It features part number rolled stamped on the outer surface for easy identification. Nozzle with 9\/16\"-18 UNC-2B thread size and a recess contact tip relationship 0.125 - 0.156\" that is used where longer electrical stick-out is needed or when the nozzle touches the work place is made of 122 DHP copper alloy. It has a 3-piece design that includes a nozzle housing that is cut and formed from copper alloy tubing, a nozzle insert machined from a solid brass and nozzle insulator constructed of silicone material. It has nozzle insert that allows machining of internal threads in order to match the conductor tube OD threads. Nozzle offers electrical insulation required from the gas diffuser using the nozzle insulator and is sold as 2 per pack.\u003c\/span\u003e\u003c\/p\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNozzle Insert - machined from a solid brass allow and machining the internal threads to match the conductor tube OD threads\u003c\/li\u003e\n\u003cli\u003eThread-on\u003c\/li\u003e\n\u003cli\u003eNozzle insulator - made from g7 silicone material, providing the electrical insulation needed from the gas diffuser\u003c\/li\u003e\n\u003cli\u003e3-piece nozzle design, includes: Nozzle Housing - Cut and Formed from 122 DHP copper alloy tubing\u003c\/li\u003e\n\u003cli\u003eRecessed Tips are generally used for higher heat applications where longer electrical stick-out is required, or in cases where the nozzle may touch the work piece (tack, spot, and stitch)\u003c\/li\u003e\n\u003cli\u003eFlush Tips are generally used where a shorter electrical stick-out is used sometimes resulting in shorter\/tighter arc lengths, This brings the tip closer to the work piece\u003c\/li\u003e\n\u003cli\u003eHowever the down side to this is the chance of arcing the tip to the work piece, which could damage front end parts resulting in downtime needed to replace\u003c\/li\u003e\n\u003cli\u003eEasy identification - part no rolled stamped on the outside surface\u003c\/li\u003e\n\u003cli\u003eProtruding Tips are generally used when welding open root pipe or any joint that requires the welder to get into a tight weld joint\u003c\/li\u003e\n\u003cli\u003e3-piece design - does not require an additional insulator\u003c\/li\u003e\n\u003cli\u003e1\/8\" to 5\/32\" Tip Recess\u003c\/li\u003e\n\u003cli\u003eNozzle housing - cut and formed from 122 dhp copper alloy tubing\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eUsed in heavy duty welding application up to 450 Amp\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 450 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Length:\u003c\/strong\u003e 3.219 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Bore:\u003c\/strong\u003e 0.625 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size:\u003c\/strong\u003e 5\/32 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 9\/16-18 UNC-2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical Size:\u003c\/strong\u003e 0.9 x 3.2 x 0.9 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nozzle Relationship:\u003c\/strong\u003e Recessed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 122 DHP Copper Alloy, Brass, Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Mexico\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 23 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMIG Gun Model:\u003c\/strong\u003e Tweco  | Tweco  No. 3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tweco","offers":[{"title":"Default Title","offer_id":47733559820475,"sku":"EB12301220","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/5763\/0651\/files\/a33396c1619adc17b501406894d076c38e1791f1-large.png?v=1784588283","url":"https:\/\/wiscocatalog.myshopify.com\/products\/eb12301220-tweco-12301220-nozzle-3219-in-0625-in-bore-532-in-recessed-450-a-23-series","provider":"Wisco Catalog","version":"1.0","type":"link"}
