Product details:

New 20 cuft steel oxygen cylinder is great for medical and industrial applications. The oxygen tank is made of high-strength steel construction and thick tank walls to stand up to the most demanding uses. Oxygen is used in small amounts as an addition to other gases in welding applications; typically, as 2-5% addition to argon. It enhances arc stability and reduces the surface tension of the molten metal, increasing wetting of the solid metal.
