the electrodes can last you a life time as long as it is taken care but since inside the glass it is filled with gas if you break, or even the slightest crack the gas can leak out. With the purchase of this machine you already receive a set of the Neon gas electrodes (3 of them-spoon, mushroom, pen shape). You may purchase Argon gas (purple) separately if you would like. Since we are the maker if you ever need parts you may get them all from us.
