resistance, but also mass and material type. A ~.2Ω kanthal fused clapton will be 26g cores most likely, and be larger than a Stainless steel fused clapton which would probably be 28g or so.
Anyways, I have a few "rules" for guessing wattage for myself, but I just use them to start then adjust to fine tune.
- more mass = more wattage (so going from a 26g build to a 24g build I'm going to turn the wattage up)
- lower resistance = more wattage (26g Kanthal vs 26g Stainless Steel I'll probably use more wattage on the stainless steel being lower resistance, but not much as stainless steel also heats quicker anyways)
- .5Ω start at 40w, .3Ω start at 60w, .2Ω start at 75w, .1Ω start at 90w (sometimes I'll go up, sometimes down, but that's where I just guess as my starting point).
As for dry burning, it's always better to go low for that, just pulse it until it glows. If you heat up a coil too much it won't necessarily melt but it will soften and droop, losing it's shape and ruining the coil, which sucks. So like my .1Ω coil I might mount it and work out the hotspots and get it balancing at 65w, once it's set I'll wick it up, prime it, pulse it a few times as I blow on it, then prime it again and put the tank back together and fill, then crank that wattage up to around 90w. Now when I dryburn to clean I'm lazy and usually just yank the cotton out and pulse it until I get a nice glow and all the gunk is gone, just being careful not to hold the power down, just like half second pulses over and over until it's a nice orange, not going to that blinding glow.
Anyways, this is getting long and I'm rambling, just remember that wattage isn't isolated, it's simply the power you're putting in. Each build (coil/wick/airflow/etc) may prefer a different amount of power to achieve similar results.
