Alright well I got an Ion with an on/off asa and when i gassed it up the first time i had the nob on the on/off turned out. I wasn't getting any pressure but I believe it was because I changed the regulator. The next time I put my tank on and it blew the oring off the tank I had the nob turned all the way in this time. So I know this may sound newbie but I am not exactly sure how to sue the on/off when do I have the nob turned in and when do I have it turned out.
thanks
