Weller T0051388399 Lead Free Solder Alloy Spool 100g

Product Description

The WELLER T0051388399 is a lead free solder supplied on a 100g spool, formulated from a metal alloy designed for clean, reliable joints across a wide range of soldering applications. It carries a melting range of 422.6 degrees F to 429.8 degrees F, giving technicians a narrow working window suited to controlled, precise soldering work. The 0.3mm diameter wire feeds smoothly through both manual irons and automated solder robots. This solder complies with lead free requirements, making it appropriate for projects where RoHS-aligned materials are specified or required by contract.

This solder is suited for residential and commercial electronics repair, electrical assembly, automotive wiring harness work, solar panel connections, aerospace assembly, military applications, medical device manufacturing, and general home projects. Its small spool size and fine diameter make it practical for bench technicians and field service work alike. The lead free alloy composition supports applications where material traceability and compliance documentation are part of the job scope.

Installation Notes

Soldering work on energized circuits or live equipment should never be performed without first powering down and isolating the circuit. Licensed electricians and electronics technicians should follow applicable NEC guidelines and manufacturer soldering procedures. Use appropriate ventilation when soldering, as flux fumes require extraction regardless of solder alloy type. Ensure the soldering iron tip is properly tinned and at a stable working temperature before applying solder to the joint.
