The article offers tips in selecting carbon dioxide laser gas equipment by the Allen County Fabrication in Lima, Ohio. They use a TRUMPF L3050 5kW carbon dioxide laser for cutting variety of materials so they need a wide range of knowledge that will optimize the gas withdrawal from cylinders. It is important to consider that the three major contaminants that need to be minimized by specifying gas purity levels include the hydrocarbons, humidity and particulate matter.
