Measuring 3\/8 inch in diameter and 0.85 inches in width, this nozzle installs at the front end of the MIG gun to direct shielding gas flow around the weld puddle. It is rated for use with guns operating in the 100-amp to 160-amp range. Each nozzle is marked with the part number or size directly on the component, simplifying identification in multi-consumable inventory. Welding technicians and fabricators working with Tweco-compatible equipment will find this a direct drop-in replacement.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for light- to medium-duty MIG welding applications in fabrication shops, maintenance and repair operations, and production environments where Tweco-style gun consumables are standard. It is appropriate for use in both single-pass and multi-pass welding scenarios within its rated amperage range. The self-insulated design reduces the risk of arc-out between the nozzle and contact tip holder, which is a common failure point under continuous duty conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-insulated construction reduces arc-out risk between nozzle and contact tip holder\u003c\/li\u003e\n\u003cli\u003eThreaded mount for secure, repeatable installation and removal\u003c\/li\u003e\n\u003cli\u003eRated for Tweco-style MIG guns from 100A to 160A\u003c\/li\u003e\n\u003cli\u003e3\/8 inch diameter bore for consistent shielding gas coverage\u003c\/li\u003e\n\u003cli\u003ePart number marked directly on nozzle for easy inventory identification\u003c\/li\u003e\n\u003cli\u003eOEM-quality interchangeability with Tweco and Tweco Weldskill Classic and Mini-MIG style guns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Tweco-style MIG guns rated 100A to 160A, including the Classic Weldskill and Mini-MIG platforms.

Always disconnect the MIG gun from the welder and release any residual wire tension before removing or installing nozzles. Use the appropriate nozzle wrench or pliers to seat the threaded nozzle fully without cross-threading. Inspect the contact tip and gas diffuser for wear at the same service interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Range\u003c\/strong\u003e: 100A to 160A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Self-insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Gun Style\u003c\/strong\u003e: Tweco-style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: XTRWELD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21-37\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XTRWELD","offers":[{"title":"Default Title","offer_id":51345185767730,"sku":"21-37","price":20.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546750.jpg?v=1782051254","url":"https:\/\/voomisupply.com\/products\/xtrweld-21-37-mig-nozzle-self-insulated-3-8-inch-tweco-style","provider":"Voomi Supply","version":"1.0","type":"link"}
