Hello and welcome to the forums!
Let's start at the top.
Generally there are two reasons that can create the hated burnt taste. Too much power or not properly priming the coil. Do you know what kind of battery you have? Did the battery come with the tank?
As for properly priming, all that means is when you put a new coil in, drop a few drops of juice onto the holes on the side of the coil, you should see the juice get sucked right in. Keep doing that until it's not absorbing anymore. Then just to be safe, put a drop or two down the top of the coil straight into it. Then fill it up and let it sit for ten minutes or so. Then take a couple long steady inhales off it without firing the battery. It should be ready to vape now. So on your battery, you need to start at a lower power setting and work your way up. But i'll get more into that in the next part.
So three coils came with your tank. They like to put a couple different kinds in so you can see what you like. Now it should come with a 0.5ohm clapton coil, I bet anything that's the one already in the tank. It also comes with a 0.15ohm nickel coil. That one is used for temperature control, which you can do if you got the battery with the tank. But we'll put that one away for a little bit until you get the basics down. The last coil is a 1.5ohm stainless steel coil. That one is just your standard style coil. Now, as for power on your battery to avoid the burning taste. You want to make sure you start low. Now, unfortunately I'm unfamiliar with the clapton coils and am unsure the recommended wattage for them. Luckily kanger prints that on the side of the coils. They'll have a range on there, for instance my 0.5ohm stainless steel coils say (15-60watts) on the side of the coil. So when I put a new one in and I've primed it and it's good to go, I start at the low end, so 15 watts. Then you simply move up every 5 or 6 puffs by 1 watt until it's doing what you want it to do and is comfortable.
And yes for settings on the battery. It's dependent mostly on the resistance of the coil. The ohms. Less resistance usually means it takes more power to fire it.
The three types I use in there plus I use the rebuildable coil that comes with the bigger toptanks and subtanks, just to give you an idea.
0.5ohm regular coil - Start at 15 and it'll be performing nicely at around 20 watts
1.2ohm regular coil - Start at like 8 watts and these will be going nicely at around 15 watts
0.5ohm stainless steel - Start at 15 but these can go higher, so they'll get to around 25-27 watts.
My nautilus uses 1.8ohm coils, so those I start at like 7 watts and they perform best around 10.
So basically, the less resistance, the more power they take. The material the coil is made out can change things a bit but, like between my normal .5's and the stainless steel ones for instance. But I wouldn't worry too much about that.
We just need to get you up and running and comfortable.
That all looks like a ton of information, and that's just because I'm a rambler and try to explain in great detail. But I promise it's not that much to take in once you start doing it.
