Flame cutting is a process used to cut Steel. This process can also be called different names such as Oxygen & Acetylene cutting, Oxy-Acetylene cutting, Oxy Fuel Cutting and Steel Burning among many other terms. It is done by heating up the steel with a burning Flame that is generated at the end of a Torch head. This technology uses pure Oxygen, under high pressure that is combined with a gas-fuel, such as Acetylene, Propane, or Natural gas. This Flame produces intense Heat with the Oxygen-Fuel mixture, and additional High pressure Oxygen pushes or blows the melted steel out of the way as it moves over it and cuts through the steel, leaving a relatively smooth finish. A High Purity of Oxygen is needed to achieve the highest quality cut finish and this presents a potentially highly dangerous situation. All Federal Law and Safety requirements and procedures are regulated by OSHA, (Occupational Safety and Health Administration) and can be found on their Web Site.
