Ended up going over to AirGas to get gas for the MIG. Bit of a punch out the gate with bottle purchase but exchanges are $90 but with a 60 Cf tank that will most likely be infrequent occurrence (unless I forget to shut off the valve :rolleyes:)
I think most everyone already told you but be sure and leak check all fittings once you hook it up. And always bleed pressure off the regulator when not using it, and never stand in front of gauges when cracking them open.
