Low pressure fuel cylinders like acetylene and propane should only be opened 1-2 turns in case you have to turn them off quickly because of fire. All tanks should be closed completely when not being used. I myself have emptied many a cylinder by leaving them on. Just fyi if your mig welding you should be using a 25/75 mix and tig uses 100% argon. Happy welding.
