CRONIGON 2He38 is a three-component mixture comprising 60% argon, 38% helium and 2% carbon dioxide. The addition of helium into the mixture accelerates welding speeds significantly relative to CRONIGON 2. This translates into vast productivity gains. High welding speeds also have the advantage of lower distortion, thus avoiding the need for costly rectification procedures. CRONIGON 2He38 produces welds with good fusion properties, coupled with low reinforcement and porosity characteristics. This extreme quality virtually eliminates the need for reworking or repairs.
This mixture is used for MAG welding across a wide variety of stainless steel alloys, proving particularly effective on thicker material sections. CRONIGON 2He38 is most effective in spray (free flight) and pulse transfer modes. The ideal operating range is between 6 and 15mm, although it can be used successfully outside this range.
