Description

The WELLER T0051386499 is a lead-free solder supplied on a 500 g spool, formulated from a metal alloy designed for reliable, clean joints in electrical and electronic soldering applications. It has a melting range of 422.6 degrees F to 429.8 degrees F, which is consistent with standard lead-free alloy behavior and compatible with most temperature-controlled soldering stations. The wire diameter is 0.5 mm, making it well suited for fine-pitch electronic work as well as general wiring and repair tasks. Licensed electricians, electronics technicians, HVAC technicians, and PCB repair specialists are the primary users of this product.

This solder is applicable across a wide range of industries and project types. The manufacturer lists the following intended applications: electric, electronic, repair, solder robot, home projects, military, aerospace, medical device, automotive, and solar. The 500 g spool size is practical for bench technicians and field service professionals who solder frequently and need a reliable bulk supply. The lead-free composition meets modern environmental and safety requirements and is appropriate for RoHS-compliant work.

Key Features

Lead-free alloy formulation suitable for RoHS-compliant and environmentally regulated applications
0.5 mm wire diameter supports fine-pitch PCB work and precision electronic soldering
Melting range of 422.6 degrees F to 429.8 degrees F for use with calibrated lead-free soldering stations
500 g spool provides high-volume supply for frequent bench or field use
Rated for use across electrical, automotive, aerospace, solar, and medical device applications

Compatibility

Designed for use with temperature-controlled lead-free soldering stations and irons capable of reaching and sustaining lead-free working temperatures. Suitable for electrical, electronic, automotive, solar, aerospace, medical device, and robotic soldering applications as specified by the manufacturer.

Installation Notes

Use with a soldering station calibrated for lead-free alloys, as lead-free solder requires higher iron tip temperatures than traditional tin-lead solder. Ensure adequate ventilation at the work area when soldering, as flux fumes are a respiratory hazard. Follow applicable workplace safety standards and, where required, IPC soldering standards for the target application. Store the spool in a cool, dry location to prevent oxidation of the wire surface.
