AirGas C25 mix cylinders... Straight CO2?
I have my own "300" cylinder (9.25" x 55") that AirGas swaps out for me about once every 3 to 5 years. My bottle was down to 250#, so I've been watching it close. Well, yesterday my wire spool ran out so I figured to get both since it's a 30 mile round trip. Called them and they said they were out of stock and the cylinders had been ordered for over 2 weeks. This is not a one-time thing either, the same deal happened last time I needed a fresh bottle. Is it my local AirGas store or is this a nation-wide phenomenon? They have a fill plant 75 miles away in Houston (2 plants actually), so I'm having a hard time seeing how they are "out". Think it's because I have my own bottle and don't rent per month? I hate having stuff to do and not having the equipment to do it with...
Anyone ever try MIG welding with straight CO2?
