Welding Couplers

A welding coupler is an instrument used for gas welding among welding products. In gas welding, oxygen and combustible gas are used for combustion, and the heat is used to melt and weld the metal. The material is mainly durable stainless steel. Welding couplers serve as gas hose joints, making it easy to connect various instruments and hoses. If the welding coupler is integrated with the gas hose, connection is easy. There is no risk of gas leaks as long as it has a structure that locks immediately after being pushed in. This is an indispensable product for gas welding factories.
