The ESAB Steel MIG Liner (SKU: Q41511615) is a critical component designed to maintain the efficiency and reliability of MIG welding operations. Engineered for industrial environments, this liner is constructed from high-tensile wound steel, providing the necessary rigidity and flexibility to guide welding wire through the gun cable without kinking or collapsing. It is specifically sized for wire diameters between .045 inches and 1/16 inches (1.2mm to 1.6mm), making it suitable for medium to heavy fabrication tasks where larger wire sizes are utilized for higher deposition rates.
With a total length of 15 feet, this liner is compatible with standard 15-foot MIG gun assemblies. The internal surface of the liner is manufactured to strict tolerances to minimize friction coefficient against the moving wire. This reduction in friction is paramount for preventing feedability issues such as micro-arcing within the liner, erratic wire speeds, or complete jams known as "bird-nesting" at the drive rolls. The steel construction is optimized for use with hard wires, such as solid mild steel (ER70S-6) and flux-cored wires (E71T-1), offering superior wear resistance compared to polymer or Teflon liners which are reserved for softer alloys like aluminum.
Proper maintenance of the wire feeding path is essential for weld quality. Over time, liners accumulate metal shavings, dust, and drawing lubricants which can increase drag. Replacing the liner with this high-quality steel unit restores the gun's performance, ensuring that the wire is delivered to the contact tip with consistent speed and alignment. This component is an indispensable spare for maintenance, repair, and operations (MRO) departments managing welding fleets.
