The Ar/Mix optim izer is a gas-saving device that allows upgrading standard pressure regulators or clamping units in welding systems. By using this optimizer, it is possible to reduce gas consumption during welding, which contributes to lower operating costs and improved welding process efficiency. The device is designed for easy installation in existing systems. It has standard G3/8″ connection threads on both the inlet and outlet, allowing for seamless installation to pressure regulators or hook-up units. The Ar/Mix Optimizer is an effective way to save gas, improve productivity and reduce costs in welding systems.
