Hi all,

I have been plugging away in my garage today making ingots to use in my class rolling mill. Today I was running the torch for awhile and the pressure seems to still be fairly high, but the torch sputtered and started dripping liquid acetylene (at least that's what I think it is...lol) I've shut off the valves and stopped using the torch. My question is, why would the torch start to do that? Is there a minimum pressure that you have to have for the torch to work? (I think I read 75psi min, but it seems to still be at 200psi)... Does the gas go bad after awhile? The tank hasn't been used in about 8 months. Do I just need to let the tank sit for awhile to let the gas expand again? The valves seemed cold to the touch, so I'm wondering if it's like my mapp gas torches that stop functioning when they get cold...
