E7A5011 - 10ft Steel MIG Liner for .030-.045 Wire

High-Performance Steel Liner for MIG Welding Torches

The Nu-Tec E7A5011 is a premium steel replacement liner designed to restore optimal performance to your MIG welding system. Engineered for durability and precision, this liner is compatible with a wide range of steel and flux-cored welding wires, specifically accommodating diameters from .030" to .047" (0.8mm to 1.2mm). The liner measures 3 meters (approximately 10 feet) in length, making it a perfect fit for standard 10-foot MIG gun assemblies commonly used in industrial and fabrication environments.

Constructed from high-tensile spiral-wound steel, this liner provides a rigid yet flexible conduit that protects the welding wire as it travels from the feeder to the contact tip. The internal surface is finished to minimize friction, ensuring consistent wire feed speeds and preventing the erratic arc behavior often caused by drag or slipping drive rolls. This specific liner is often compatible with Binzel-style torches and other European-style MIG guns, offering a reliable aftermarket solution for maintenance and repair operations.

Proper liner maintenance is critical for weld quality. Over time, liners can accumulate copper dust, dirt, and debris, leading to increased friction and potential wire jamming (birdnesting). Replacing your liner with the E7A5011 ensures that your wire feeds smoothly, reducing downtime and improving the overall stability of the welding arc. This component is essential for welders working with mild steel or flux-cored wires who require reliable, uninterrupted feeding for high-quality weld deposits.
