The "Flame Control Unit" is a flow control device that demonstrates stable flame and excellent reproducibility when added to a gas automatic brazing machine. By adopting a mass flow controller, the gas flow rate is digitally controlled. By numerically managing each condition, excellent stability and fast response can be achieved. It reduces the issues of flame instability caused by changes in supply pressure and the defect rate due to variations in gas flow rate when conditions change, which have been challenges for gas automatic brazing machines. 【Features】 ■ Logs gas flow rate and heating time during operation, enabling traceability in case of malfunctions. ■ Flow rate settings can be customized for each model, making changeover tasks easy. ■ The number of registered models can be tailored to customer requests (standard 20 models). ■ A mass flow controller is used for gas flow control. ■ Maintains a constant flow rate even with fluctuations in supply pressure. *For more details, please refer to the PDF document or feel free to contact us.
