Features: Double safety lock: The patented safety lock design system prevents connections being disconnected from socket due to unexpected external forces and vibrations during operation. The design feature allows applications not only in general welding, gas-cutting in-door application but also in severe operating conditions in outdoor applications. Double Sealing Construction: The innovative patented double safety sealing construction eliminates gas leakage while connecting plug into socket Backflow Prevention and Anti-inflammatory Plug (PAC/ PTC): The design construction has inbuilt safety features that operates stop check valve when reverse gas flow is generated due to any trouble at welding, cutting side of the machine. This prevents gas mixing. Quality and Function: The components are manufactured with precision quality control. The components are 100% tested for leakage detection with advance technology equipments. Built-in quality and design features ensure high safety standards, excellent operation performance and durability. Design allows ample gas flow to meet application requirements.
