Why is an argon regulator used in welding?
Using an Argon Regulator Regulators are used in welding to control the flow rate of gas from the tank to the welding hose. Regulating the flow of gas provides a higher quality weld, a safer work environment, and produces less waste. Connecting a hose directly to a gas tank instead of a regulator would cause an uncontrollable flow of gas.See all results for this questionWhy are argon mixtures used in arc welding?For the shielded metal arc welding process, an argon mixture is more commonly used in the form of blends to improve the metal transfer on the thicker materials, while providing a lower weld bead profile due to the deeper penetration.See all results for this questionWhat is Argon & Why is It Used for Welding?
