Tried 0.5ohms and it way to warm for me

[johentie]

Hey Hey
So I got my ipv V2S so i was excited to pop on my kanger subtank with the 0.5ohms.

first time trying anything below 1.2ohms.

So i put in a new juice i got (lychee) and mann it was warm! i read that lower ohms give off warmer vapor.. but i don't think i like it...unless i am doing something wrong.

i tried it at a lower wattage around 17... still too warm...
is it just an acquired vape?

i switched back to the 1.2 ohm at 18watts and it's nice for me..

Without knowing the actual wire gauge used in your coil heads, it's kinda tough to calculate coil radiant heat values.

An example of this might be:

• If the 0.5Ω heads are made from 29/30 gauge wire, at 17 watts...
  the heat flux would be in the mid to upper 200 ~ lower 300 mW/mm2 range.
• On the other hand, if your 1.2Ω heads are made using the same wire gauge...
  the HF would be in the lower 100 ~ mid 100 mW/mm2 range.

In other words, a sizable difference, for someone used to the cooler gauge/resistance / wattage. Of course, this is based on a W-A-Guesstimation of wire gauge. If your APV will run down to around 10+/- watts, the 0.5Ω head will run at temps in the mid to upper 100 mW/mm2 range.

All values calculated using "Steam Engine"... see sigline hyperlinks below.

i am not sure what is used in the atty's that came with the subtank.. i'm assuming 28gauge

IIRC the ST .5 ohm head is NR-R-NR, 26 gauge and obviously .5 ohms. No idea on wire composition. .5 on 26 gauge is a comfy vape for me, but that will ultimately depend on what atty your using and its airflow configuration.

I noticed the same thing when I got my Subtank, it is a very warm vape with the .5 coil. I have it set at 20W and opened up the airflow all the way, noticed that more airflow makes it a bit more tolerable. I haven't tried the 1.2 coil yet though, I have a feeling I might like that one better.

The OHM and watts does NOT determine heat of a coil..... The amount of METAL used to create the coil does. The ohms and watts just determine the extent and speed of the heating.

 

[Hitmetwice]

Yeah, going sub I found wide open airflow, wide bore drip tip and short strong lung inhales worked best.
One needs to experiment a little. More air over the coil will keep the vape cooler. Cheers.

are you using the same strength nic at 0.5 ohms as you were at 1.2 ohms? with more power you will also need to drop your nic lvl.

I have yet to pull the trigger on a sub tank but from previous experience im wagering 30g or 32g kanthal. i never use the wire that comes with stuff... i use to collect it for a rainy day... it never came so i threw them all away

Firstly when i first went to sub ohm lvls it was with a giveaway i won. turtleship v2, 2x sony vtc4's, and an igo-w3 prebuilt with 4 coils coming in at .3Ω
That sucker HURT! OMFG it HURT. I did all sorts of research on sub ohming and NO ONE told me about nic and pg = BAD BAD BAD BAD BAD BAD BAD in RDA's. I dripped *no exaggeration* 18mg, 70/30 pg high Grandma's Cinnamon Danish. I felt the BURN.

Though i learned just about all i needed to know about sub ohming, battery safety, and coil building; It took some time for me to learn the things i needed to know about dripping and lower resistance flavors. I vaped at .8 duals before becoming more accustomed to the warmer vape and began to enjoy it. I now really enjoy my .4 dual coil builds and .3 occasionally on my plume veil. As far as the sub tanks... erm. Take a step ladder approach. Build a .8 and see if you like it. Each person has their own personal sweet spot where flavor is good, vapor is good and you're a happy camper. As far as the heat, well i'd suggest a thicker wire and a bit more air. I tend to drill out or file away the air holes on most of my drippers... oddly enough i spent a good 5 minutes filing my plume's cyclops vents and it was utterly delightful to vape on.

Sorry for bouncing half off topic for a bit

Also, just sayin', it could be the juice your vaping. Have you tried others? And do they have that "too warm" sensation as well??

I'm happy to see I'm not the only one confused by this. Using an ohm's law calculator here is what I found: 1.2 ohm coil with a VV/VW mod set at 22W = 5.14V @ 4.28A. A .5 ohm coil at 22W = 3.32V @ 6.63A. If higher amps produce more heat, then that would explain why you get a hotter vape with a sub-ohm coil. Answer: turn down the wattage. Worked for me.

With regulated mods it won't really matter that much. Watts are watts, though wire gauge might play a part. Lower resistance coils are commonly built with thicker wire. Thicker wire takes longer to heat up, but it also takes longer to cool down. At 22w a .5 coil from 26 ga kanthal has a higher heat capacity but lower heat flux than a 1.2 coil from 30 ga kanthal. I think that means that the 1.2 ohm coil should get hotter a lot quicker, but the .5 ohm coil has the potential to get hotter if fired for long enough. I could be totally wrong about that though, so someone please correct me if that's the case.

Just tried a .6-.7 duals with 28g wire in my Fogger, and I'm in the same boat - a bit too warm for my taste. I like it colder as well, but also with 5-6 wraps tops for a quick startup time. My usual setup was 1-.8 via 30g wire.
