The WELLER T0051403399 is a lead-based alloy solder supplied on a 100-gram spool. It is formulated for use in precision soldering applications where controlled melt characteristics are required. The solder has a minimum melting temperature of 361.4 degrees F and a maximum melting temperature of 374 degrees F, providing a narrow working range suited to fine-pitch work. The wire diameter is 0.3 millimeters, making it well-suited for delicate joints on small components. Electricians, electronics technicians, and repair specialists working with sensitive assemblies will find this spool a reliable bench-stock item.
This solder is applicable across a wide range of industries and tasks including electrical and electronic repair, robotic soldering operations, automotive electronics, solar panel assembly, military and aerospace assemblies, and medical device manufacturing. The 100-gram spool size is practical for bench use and field repair kits alike. Its fine diameter supports clean, minimal-filler joints on close-tolerance work where excess material is a concern.
Designed for use in electrical, electronic, automotive, solar, military, aerospace, medical device, and general repair soldering applications as specified by the manufacturer.
This solder is applied by qualified electronics technicians and electricians using a calibrated soldering iron or automated soldering equipment. Always follow applicable safety protocols when working with lead-based materials, including proper ventilation and the use of personal protective equipment. Consult applicable industry standards and workplace safety regulations before use. Wash hands thoroughly after handling lead-containing solder.
