This saves me from starting a thread. I have 2 large O2 tanks (200 and 300?) And just got a tig torch, so I need argon and an argon/co2 flow meter. My tanks are partially full and 20 years past hydro though. I also have 2 40 cf acetylene tanks. Anyone hazard a guess what a hydro and 200 cf of argon will cost; $50? $100? $200? Or would I be cheaper to do 40 cf acetylene swap for 40 cf argon and avoid hydro
