New to vaping so when I first got my vape the guy at the shop set it up for when took the tank off it asked me if I had a new tank on and I said yes now I have no idea how to change the ohms back to what they were when I first got my vape FYI still using the same coil and tank
First... tell us which mod you are using, most likely several people have it as well and can give specific advise. But as a new vaper, you should read the manual as well.
eta: oops... TopBox... don't have one of those myself.
If the mod asks "New/Same"... you're in one of the Temperature Control (TC) modes. You should only use TC-able wire in TC modes... and use the correct mode.
Conversely... you should never use most TC wire in Wattage mode. Stainless Steel (SS) is a common exception... it's "dual use".
TC works by setting a register with the "room temp" resistance value (whether you "lock" the res or not). If you answer "New" with a warm tank which you just refilled... the TC calculations will be off. You'll need to allow it to cool for a bit, 15-20 minutes maybe, then put the tank back on and answer "New" if the mod asks. This will "repopulate" the register with the proper room temp resistance value. And you're off to the races.
If nothing else... you MUST remove the installed coil head and determine what the coil wire material is. If you see Ni (Nickel), Ti (Titanium) or SS (Stainless) etched on the body you know it's of that material and which "mode" to use. If it has none of those, it is probably Kanthal or NiChrome wire and should only be used in Wattage mode.
Last... I'm going to "tag" a couple of mods (
@Whiskey @Huckleberried ) and ask them to move this thread to a section where you'll get more eyeballs and specific answers to any questions you have.
