WebFeb 25, 2024 · A PSA nitrogen generator, for example, works by using a carbon molecular sieve (CMS) to adsorb, or bind to, the oxygen, argon and carbon molecules in the air. The CMS removes the other molecules from the stream of compressed air flowing through the generator and leaves a pure stream of nitrogen behind. A PSA nitrogen generator typically ... WebMay 3, 2024 · Oxyacetylene Welding Torch Hose. The oxyacetylene welding hose connects the gas cylinders to the welding torch. It is a channel that transports the oxygen and acetylene gases from their respective cylinders to the welding torch. The pressure in an oxygen cylinder can be as high as 2200 psi (15,169 kPa), which must be reduced to a …
