Weller T0051403299 Lead Solder Spool 100g

Product Description

The WELLER T0051403299 is a lead-based alloy solder supplied on a 100 g spool, designed for hand soldering, automated solder robot applications, and bench repair work across electrical and electronic trades. The solder wire measures 0.5 mm in diameter, offering fine control for precision joints on small components and circuit boards. Melting range runs from 361.4 degrees F to 374 degrees F, placing it in the typical tin-lead eutectic range suited for controlled heat applications. Licensed electricians, electronics technicians, and avionics or military depot repair shops are the primary installers and users of this product.

This solder is formulated for a broad range of applications including general electrical repair, electronic assembly, solar panel wiring, automotive electronics, and medical device manufacturing. The 100 g spool format is well-suited to bench technicians who need a manageable quantity for service calls or low-volume production. Its fine 0.5 mm diameter makes it appropriate for work on densely populated PCBs and small terminal connections where heat control and minimal solder volume are critical.

Installation Notes

This product should be handled by qualified electricians, electronics technicians, or other licensed trade professionals familiar with lead-based solder safety requirements. Work in a well-ventilated area and follow applicable OSHA guidelines for lead exposure when using lead-bearing solder. Power down and discharge all capacitors in electronic assemblies before soldering to prevent damage to components or risk of shock. Wash hands thoroughly after handling lead solder and dispose of waste material in accordance with local regulations.
