0700200177 - ESAB 10M Steel MIG Liner for 0.040-0.045 Wire

Precision Wire Delivery for Industrial Applications

The ESAB 0700200177 Steel Liner is a premium replacement component engineered to facilitate the smooth transfer of welding wire through MIG guns and conduit systems. Specifically designed to accommodate wire diameters between 1.0mm and 1.2mm (0.040" to 0.045"), this liner is an essential element for maintaining arc stability and weld quality. The liner features a robust spiral-wound steel construction, which provides the necessary rigidity to prevent collapsing while maintaining enough flexibility to navigate the curvature of welding cables without kinking.

With an exceptional length of 10 meters (approximately 32.8 feet), this liner is tailored for long-reach applications, such as push-pull torch systems, automated welding cells, or extended conduit runs where standard 3-5 meter liners fall short. The high-quality steel material is optimized for use with solid mild steel and flux-cored wires, offering excellent resistance to the abrasive nature of these consumables. By minimizing internal friction, the liner ensures that the wire feed motor transmits force efficiently to the contact tip, reducing the load on the drive rolls and preventing slippage.

Proper liner maintenance is critical for any welding operation. Over time, liners can accumulate metal shavings, dust, and lubricant residue, leading to erratic feeding, micro-arcing inside the contact tip, and eventual burn-back. Replacing your worn liner with this genuine ESAB part restores the mechanical integrity of your wire delivery system. The 0700200177 is manufactured to tight tolerances, ensuring a precise fit within compatible ESAB torch assemblies and conduit connectors. Whether used in heavy fabrication, shipyards, or structural steel environments, this liner provides the reliability professional welders demand.

Installation is straightforward for qualified personnel. The liner can be trimmed to the exact length required for your specific setup, ensuring optimal support for the wire right up to the gas diffuser or contact tip. By choosing genuine ESAB parts, operators ensure that their equipment continues to perform at factory specifications, safeguarding both productivity and weld integrity.
