The Argo-Naught and Ar-Gone Weld Gas Analyzers accurately monitor oxygen levels while using inert gas to purge stainless steel, titanium and other reactive metal. The Argo-Naught and Ar-Gone Weld Gas Analyzers measure oxygen content in the weld chamber down to 0.1% (1000 ppm). The Argo-Naught and Ar-Gone Weld Gas Analyzers help save on argon gas consumption and will increase the welder’s production rate. The Argo-Naught and Ar-Gone Weld Gas Analyzers quickly identify any oxygen level drawn into the weld chamber that is being shielded with inert gas. The Argo-Naught and Ar-Gone Weld Gas Analyzers will save the weld root by showing the fabricator if the levels rise to an unacceptable level.
