Im new to vaping but i started out with a eVic VT. You get a nickel and a titanium coil, my question do i need new atomizer coils or is my whole thing shot? My pen fires but second later it says protection and wont fire(this is all under temp/fahrenheit) but when i switch to watts it kicks out smoke but it taste burnt and this is all with the nickel coiling. When i then put on my titanium one it tasted horribly burnt way worse than the other. My friends did have the temp cranked up to max(600 F) but we used it alot but on lower settings(430 F). PLEASE HElP dont want to buy another 120$ pen.
