The unique formulation of Chem-O-Lene fuel gas makes it unlike any competitive fuel. Composed entirely of combustible hydrocarbons, it burns consistently from full to empty cylinders and all pressures between. But the most significant performance advantage lies in its higher flame temperature – temperatures higher than attainable with any existing fuel! This means both greater cutting speed and relative freedom from slag. And its flexibility in application allows Chem-O-Lene gas to heat treat with a minimum of oxidation and without use of mufflers. Chem-O-Lene gas cuts high carbon steel with no apparent hardness penetration.
