In my city vape shop doesnt have a khantal wire , they only have nichrome wire which has low ohm , i want to mtl style vape , can i use low watt with low ohm coil??
Well the vape shop only have 24 awgYeah n80 wire will work fine for a mtl coil. Get 28gauge if you can. It's only slightly lower in resistance than kanthal. You can make the same ohm coil - just add an extra wrap or two.

I use convergent rda with mtl airguide , and mtl need long ramp up time isnt it?It’s not impossible to do it with 24g. It will take a fairly long coil though to get it to a good ohm rating, and @AngeNZ is dead right about the long ramp up time. Coil will be big enough it won’t fit in some attys. What atty you using?
Normally no. One of the nice things about MTL is it generally doesn’t. That thick 24g wire will only heat so fast though and you’re going to need quite a bit of it to get the ohms up. 28g is really much preferable. Only bright side is that thick coil will take forever to wear out.I use convergent rda with mtl airguide , and mtl need long ramp up time isnt it?
You got it. Thinner wire makes for a smaller coil.Just so we know we're talking about the same thing, ramp up time is how long it takes the coil to heat up enough to produce good vapor.
MTL does not have to be long ramp up. Higher resistance at low wattage with simple coils can ramp up pretty fast. It's all about the mass of the coil. Bigger coil takes more power to heat the same as a small coil.
I have never really understood the relationship between resistance and the style of vaping (MTL or DL). More or less by accident, I started MTL vaping with very low resistance coils (Ni200 30Ga, 0.10 or even less) and it always worked out fine for me.Get this: Resistance doesnt matter.
Get thinner wire. There is no other way getting a good mtl/low power vape.
Ramp up is a part of it. Large/big mass coils are worthless if you intend to throw 10 Watts at them. If you try to mtl and just use more Watts to get them going, the limited airflow doesnt cool that huge coil enough, resulting in hot whiffs of thin vapor. Thats not a good vape.I have never really understood the relationship between resistance and the style of vaping (MTL or DL).

So you're saying it's all about ramp up time?
So if you’re saying ‘big mass’ coil, this means a coil with a lot of wire (eg Clapton and or lots of wraps) or a thick wire?Ramp up is a part of it.

You have to build your coil with those things in mind first and foremost. What resistance you end up with is totally irrelevant (unless you use a Mech); the size and mass must be fitting to your airflow and intended power. Again, do yourself a favor and forget about resistance.
So what i need? A small coil with small resistance or big coil/long coil with high resistance?
Or if you want to go ultra-low, the same coil in Ni200 30Ga would be about 0.07 Ohm (close to the lower limit of most devices)I do a mtl 2.5mm id ss316l 6 wrap coil which comes out around 0.6ohms. I vape that at 15w - because of the thin wire - it heats up immediately (ramp up).
The same 2.5mm id 6 wrap coil in 28ga N80 would be 0.9ohm. Using kanthal a1 it would be 1.2ohm
