probably going to happen when using ego threads for a mech, i hate ego threaded tanks for that fact. Your the second person I've seen in two days that are using tanks style attys on mechs, most of the coils are made to use with lower watts, they do make a .8 coil that works with the aero tanks. The protank !! has just always had issues from what I read, the mini is not designed to use on a mech mod without a kick, and an adapter, yet it will still leak due to the fire pin being exposed in the ego style tanks. Grab an Aero tank and some .8 coils and you will probably do a lot better.
