FIELD: process engineering.
SUBSTANCE: invention relates to portable device for thermal processing of metal materials to be used for cutting metal structures. Proposed device comprises back-pack, two containers for liquid fuel, container for oxygen, oxygen reduction valve, gas-liquid cutter and liquid fuel and oxygen feed hoses. Said hoses are connected to cutter and said containers. Kerosene or diesel fuel is used as combustible material. Liquid fuel container top parts are interconnected by tube to maintain constant pressure in both containers. Liquid fuel container bottom parts are interconnected by tube to maintain equal fuel level therein. Central parts of containers are interconnected by two metal plates. Said metal plates, said containers and said tubes make carcass for aforesaid back-packs, hose winders and containers with oxygen.
EFFECT: improved operating performances and higher safety.
