    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    Operating cost for a gasoline torch is typically 75-90% less than using propane or Acetylene. The gasoline can be fed either from a pressurized tank (whose pressure can be hand-pumped or fed from a gas cylinder) or a non-pressurized tank, with the fuel being drawn into the torch by a venturi action created by the pressurized oxygen flow.

    Propane burner with a Bunsen flame Oxy-Acetylene for cutting through steel rails Flame of a gas and oil, in a dual burner. A gas burner is a device that produces a non-controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as the ambient air or supplied oxygen, and allowing for ignition and ...

  7. Weld purging - Wikipedia

    en.wikipedia.org/wiki/Weld_purging

    Sheet metal joints might be made on a seam welding machine where weld purging is carried out automatically as part of the machine design. Where sheet metal is formed into tanks or vessels prior to welding, the inside of the vessel can be purged with a flow of inert gas, however for larger sizes the cost of the gas and the time taken is unrealistic.

  8. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    The term cylinder in this context is sometimes confused with tank, the latter being an open-top or vented container that stores liquids under gravity, though the term scuba tank is commonly used to refer to a compressed gas cylinder used for breathing gas supply to an underwater breathing apparatus.
