Argon 4.8 from Linde is a high-purity inert gas designed for demanding welding applications, particularly for non-ferrous metals. Compared to standard grades, its higher purity ensures improved arc stability and superior weld quality.
Its low ionization potential enables easy arc ignition and stable arc performance without reacting with the base material. Argon effectively protects the weld pool from oxidation and contamination, which is critical for sensitive materials.
