The ESAB 0558002140 MIG Liner is a critical replacement component designed specifically for the ESAB Gun Master (GM) series of welding guns. Engineered to handle the rigorous demands of heavy industrial fabrication, this liner is compatible with both the GM250 and GM400 MIG guns. It is precision-wound to accommodate large diameter welding wires ranging from 5/64 inch to 3/32 inch, making it an essential accessory for structural steel, heavy equipment repair, and other high-deposition welding tasks.
Wire feeding issues are among the most common causes of downtime in welding operations. A worn or clogged liner can lead to erratic arc starts, wire chatter, and the frustrating "bird-nesting" of wire at the drive rolls. This ESAB liner features a robust steel spiral construction that provides the necessary rigidity to guide heavy wires smoothly through the cable assembly while maintaining enough flexibility to navigate the gun's curvature. With a generous 25-foot length, this liner is ideal for extended-reach setups where operators need to move freely around large workpieces without moving the wire feeder.
Proper maintenance of your MIG gun's front-end consumables is vital for weld quality. The liner acts as the conduit for the welding wire, protecting it from the outer cable and ensuring it remains centered for optimal electrical contact at the tip. Over time, liners accumulate copper dust, dirt, and debris which increases friction. Replacing your liner with this genuine ESAB part ensures that your GM250 or GM400 gun operates at peak efficiency, delivering the consistent wire speed required for high-quality welds.
