You could use natural gas as a blanket. Methane should work as well as CO2, and not require any bottles, and would probably be a lot cheaper. Just make sure that all the oxygen is out of the chamber before you strike the arc or you may be picking up pieces of the chamber from all over the room. Also be sure to light the exit of the gas or pipe it outside for safety. Propane and butane should work as well.
