About the Weller T0051386999 Solder Wire, SAC 0.8mm
Weller WSW SAC L0 is a lead-free solder wire; this reel is 0.8 mm in diameter and holds 500 g. The alloy is Sn96.5/Ag3.0/Cu0.5, a tin-silver-copper composition with a melting range of 217-221 degC, and the wire carries a 3.5 % flux content classified L0 to J-STD-004, meaning halogen-free with low activity. Weller specifies a continuous flux core through the wire so that flux delivery does not break part-way through a joint, and describes the alloy as reduced-splash in use. At 0.8 mm this T0051386999 lead-free solder wire is the finer of the two 500 g reel gauges BOLTON lists, depositing a smaller volume of solder per unit length fed, which gives more control on closely spaced joints and on components that will not tolerate excess fillet. The wire is manufactured in Japan and is declared under HS code 8311.30.00.

Typical applications
A 0.8 mm gauge is the usual choice for surface-mount rework, fine-pitch device replacement, small through-hole joints and instrument-level repair, where a thicker wire would overshoot the required solder volume before the operator can stop feeding. The lead-free SAC alloy suits assemblies built to RoHS-compliant process requirements. The 500 g reel size is a bench-stock quantity for a production or rework station.
