It accommodates wire diameters from 0.030 to 0.035 inches and is rated for welding current from 180 to 250 amps. At 25 feet in length, this liner fits full-length MIG gun assemblies and provides smooth, consistent wire feed from the wire feeder through the gun neck. The steel wound construction resists kinking and maintains shape under the heat and mechanical stress typical in production and fabrication welding environments. Welding technicians and industrial maintenance professionals install this liner as a routine consumable replacement to maintain feed performance.\u003c\/p\u003e\n\u003cp\u003eThis liner is suited for MIG welding applications in both shop fabrication and light industrial settings where steel wire is the primary filler material. It is compatible with TWECO R44 and R45 series conduit liner applications, as well as PULSEMASTER and PullMaster MIG gun platforms. Typical installations involve carbon steel and mild steel wire in short-circuit, spray, or pulse transfer welding processes. Replacing liners on a scheduled basis reduces wire feed resistance and minimizes bird-nesting at the drive rolls or gun neck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel wound construction for use with steel welding wire\u003c\/li\u003e\n  \u003cli\u003eWire diameter range: 0.030 to 0.035 inches\u003c\/li\u003e\n  \u003cli\u003e25-foot length suits full-length MIG gun assemblies\u003c\/li\u003e\n  \u003cli\u003eRated for 180 to 250 amps welding current\u003c\/li\u003e\n  \u003cli\u003eCompatible with R44, R45 series and PULSEMASTER and PullMaster 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 conduit liner applications and PULSEMASTER and PullMaster MIG guns.

Disconnect and de-energize the welder and wire feeder before removing or installing the liner. Feed the new liner through the gun cable from the feeder end, ensuring it seats fully at the gun neck connection. Trim the liner to the correct length per the gun manufacturer guidelines before securing end fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter Range\u003c\/strong\u003e: 0.030 to 0.035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiner Length\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 180 to 250 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: 1.38 pounds\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: 1420-1145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344587555122,"sku":"1420-1145","price":50.23,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546095.jpg?v=1782037124","url":"https:\/\/voomisupply.com\/products\/tweco-1420-1145-conduit-liner-0-030-0-035-in-25-ft-180-250a","provider":"Voomi Supply","version":"1.0","type":"link"}
