The nozzle measures 3.219 inches in length with a 3\/8 inch (0.375 inch) bore and a 3\/4 inch OD. It features a three-piece construction: a nozzle housing cut and formed from copper alloy tubing, a nozzle insert machined from solid brass, and a nozzle insulator constructed from G7 silicone material. The 9\/16 inch-18 UNC-2B thread size matches conductor tube OD threads. Sold in packs of two. This nozzle is installed by qualified MIG welders and welding technicians as a consumable replacement part.\u003c\/p\u003e\n\u003cp\u003eThe 1230-1010 is suited for medium to heavy duty MIG welding environments where amperage demands reach up to 450 A. The silicone insulator provides the electrical isolation required between the nozzle and gas diffuser, eliminating the need for a separate insulator component. The recessed contact tip relationship of 0.125 to 0.156 inches is appropriate for applications requiring consistent shielding gas coverage and weld quality protection. The part number is roll-stamped on the outer surface, making identification straightforward during inventory and job-site use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-piece design: copper alloy housing, solid brass insert, and G7 silicone insulator — no additional insulator required\u003c\/li\u003e\n  \u003cli\u003eRated for welding applications up to 450 amps\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch bore (0.375 inch) with 3\/4 inch OD for standard gas diffuser compatibility\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch-18 UNC-2B internal thread matches conductor tube OD threads\u003c\/li\u003e\n  \u003cli\u003eRecessed contact tip relationship of 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on outer surface for easy field identification\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard gas diffusers and conductor tube assemblies compatible with the TWECO 23 Series Weldskill nozzle platform.

Disconnect and power down the welding machine completely before removing or installing nozzle consumables. Thread the nozzle onto the conductor tube assembly by hand until snug, taking care not to cross-thread the UNC-2B internal threads. Inspect the silicone insulator for cracking or damage at each consumable change to maintain proper electrical isolation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inch-18 UNC-2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecessed Contact Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: 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\u003eSeries\u003c\/strong\u003e: Weldskill 23\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: 1230-1010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344763158834,"sku":"1230-1010","price":27.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545906.jpg?v=1782042833","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1010-mig-welding-nozzle-3-8-inch-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
