@ Scott where did you go to. I called airgas they do not recertified tank. They only refill tank.
the one i got from you, i went to get it filled/swapped and they did not have another bottle the same size as mine, so they just refilled it. can't remember if it needed to be re-certified or not, i did ask them, can't remember what his answer was though.
my suggestion is, just go to get it filled and see if they will swap it. they should check the date on the bottle.
I go to a welding place right down the street from me.
