- OK, so I am not new here. I have a lot of know how through these forums and through experience. The problem is that I have "popped" 3 coils in the last 3 days. I have never done that with my 32 Kanthal (not sub ohms) Started building with 30 Kanthal (not Sub ohm) and cotton and blew 3 in 3 days. Could it be bad wire or something else? A real pain when out and about. Works well all day then suddenly 0 resistance on coil. Phoenix dripper at about 1.5ohms Has anyone else experienced this? Any help would be appreciated. Thanks in advance.
