Weller T0051387999 Silver Free Alloy Solder Spool 500 G

Product Description

The WELLER T0051387999 is a silver free alloy solder supplied on a 500 g spool with a 0.8 mm diameter wire profile. It is designed for joining electrical and electronic components and is suited to both hand soldering and automated solder robot applications. The alloy formulation has a minimum melting temperature of 442.1 degrees F, providing reliable flow characteristics across a range of soldering irons and station temperatures. Licensed electricians, electronics technicians, and production line operators are the primary installers and users of this material.

This solder is appropriate for residential and commercial electrical work, printed circuit board assembly, repair bench work, and automated wave or robot soldering processes. Stated application areas include electric and electronic assembly, repair, home projects, military, aerospace, medical device manufacturing, automotive, and solar. The 500 g spool size suits both low-volume repair shops and higher-throughput production environments where a compact, single-spool supply is practical.

• 500 g spool provides extended run time before resupply
• Minimum melting temperature of 442.1 degrees F for predictable reflow behavior
• Compatible with solder robot, wave, and manual iron processes
• Broad application range including automotive, aerospace, solar, and medical device assembly

Compatibility

Designed for use in electric and electronic assembly, repair, solder robot, home projects, military, aerospace, medical device, automotive, and solar applications as stated by the manufacturer.

Installation Notes

Soldering work on live circuits or energized equipment must never be performed — power down and discharge capacitors before starting any solder repair. Adequate ventilation or fume extraction is required when soldering any alloy material. Technicians should verify that iron tip temperature and dwell time are appropriate for the alloy melting point before beginning production or repair runs. Dispose of solder waste in accordance with applicable local and federal regulations governing metal alloy materials.
