The logas-2b copper degasser is a tool used in the metal casting process to remove gases from molten copper, including hydrogen, nitrogen, and carbon dioxide. These gases can contribute to flaws in the end product, such as porosity and brittleness, by being present in the molten copper. It operates by forcing a stream of inert gas through the liquid copper, often argon or nitrogen, causing the gases to bubble out and escape. The logas-2b copper degasser is made to be simple to operate and keep up with. Its straightforward control panel features digital displays for temperature, gas flow rate, and other significant parameters.
