    Oxygen mainly plays a role of combustion support, it can increase the speed of cutting and the thickness of cutting. Oxygen is suitable for thick metal cutting, high speed cutting and extremely thin metal cutting. For example, such as some thicker carbon steel plates, oxygen can be used. When cutting metals of different materials and thickness, choosing the suitable gas can help to shorten the cutting time and improve the cutting effect.

  • 3.nitron

    When cut stainless steel, aluminum metal plate, most of our customers choose to use nitrogen. When use Nitrogen cut stainless steel, the edge will be light.
