With a melting range of 422.6 degrees F to 429.8 degrees F and a wire diameter of 1.2 mm, this solder delivers consistent flow and joint integrity on a wide variety of connection types. The spool format supports both hand soldering and automated solder robot processes, making it practical for bench technicians and production environments alike. Licensed electricians, electronics technicians, and repair professionals are the primary users of this product.\u003c\/p\u003e\u003cp\u003eThis lead-free solder alloy is suited for residential and commercial electrical work, electronic component assembly, and specialty soldering in demanding sectors including military, aerospace, medical device manufacturing, solar installations, and automotive electronics. The 500 g spool size supports extended work sessions without frequent material changeovers, making it a practical choice for shops and field technicians handling volume repair or assembly tasks. Its lead-free formulation aligns with RoHS-compliant and environmentally conscious project requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free alloy formulation suitable for RoHS-compliant and regulated applications\u003c\/li\u003e\n\u003cli\u003eMelting range of 422.6 degrees F to 429.8 degrees F for predictable reflow behavior\u003c\/li\u003e\n\u003cli\u003e1.2 mm wire diameter compatible with standard soldering irons and solder robot feeders\u003c\/li\u003e\n\u003cli\u003e500 g spool format reduces changeover frequency during extended soldering sessions\u003c\/li\u003e\n\u003cli\u003eBroad application range including electrical, electronic, aerospace, solar, automotive, and medical device work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard soldering irons, soldering stations, and automated solder robot equipment that accept 1.2 mm diameter solder wire across electrical and electronic assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis solder is intended for use by qualified electricians, electronics technicians, and trade professionals familiar with proper soldering technique and safety practices. Always power down and de-energize circuits completely before soldering any live electrical components. Work in a well-ventilated area and use appropriate fume extraction equipment, as solder flux vapors require respiratory precautions even with lead-free alloys. Follow applicable codes including NEC guidelines when soldering electrical connections in listed assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolder Type\u003c\/strong\u003e: Lead Free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Spool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 500 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 1.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Melting Temperature\u003c\/strong\u003e: 422.6 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Melting Temperature\u003c\/strong\u003e: 429.8 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23271806\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WELLER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T0051386799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WELLER","offers":[{"title":"Default Title","offer_id":51559691092274,"sku":"T0051386799","price":238.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/581dd3f7b19f76b3cc1c5e82543570ab.jpg?v=1786438278","url":"https:\/\/voomisupply.com\/products\/weller-t0051386799-lead-free-solder-alloy-spool-500-g","provider":"Voomi Supply","version":"1.0","type":"link"}
