Before changing or seating a cutting tip, shut off all gas supply valves at both the torch handle and the cylinder regulators and bleed the lines. Thread the tip into the cutting attachment by hand first, then snug with the appropriate tip wrench — do not overtighten brass fittings. Inspect tip seating surfaces for debris or damage before lighting and verify all connections are leak-free using approved leak-detection solution.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Number\u003c\/strong\u003e: 3NX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Gas\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23271711\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: LINCOLN ELECTRIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1501250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LINCOLN ELECTRIC","offers":[{"title":"Default Title","offer_id":51559079280946,"sku":"1501250","price":34.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fab2defb49b6db10ed464daee7bace4.jpg?v=1786426804","url":"https:\/\/voomisupply.com\/products\/lincoln-electric-1501250-cutting-tip-3nx-natural-gas","provider":"Voomi Supply","version":"1.0","type":"link"}
