Mixed Gas: Mixed gases are specially formulated combinations of gases tailored for specific applications, particularly in industries like welding, diving, and manufacturing. These mixtures optimize properties like flame temperature, stability, and reactivity, enhancing performance and safety. For example, in welding, a mix of argon and CO₂ improves arc stability and penetration, while in diving, specific oxygen-nitrogen mixes reduce the risk of decompression sickness. Each blend is carefully balanced to meet the unique requirements of the application, providing versatility and precision in industrial and technical processes.
