Plasma Gas Mixture Plasma gas mixture refers to the combination of gases used to create the plasma arc in plasma cutting and welding processes. The plasma gas mixture typically consists of an inert gas, such as argon or nitrogen, along with a reactive gas, such as oxygen or hydrogen. The inert gas serves to stabilize the plasma arc and protect the cutting or welding area from atmospheric contamination, while the reactive gas enhances the cutting action by reacting with the material being processed. The composition of the plasma gas mixture can be adjusted based on the material being cut, desired cut quality, and process requirements. |
