Everyday name for compressed gas cylinders: argon, 75/25 and CO2 for shielding, oxygen and acetylene or propane for torch work. Bottles are chained upright, capped when moved, and stored with oxygen separated from fuel gas. Acetylene is used upright only, and its draw is limited, commonly to about one-seventh of the contents per hour, or acetone is pulled out with the gas.
Argon bottle's on fumes, swap it before you start that root, and chain the new one up.
