Weller T0051388499 Lead Free Solder Spool 100 G

Product Description

The WELLER T0051388499 is a lead-free solder supplied on a 100 g spool, formulated from a tin-based alloy for use across a wide range of electrical and electronic soldering applications. With a melting range of 422.6 degrees F to 429.8 degrees F and a wire diameter of 0.5 mm, this solder is suited for precision work where consistent flow and clean joints are required. It meets lead-free requirements applicable to commercial, military, aerospace, and medical device assembly environments. Licensed electricians, electronics technicians, and field service professionals are the typical end users.

This solder is appropriate for residential and commercial electrical repairs, PCB assembly, automotive electronics, solar panel wiring, and robotic soldering applications. The 0.5 mm diameter wire is well suited to fine-pitch work on circuit boards and small connectors. The 100 g spool format is practical for bench technicians and field kits alike, offering enough material for extended service sessions without the bulk of larger spools.

Key Features

• Lead-free alloy formulation meets RoHS and lead-free assembly requirements
• Melting range of 422.6 degrees F to 429.8 degrees F for controlled reflow
• 0.5 mm wire diameter supports fine-pitch and precision soldering work
• 100 g spool provides sufficient material for extended bench or field use
• Suitable for electric, electronic, repair, robotic, military, aerospace, medical device, automotive, and solar applications

Compatibility

Designed for use with standard soldering irons and soldering stations compatible with 0.5 mm lead-free solder wire; suitable for electrical, electronic, and PCB repair applications across residential, commercial, and industrial settings.

Installation Notes

Soldering work on live electrical circuits must be performed only after power has been de-energized and locked out per applicable NEC or site safety requirements. Use a calibrated soldering iron or station set to a temperature appropriate for the alloy melting range. Adequate ventilation is required when soldering, as flux fumes can be an irritant. Dispose of solder waste in accordance with local regulations even when using lead-free alloys.
