Weller T0051388199 Lead Free Solder Spool 100g

Product Description

The WELLER T0051388199 is a lead-free solder supplied on a 100-gram spool, formulated from a tin-based alloy for use in professional and precision soldering applications. With a melting range of 422.6 degrees F to 429.8 degrees F and a wire diameter of 0.3 millimeters, this solder is well suited for fine-pitch work where controlled heat and clean joints are critical. The narrow diameter makes it appropriate for circuit board rework, surface-mount component soldering, and other tasks where excess solder volume would cause bridging or pad damage. Licensed electricians, electronics technicians, and field service professionals use this product for both bench and field repair.

This solder is rated for a broad range of industries and application types, including electric and electronic assembly, repair work, robotic soldering systems, automotive electronics, solar panel manufacturing, aerospace, military, and medical device production. The lead-free alloy composition supports compliance with RoHS and similar regulations that restrict hazardous materials in electronic assemblies. The 100-gram spool size is practical for both bench technicians performing recurring repair work and professionals who need a compact supply for field kits.

Installation Notes

Soldering work on live or energized equipment must never be performed. Power down and discharge all capacitors before beginning any rework on electronic assemblies. Use a calibrated soldering iron or station capable of maintaining stable tip temperatures appropriate for the alloy melting range. Follow applicable workplace safety guidelines and ventilation requirements when working with solder flux vapors.
