CONCOA introduces a new blender that enables users to create custom-blended gas mixtures on site for 
GTAW (TIG) and GMAW (MIG) industrial welding applications. Designed to increase productivity by eliminating time-consuming cylinder handling, the BlendMaster 657 Series provides 0 to 25% blend adjustability for two-component gases. Blending pure argon and carbon dioxide gases, the machine enhances quality by maintaining a +/- 1.5% accuracy. This technology allows for full flow regardless of the mix or blend ratio and a pressure equalization system minimizes inlet pressure fluctuations to stabilize the mix, broadening the inlet pressure range difference between the major and minor component gases. The low inlet pressure range allows for accurate mixing even while supply sources are filled. Additionally, an optional low-pressure remote alarm can be integrated with other building systems via contact interface to provide a higher level of systems integration.
