Weller T0051387099 Lead Free Solder Spool 500 G

Product Description

The WELLER T0051387099 is a lead-free solder supplied on a 500 g spool, formulated from an alloy blend designed for professional soldering applications. With a melting range of 422.6 degrees F to 429.8 degrees F and a wire diameter of 0.5 mm, this solder is suited for fine-pitch work and general-purpose joints alike. The lead-free composition supports compliance with RoHS and similar environmental directives. It is installed by electronics technicians, HVAC controls specialists, electricians, and field service professionals who need a reliable, consistent solder for both bench and in-field repair work.

This solder is appropriate for a wide range of industries and applications, including electric and electronic assembly, circuit board repair, robotic soldering systems, automotive electronics, solar panel wiring, aerospace assemblies, medical device manufacturing, and military-grade repairs. The 500 g spool size makes it practical for both shop benches and mobile service kits. It is well suited to residential and commercial service environments where lead-free materials are required by code or specification.

Installation Notes

This solder is applied by electronics technicians and qualified service professionals using calibrated soldering irons or robotic soldering equipment. Set iron tip temperature to match the alloy melting range before application, and allow joints to cool undisturbed to prevent cold solder connections. Work in a well-ventilated area, as flux fumes are generated during soldering regardless of lead content. Always power down and discharge any capacitors in electronic assemblies before beginning solder work.
