Machined from solid 145 tellurium copper alloy bar stock, it delivers consistent dimensional stability and efficient heat dissipation at amperages up to 450 A. The bore measures 0.625 inches with an outer diameter of 1.07 inches and an overall length of 2.09 inches. The part number is roll-stamped on the outer surface for fast identification in the field. This is a two-piece nozzle design: the nozzle housing threads onto a separate nozzle insulator, which is sold separately.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for medium to heavy duty MIG welding environments where heat management and dimensional consistency are critical. The recessed contact tip relationship of 0.468 inches makes it appropriate for higher heat applications requiring longer electrical stick-out, or in situations where the nozzle may contact the work piece, such as tack, spot, and stitch welding. Licensed welding professionals and maintenance welders working in fabrication, structural, or industrial settings are the primary installers.

Always de-energize and power down the welding machine before replacing front-end consumables. Thread the nozzle insulator onto the conductor tube first, then thread the nozzle housing onto the insulator — do not overtighten by impact. Inspect the contact tip recess relationship after assembly to confirm proper stick-out for the intended welding process.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Tip Recess\u003c\/strong\u003e: 0.468 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 A\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: Two-piece\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: 0.17 pounds\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: 1240-1423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345156145458,"sku":"1240-1423","price":56.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546001.jpg?v=1782050724","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1423-mig-welding-nozzle-5-8-inch-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
