Equipped with gas operating table, independent adjustment of ionic gas and protective gas, improve cutting precision, and adapt to a variety of gas cutting processes of high-quality cutting
Derived from the core of fine plasma cutting machine, the cutting quality is better than that of ordinary plasma cutting machine
The independent high frequency arcing controller reduces the interference of high frequency to the CNC and robot system, shortens the torch cable, improves the cooling effect of the torch, and improves the reliability of arcing
Tailor-made torch cooling system, equipped with large flow, high lift pump and high power cooling structure, effectively extend the service life of torch consumables
Rigorous gas path control logic, especially suitable for "oxygen ion gas/air protection gas" cutting carbon steel, compared to ordinary air plasma cutting quality
With analog and RS485 digital communication interface, easy to expand the function, easy to match with a variety of intelligent numerical control systems
It has rich two level menu functions and monitoring and control functions.
Product application
Mainly used for carbon steel, alloy steel, stainless steel, aluminum and other metal materials cutting.
Widely used in pressure vessels, hydropower, metallurgy, chemical industry, shipbuilding, special and commercial vehicle modification, steel structure construction, parts processing and other medium and thick plate metal cutting industries.
