Weller T0051403099 Lead Solder Alloy 100g Spool

Product Description

The WELLER T0051403099 is a lead-based solder supplied on a 100-gram spool. It is formulated from a tin-lead alloy and is used for hand soldering, solder robot applications, and rework across a wide range of industries. The wire diameter measures 1.0 millimeter, making it suitable for general through-hole and surface-mount work. The alloy begins to melt at 361.4 degrees F and reaches full melt at 374 degrees F, a narrow working range that supports consistent joint formation. Licensed electricians, electronics technicians, and assembly professionals are the primary users of this product.

This solder wire is suited for electrical and electronic assembly, repair work, and production-level soldering in residential, commercial, and industrial settings. Its stated application range covers electronics repair, home projects, automotive, solar, military, aerospace, and medical device assembly. The 100-gram spool size is practical for bench work and low-to-mid volume production use. The 1.0 mm diameter fits a broad range of iron tip sizes and component lead gauges.

Installation Notes

Soldering work should be performed by qualified technicians following applicable industry standards such as IPC-J-STD-001 for soldered electrical and electronic assemblies. Ensure adequate ventilation when working with lead-based solder to minimize flux fume and lead particulate exposure. Power down and de-energize all circuits before soldering on live assemblies. Follow local regulations regarding the handling and disposal of lead-containing materials.
