Designed for: machine parting cutting of low-carbon steel 300 to 800 mm thick (ingots, forged pieces, etc.).
It has been successfully used at such enterprises as PJSC “Energomashspetsstal” and PJSC “ArcelorMittal Kryviy Rih”.
The cutting torch’s most distinguishing feature is external gas mixing that happens outside the nozzle which makes backfires impossible.
Design features: separate feed channels for cutting oxygen and preheating oxygen; gas consumption adjustment via the gas-cutting machine control panel.
Used gas fuel: natural gas (methane).
The delivery set contains nozzle No. 800 (order No. 511.001.00). As per customer’s order the cutting torch can be supplied with nozzles No. 300 (order No. 511.001.01) and No. 500 (order No. 511.001.02).
