40 Cubic Foot Gas Cylinders
I have a pair of these, both are customer owned and exchangeable at any Airgas.
These most recently held pure Argon for TIG welding, but they (airgas) will happily exchange
them for C25 for Mig welding, I know this from experience. They're both currently empty, and
cost around $30 each to exchange for full ones.
The best price Ive found online is $179.99 each for 40 cubic foot units, so I think $100 each is a fair price for these.
Located between Dayton, Ohio and the Indiana border.
Shipping is available.
