Built from 122 DHP copper alloy tubing, this nozzle features a 3\/8 inch (0.375 inch) bore and measures 3.25 inches in length. The contact tip relationship is tapered flush recess. A three-piece construction includes a formed copper alloy nozzle housing, a solid brass machined nozzle insert, and a G7 silicone nozzle insulator. The part number is roll-stamped on the outer surface for quick field identification. Sold as a 2-pack. Licensed welding professionals and MIG technicians install this nozzle as part of routine consumable replacement.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for heavy-duty MIG welding applications drawing up to 450 amps. It is designed for use with standard gas diffusers and is compatible with Tweco No. 3 MIG gun configurations. The nozzle insulator provides the electrical insulation required between the nozzle and gas diffuser, eliminating the need for a separate add-on insulator. The machined brass nozzle insert allows internal threads to be matched to conductor tube OD threads, ensuring a secure and repeatable fit in production and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch bore diameter rated for up to 450 amp MIG welding applications\u003c\/li\u003e\n\u003cli\u003eThree-piece design: 122 DHP copper alloy housing, solid brass insert, G7 silicone insulator\u003c\/li\u003e\n\u003cli\u003eNozzle insulator provides gas diffuser electrical isolation without a separate insulator component\u003c\/li\u003e\n\u003cli\u003eBrass nozzle insert machined to match conductor tube OD threads for consistent fit\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for fast identification during consumable changeouts\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Tweco No. 3 MIG guns rated up to 450 amps and standard gas diffuser configurations in the Tweco 23 Series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified welding technician or MIG gun service professional. Disconnect and de-energize the MIG gun and shut off shielding gas supply before replacing consumables. Thread the nozzle onto the conductor tube by hand until snug, taking care not to cross-thread the brass insert. Inspect the nozzle insulator for cracking or spatter buildup at each consumable change interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.375 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\u003eMaximum Amperage\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Tip Relationship\u003c\/strong\u003e: Tapered flush recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: 122 DHP copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert 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\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246056852\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: 1230-1302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344877060402,"sku":"1230-1302","price":59.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545912.jpg?v=1782044737","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1302-mig-welding-nozzle-3-8-in-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
