FIELD: machine building.
SUBSTANCE: device comprises flux feeder (1), cutting torch (2) and process gases mains for cutting oxygen (18) and nitrogen (16), block (4) of reverse cold cryogenic gasifiers of liquid oxygen, block (8) of reverse cryogenic gasifiers of liquid methane, block (6) of reverse cold cryogenic gasifiers of liquid nitrogen. The cryogenic adsorptive accumulators of oxygen (10) and methane (13) with automatic vent valves (11) and (12) are connected to outputs of the blocks (4) and (8) of reverse cryogenic cold gasifiers.
EFFECT: improvement of profitability of flux-oxygen cutting and improvement of fire and explosion safety.
