The kit includes an oxygen regulator with a wide inlet range and an acetylene regulator suited to lower working pressures, and the most compelling reason to buy is the practical combination of correct CGA tank fittings and hose outlets that match twin welding hoses, making installation fast when fittings are compatible.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrect tank fittings:\u003c\/strong\u003e Oxygen uses CGA-540 and acetylene uses CGA-510, which ensures the regulators attach to the matching tanks used for most oxy-acetylene setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose outlet thread:\u003c\/strong\u003e The 9\/16'-18 outlet thread fits 1\/4 in B fittings on twin welding hoses so you can connect standard torch lines without adaptors when sizes match.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure control:\u003c\/strong\u003e The oxygen regulator offers delivery up to 4000 PSI and adjustable output to 200 PSI, giving broad range for cutting and preheat tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcetylene range:\u003c\/strong\u003e The acetylene regulator delivers from 0-400 PSI inlet with an output adjustable to 30 PSI, suitable for typical welding flame settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded accessories:\u003c\/strong\u003e The set ships with both regulators, T-handle and outlet hose connector nut so the basic hardware needed for setup is provided.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis pair is best for DIY welders, metal hobbyists and small shops that perform medium duty gas welding and cutting and already own or will purchase tanks and twin hoses with the listed fittings.
