At 15 feet in length and rated for 300 to 450 amps, this liner provides consistent wire feed performance across demanding welding cycles. The steel wound construction maintains liner shape and resists kinking, which is critical for smooth wire travel through the gun cable. Welding technicians and fabricators rely on properly matched liners to reduce birdnesting, minimize wire feed resistance, and extend contact tip life. This liner is sold individually and weighs 1.15 pounds.\u003c\/p\u003e\n\u003cp\u003eThis liner is suited for heavy-duty MIG welding setups where steel wire is the primary consumable. It is built for use with TWECO R44 and R45 series liners as well as PULSEMASTER and PullMaster MIG guns. Typical applications include structural fabrication, manufacturing, and industrial MIG welding where higher amperage output and longer gun cables are required. It fits environments where consistent wire feed over a full-length cable run is essential to weld quality and operator efficiency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel wound construction supports smooth, consistent wire feed with steel welding wire\u003c\/li\u003e\n  \u003cli\u003eRated for 300 to 450 amps, suitable for high-amperage MIG welding applications\u003c\/li\u003e\n  \u003cli\u003e15-foot length accommodates standard full-length MIG gun cable assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch wire size compatibility for common steel welding wire diameters\u003c\/li\u003e\n  \u003cli\u003eCompatible with R44, R45, PULSEMASTER, and PullMaster TWECO MIG gun platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TWECO R44 and R45 series liners as well as PULSEMASTER and PullMaster MIG guns.

Trim the liner to the correct length per the gun manufacturer's specification before securing end fittings. Avoid forcing or kinking the liner during installation, as damage to the steel coil winding can cause wire feed irregularities. Inspect the liner periodically for debris buildup, which reduces feed efficiency and increases drive roll wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 5\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15 ft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 300 to 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Steel Wound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246288109\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TWECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1440-1142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51343125283122,"sku":"1440-1142","price":36.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546080.jpg?v=1782017398","url":"https:\/\/voomisupply.com\/products\/tweco-1440-1142-steel-wound-conduit-liner-5-64-in-15-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
