I use the premades at the moment so this should be ok and i torch them everytime, when i don't use premades i use kanthal and silver so maybe its the nickel from imeos premades (he uses nickel right?) cause i have this problem only since i use these i think, i will try my normal setup then. Thanks, haven't thought of the metal from the wires
i also wrapped them pretty tight after reading that this can be an issue too
