Rated up to 450 amps, it features a 0.5 inch bore and measures 3.25 inches in length with a 0.875 inch outer diameter. The three-piece construction eliminates the need for a separate insulator, combining a nozzle housing formed from 122 DHP copper alloy tubing, a solid brass machined insert, and a G7 silicone insulator. The part number is roll-stamped on the exterior for fast identification during service. Sold as a pack of two.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for medium and heavy duty MIG welding operations where amperage demands reach up to 450 A. The recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for higher heat applications requiring longer electrical stick-out, as well as tack, spot, and stitch welding scenarios where the nozzle may contact the workpiece. The slip-on design allows the nozzle to slide over the metal spring on the gas diffuser, making changeovers straightforward in production and field welding environments. Licensed welders and fabricators working with compatible Tweco-style front-end consumables will find the two-pack quantity practical for keeping spares on hand.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated up to 450 amps for medium and heavy duty MIG welding\u003c\/li\u003e\n\u003cli\u003eThree-piece design requires no additional insulator\u003c\/li\u003e\n\u003cli\u003eNozzle housing cut and formed from 122 DHP copper alloy tubing for conductivity and durability\u003c\/li\u003e\n\u003cli\u003eNozzle insert machined from solid brass and crimped in place to secure fit over gas diffuser spring\u003c\/li\u003e\n\u003cli\u003eG7 silicone insulator provides electrical isolation from the gas diffuser\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 for use with standard gas diffusers in Tweco-style MIG welding torch front-end assemblies.

Slip the nozzle over the gas diffuser spring until fully seated before resuming operation. Inspect the nozzle insert and insulator for wear or spatter buildup at regular intervals, as degraded insulation can cause unintended arcing. Follow applicable AWS and equipment manufacturer guidelines for front-end consumable maintenance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.875 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\u003eMaximum Amperage\u003c\/strong\u003e: 450 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Housing Material\u003c\/strong\u003e: 122 DHP Copper Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Insert Material\u003c\/strong\u003e: Solid Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material\u003c\/strong\u003e: G7 Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246005010\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: 1260-1607\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347312181554,"sku":"1260-1607","price":36.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546024.jpg?v=1782101176","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1607-slip-on-mig-nozzle-450a-0-5-in-bore-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
