The oxygen-fuel cutting torch has a head to one face of which three gas supply conduits communicating with three longitudinal ducts are connected and to the other face of which by means of a nut an outer tip is connected. An inner tip is disposed coaxially with a second duct and the outer tip. The inner tip defines with the wall of said second duct an annular chamber communicating with the second duct and a longitudinal annular metering passageway which communicates with said annular chamber and an annular channel between the tips. Between the faces of the head and the outer tip, there are provided an annular seal and a transverse annular metering passageway communicating with said annular channel between the tips and with a second annular chamber which is connected to the third longitudinal duct in the head. The present oxygen-fuel cutting torch is simpler in construction than known similar cutting torches.

Disclosure is made of a machine in which, according to the invention, a tool carriage is mounted on the crossbeam for rotation in a plane perpendicular to the axis of the crossbeam. A rod rigidly coupled with a cutting torch is mounted on the tool carriage. This rod is fixed on the crossbeam for rotation and longitudinal reciprocation in a plane parallel to the axis of the crossbeam.
