Engineered for professional environments, this liner is compatible with a wide range of Tweco-style MIG guns, specifically the popular No. 1 and No. 2 series, as well as various Mini-MIG systems. It is sized to accommodate welding wires ranging from <strong>.035&#8243; to .045&#8243; (0.9mm to 1.2mm)<\/strong>, covering the most common diameters used in structural steel and general fabrication.<\/p>\n<p>Manufactured from high-quality zinc-plated spring steel, this conduit liner provides a smooth, low-friction path for the welding wire. The plating process enhances corrosion resistance, preventing rust buildup inside the cable assembly that can lead to increased drag and erratic feeding. With a total length of <strong>15 feet (4.5 meters)<\/strong>, it is ready to install in standard length guns but can be easily trimmed for 10-foot or 12-foot assemblies, making it a versatile stock item for maintenance departments.<\/p>\n<p>Consistent wire feeding is paramount for weld quality. A worn or kinked liner is a leading cause of arc instability, burn-back, and bird-nesting at the drive rolls. By replacing your liners at regular intervals with the Tweco 1420-1113, you ensure that your fleet operates at peak efficiency with minimal downtime. This product meets the rigorous demands of heavy manufacturing, automotive repair, and construction applications.<\/p>\n<h3>Key Technical Specifications<\/h3>\n<ul>\n<li><strong>Part Number:<\/strong> TWE1420-1113 (Replaces 42-3545-15)<\/li>\n<li><strong>Wire Compatibility:<\/strong> .035&#8243; &#8211; .045&#8243; Solid or Flux-Cored Wire<\/li>\n<li><strong>Length:<\/strong> 15 Feet (Trim to fit)<\/li>\n<li><strong>Material:<\/strong> Wound Spring Steel, Zinc Plated<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"Reliable Wire Feeding for Industrial Fabrication The Tweco 1420-1113 Universal Conduit Liner is a critical replacement component designed to restore and maintain the performance of your MIG welding equipment.
