The Lincoln Electric patented HyperFill® twin-wire solution was developed to revolutionize heavy fabrication productivity. Designed for semiautomatic and robotic applications, HyperFill redefines high deposition welding – allowing you to make larger welds, faster and more easily. The HyperFill HD Gas Diffuser has been newly designed with a dual-cam feature that improves electrical transfer, is easier to torque into place, and is ideal for high deposition and high heat GMAW applications.
