Versatile Gas Compatibility: Equipped with a standard CGA-580 connector, this regulator seamlessly attaches to both and CO2 tanks. For CO2 tank compatibility, a separate CGA-320 adapter is required, enhancing its utility across gas types for diverse welding needs. Flexible Connection Options: This regulator features a multi-connector design including a 9/16-inch external thread, a 5/8-inch internal thread, and a 1/4-inch hose barb. These options provide adaptability for different setups, ensuring a secure and efficient connection for all your welding projects. Advanced Filtration System: The regulator's CGA-580 inlet incorporates a sophisticated filtration mechanism that prevents impurities and particles from compromising the gauge system. This feature not only extends the lifespan of the gauge but also maintains the gas purity, crucial for high-quality welding results. Precise and Construction: Crafted from robust brass, the regulator boasts a dual gauge display with a high precision readout. It supports an inlet pressure range of 0-4000 PSI, with specific output ranges for (0-30 ) and CO2 (0-20 ), ensuring optimal performance and reliability. Safe and Efficient Operation: To maximum safety and effectiveness, connect the regulator to your gas cylinder before opening the valve. Attach and adjust the T-handle slowly to achieve the desired gas pressure, preventing any potential gas leakage and promoting a secure welding environment.
