It features a 3\/8-inch (0.375-inch) bore and measures 3.219 inches in length with a 3\/4-inch OD. The nozzle threads onto the conductor tube assembly via a 9\/16-inch-18 UNC-2B thread and uses a recessed contact tip relationship of 0.125 to 0.156 inches. Constructed from 122 DHP copper alloy, this is a 3-piece design that eliminates the need for a separate external insulator. It is sold in packs of 2 and is intended for installation by professional welders and MIG welding technicians in industrial and fabrication environments.\u003c\/p\u003e\u003cp\u003eThis nozzle is designed for use with standard gas diffusers in heavy-duty MIG welding setups rated up to 450 amps. The recessed contact tip configuration is appropriate for higher-heat applications where longer electrical stick-out is required, or where the nozzle may contact the work piece during tack, spot, or stitch welding. The thread-on design mates directly with the conductor tube OD threads, making it a suitable fit for 23 Series TWECO-style torch front-end assemblies used in demanding fabrication and production welding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated for heavy-duty MIG welding applications up to 450 amps\u003c\/li\u003e\n\u003cli\u003e3\/8-inch bore with 3\/4-inch OD and 3.219-inch overall length\u003c\/li\u003e\n\u003cli\u003e3-piece design: nozzle housing cut and formed from 122 DHP copper alloy tubing, nozzle insert machined from solid brass, and nozzle insulator constructed of G7 silicone material\u003c\/li\u003e\n\u003cli\u003e9\/16-inch-18 UNC-2B thread-on attachment matches conductor tube OD threads directly\u003c\/li\u003e\n\u003cli\u003eRecessed tip relationship (0.125 to 0.156 inches) suited for longer stick-out and nozzle-to-work-piece contact scenarios\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for quick 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 a thread-on replacement nozzle for TWECO 23 Series torch assemblies using a standard gas diffuser and conductor tube configuration rated for heavy-duty welding up to 450 amps.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified MIG welding technician. Disconnect and de-energize the welding power source completely before replacing front-end consumables. Thread the nozzle onto the conductor tube assembly by hand until snug, taking care not to cross-thread the UNC-2B threads. Inspect the nozzle insulator and insert for wear or damage at each consumable change interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inches-18 UNC-2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecessed Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 450 amps\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\u003eNozzle Insulator 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: 0.19 pounds\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: 1230-1100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51342830469426,"sku":"1230-1100","price":81.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545927.jpg?v=1782007944","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1100-mig-welding-nozzle-3-8-inch-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
