Abstract
The invention relates to a cutting torch provided to work with at least petroleum gas and oxygen gas, comprising a first unit (1), which in its turn comprises a mixing unit (3) to form a mixture of petroleum gas and oxygen gas, a torch head (4) with a torch nozzle (5) in the front portion of the first unit, means (12, 15 and 11, 14) for supplying petroleum gas and oxygen gas, respectively, to the mixing unit, at least a gas mixture conduit (7) for said gas mixture from the mixing unit (3) to the torch head (4), and at least an oxygen gas conduit (6), which is connectable to an oxygen gas supply conduit (13) to carry clean oxygen gas to the torch head. The invention is characterised in that the torch, in addition to petroleum gas and oxygen gas, is provided to work also with air and that it therefore comprises an air drum (2) surrounding said first unit (1), said air drum extending at a distance from said first unit along at least substantially its whole length, said air drum having a suction port (65) for air in its rear end, and an outlet (62) in its front end for ejecting air through said otulet in the form of an air flow in the longitudinal direction of the torch, said air flow surrounding the flame formed in front of the torch nozzle.
