FIELD: technological processes.
SUBSTANCE: invention can be used for thermal cutting of metals and nonmetals under water and on surface in ambient conditions. System of hoses and pipelines of oxygen system main line 2 connects independent source of oxygen 1 with electrode 4 holder 3. Ignition device 5 is made in form of independent moisture proof power unit, connected by wiring 6 with electrode 4. Oxygen system has controlled oxygen reducer 8 and is equipped with flow control valve 9, operating mode tap 10 and blowdown valve 11 connected to oxygen system main line 2. Oxygen system is also equipped with quick-detachable connection assembly 12 for supply of oxygen from surface, check valves 13 and 14 and controlled check valve 15. Control panel 16 has mimic oxygen system and control members of flow control valve 9, operation mode tap 10 and blowdown valve 11.
EFFECT: device provides high safety when conducting underwater exothermic cutting and ease of use.
