The WELLER T0051386999 is a lead free solder supplied on a 500 g spool, formulated from a tin-based alloy designed for clean, reliable joints in electrical and electronic work. With a melting range of 422.6 degrees F to 429.8 degrees F and a wire diameter of 0.8 mm, it suits precision soldering applications where tight temperature control is required. The spool format keeps the wire tangle-free and feeds smoothly through automated and hand-soldering setups alike. Licensed electricians, electronics technicians, and field service pros working on control boards, sensors, and wiring harnesses reach for this type of solder when RoHS-compliant, lead free joints are required.
This solder is suited for a wide range of applications including residential and commercial electrical repair, electronics assembly, robotic soldering lines, automotive wiring, solar panel assembly, aerospace, military, and medical device manufacturing. The 0.8 mm diameter is well matched to fine-pitch through-hole and surface-mount work where excess material at the joint is a concern. The 500 g spool size supports bench technicians and field service operations that need a reliable supply without frequent restocking.
Designed as a general-purpose lead free solder wire for electrical, electronic, repair, robotic soldering, home project, military, aerospace, medical device, automotive, and solar applications.
This solder is installed by licensed electricians, electronics technicians, and qualified soldering professionals. Before soldering any live circuit or control board, power down the equipment and discharge capacitors following standard lockout and tagout procedures. Use a soldering iron or soldering station calibrated to the appropriate tip temperature for the alloy melting range. Lead free alloys typically require slightly higher iron temperatures than tin-lead solders, so verify your equipment settings before beginning work.
