If you use a sealable container of some type, and use copper for the
electrodes, the copper oxidizes, removing most of the oxygen from the
air leaving mainly nirogen, a little bit of argon, carbon dioxide, water
vapor, and traces of other stuff. You don't necessarily need to flush
out the gas and fill with nitrogen - however, purging the container with
dry nitrogen WILL prevent you from having any potential problems with
condensation later on.

Safe gappin' to ya'!
