The basic difference of
a cutter "NORD" from other serially let out cutters consists
in an optimum design of mouthpieces and amalgamator of gases located
in the head of cutter, ensuring:
- injection action of a jet of oxygen acting
in the amalgamator under much by the large pressure, than combustible
gas;
- economical consumption of consumed gases;
- effectiveness of cutting on rather low, average and high pressure
of oxygen and combustible gas;
- reduction of working pressure of oxygen during the cutting
of metal by thickness from 3 up to 150 mm;
- high cleanliness of cutting;
- small width of cutting;
- high stability to return impacts;
- short time (2-4 сек) разогрева of metal in the beginning of
cutting.
Manufacturing cutters have three different lengths: 535 мм, 800
мм, 1000 мм и с тремя вариантами наклона головок: 0 град., 70 град.,
90 град. Комплектуются смесителями, мундштуками и гильзами в зависимости
от используемого горючего газа.
