Welding Hoses & Regulators / Couplers

Welding gas hoses, regulators, and couplers are welding supplies such as hoses that connect gas cylinders and welders when welding, and equipment that is used to adjust the pressure from the cylinder to be constant. Since the pressure of the gas cylinder is not suitable for welding as it is, the pressure is adjusted using a regulator. There are various types of gas hoses depending on the length, inner diameter, gas used, etc. Some of them have connectors called couplers.
