The MDX™ MIG Gun Liner from Miller Electric is expertly designed for precision and efficiency in welding applications, accommodating wire sizes from 0.023" to 0.030". This innovative liner simplifies the replacement process, allowing for accurate trimming without the need for measuring—just load and lock it from the front of the gun, then trim flush with the power pin cap at the back. By ensuring the contact tip is perfectly aligned with the liner lock, it creates a seamless wire-feed path that significantly minimizes common issues such as burnbacks, bird-nesting, and erratic arcs, making it an essential component for achieving high-quality welds. With a length of 10 feet, this liner is a reliable choice for both professional welders and DIY enthusiasts looking to enhance their welding performance.
