Argon can be stored in a number of ways, depending on the amount that needs to be stored and the application for which it will be used. For small amounts, argon can be stored in cylinders or tanks. Larger quantities may require storage in a cryogenic tank.
When used in welding applications, argon is often stored in cylinders that are connected directly to the welding equipment. This provides a ready supply of argon to the welder and eliminates the need to transfer the gas from one container to another.
