how often do you usually have to rewick ?
When your flavor begins to become muted and/or taking more effort to vape, as well as any leaking.
Your colis will last much longer when cleaned at the first signs or either. Some folks vapes a coil to the point of the wick becoming totally fused to it, making burning off to clean (with vape juice still there) very difficult. Sometimes one can build a new coil in less time then cleaning a very neglected one.
Given the prices of prebuilt wire (not packaged coils), it's best to take care of these. A pack of 10 or so premade wires will last a long time, given the build quality is great & wick changed regularly. Stainless Steel (usually SS316L) will normally outlast Kanthal, and have a better taste.
While I can't speak for everyone here, can for those I know who vapes, all who has made the leap to SS316L has never reverted to Kanthal on RBA's.
For larger models, such as the SMOK TFV12 Cloud Beast, 24 gauge wire is usually needed, for smaller RBA's, then 26 or 28 gauge is fine. It takes some tinkering around & a bit of luck to find the 'sweet spot' for every one of us. Even then, on a different RBA, may require playing around again, although if the size is near the same, what one is using being good starting point.
Whether one is vaping for flavor or cloud chaser also makes a difference.
One thing not to overlook, as others has mentioned, being safety. Use an ohmmeter to make sure things are right to prevent 'Check Atomizer' warnings before wicking & vaping, will save a lot of time. I always check the first built coil before doing the other, that way will know if I can proceed with that build
or start over.
You'll get used to this & by purchasing wire in 100' spools, can save a lot of cash when beginning to build your own from scratch. I use TEMCo wire, sold on eBay & free shipping. They have many options, here's one of my favorites. Free & fast shipping also!
