Machined from a solid 145 tellurium copper alloy bar, the nozzle delivers consistent dimensional stability and efficient heat dissipation across demanding weld cycles. The bore measures 3\/4 inch with an outside diameter of 1.057 inches and a nozzle length of 1.46 inches. Rated up to 600 amps, it is suited for applications where thermal load is high. The recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for longer electrical stick-out situations or when the nozzle may contact the workpiece. Sold in a 2-piece pack. Licensed welding technicians and MIG welding professionals install this nozzle as a front-end consumable replacement.\u003c\/p\u003e\u003cp\u003eThis nozzle is designed for medium to heavy duty MIG welding applications rated up to 600 amps. The recessed tip geometry is particularly suited for higher heat welding situations, including tack, spot, and stitch welding, as well as scenarios where the nozzle may contact the workpiece. The two-piece design separates the nozzle housing from the nozzle insulator, allowing each component to be replaced independently. The nozzle insulator threads onto the conductor tube while the nozzle housing threads onto the insulator. This design reduces overall consumable replacement cost during high-volume production or repair welding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMachined from solid 145 tellurium copper alloy bar for consistent dimensional stability and heat dissipation\u003c\/li\u003e\n\u003cli\u003eTwo-piece design: nozzle housing and nozzle insulator are separate, replaceable components\u003c\/li\u003e\n\u003cli\u003eRecessed contact tip relationship of 0.125 to 0.156 inches suits higher heat and longer stick-out applications\u003c\/li\u003e\n\u003cli\u003eRated up to 600 amps for medium to heavy duty MIG welding\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior surface for easy field identification\u003c\/li\u003e\n\u003cli\u003eSold as 2 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for TWECO 26CT series MIG torch setups using a standard gas diffuser configuration.

Ensure the welding machine is powered down and the torch has cooled completely before removing or installing front-end consumables. The nozzle housing threads onto the nozzle insulator, which in turn threads onto the conductor tube — do not overtighten, as this may damage the insulator. Follow the torch manufacturer's assembly sequence to ensure proper insulation and gas shielding coverage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 1.46 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.057 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Tip Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 600 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 145 tellurium copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e: 2-piece (nozzle housing and nozzle insulator)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246058948\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1260-1430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344186802482,"sku":"1260-1430","price":66.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546028.jpg?v=1782031126","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1430-mig-nozzle-3-4-in-bore-600a-coarse-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
