Default Re: airgraver power supply

I would not use argon in any closed shop, too dangerous. Instead, the nitrogen bottles are relatively cheap and are dry. We used nitrogen to keep a blanket of dry air in the high voltage transformers in the transmission/distribution substation in order to eliminate any moisture in the system. Any moisture in a 500KVA transformer is disasterous and unhealthy for anyone nearby.
