Weldcut Equipment Industries offers Gas Mixers, Models KM 20-2 and KM 20-3, from Witt-Gasetechnik GmbH & Co KG, Germany. The company manufactures mixing, metering and control equipment as well as KM 2 analysing systems and safety equipment for all common gases. These are for gas mixing systems for 2 or 3 defined gases, designed for a variety of industrial applications for example, welding applications. Features: 1. Easy operation – a proportional mixing valve (-2) or three single mixing valves (-3), each with a control knob and %-scale, provide infinitely variable mixture settings; infinitely variable flow setting with scaled control knob; 2. High process reliability – independent of pressure fluctuations in the gas supply; independent of withdrawal fluctuations (in permitted range); and 3. Options – robust stainless steel housing. Other models, options and accessories are available on request.
