QT200 Series Gas Mixer
The QT200 Series gas mixer is designed to supply shielding gas to one or two welding machines. It uses mass flow measurement in place of conventional variable-area flowmeters. Inlet and outlet pressure sensors support real-time monitoring, while flow limit alarms, switching alarm outputs, and data logging support process analysis and traceability.
