It accommodates wire diameters from 0.035 to 0.045 inches and supports amperage ratings from 300 to 450 amps, making it suited for mid- to high-amperage production welding. At 25 feet in length, this liner routes wire smoothly through MIG gun cables, reducing friction and minimizing feed issues that cause arc instability. Welding technicians and fabricators working with steel wire on industrial MIG setups rely on properly fitted conduit liners to maintain consistent wire delivery and weld quality.\u003c\/p\u003e\n\u003cp\u003eThis liner is intended for steel welding wire applications in industrial and fabrication environments. It is compatible with the TWECO R44 and R45 series liners, as well as PULSEMASTER and PullMaster MIG guns. Typical installations include heavy-duty MIG setups in manufacturing, structural fabrication, and repair shops where steel wire is the primary consumable. The 25-foot length suits standard industrial gun cable assemblies used in fixed and semi-automated welding stations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel wound construction optimized for steel welding wire compatibility\u003c\/li\u003e\n  \u003cli\u003eWire diameter range of 0.035 to 0.045 inches for versatile wire sizing\u003c\/li\u003e\n  \u003cli\u003e25-foot length fits standard industrial MIG gun cable assemblies\u003c\/li\u003e\n  \u003cli\u003eSupports 300 to 450 amp welding applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with TWECO R44, R45, PULSEMASTER, and PullMaster MIG gun series\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 using steel welding wire in the 0.035 to 0.045 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified welding technician with the MIG welder powered down and the gun cable disconnected from the wire feeder before liner replacement. Feed the liner through the cable from the gun end, trim to the appropriate length per the gun manufacturer specification, and secure the retaining fitting before threading wire. Avoid kinking the liner during installation, as deformation restricts wire feed and accelerates wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter Range\u003c\/strong\u003e: 0.035 to 0.045 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Range\u003c\/strong\u003e: 300 to 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel Wound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: 1440-1145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51343964111154,"sku":"1440-1145","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546084.jpg?v=1782026088","url":"https:\/\/voomisupply.com\/products\/tweco-1440-1145-steel-wound-conduit-liner-25-ft-mig","provider":"Voomi Supply","version":"1.0","type":"link"}
