4Pcs Solder Wire 0.8mm 60/40 Leaded Flux Core Welding Wire 20g Silver

Product features

1. Four Rolls With Generous Weight: Each roll contains 20 g of 0.8 mm Solder Wire — double the weight of standard 10 g rolls in the same category. Compact spools measuring 4.5 cm in diameter by 2.3 cm high, giving enough wire across four rolls for multiple repair sessions without constantly reaching for a new pack
2. 60/40 Leaded Composition: The balanced tin-lead alloy melts at a predictable temperature and flows smoothly into joints. Wets pads and leads evenly, producing shiny reliable connections that hold over time — the proven formula for general electronics soldering and hobbyist circuit building
3. Built-In Flux Core: A continuous flux core runs through the centre of the wire, activating on contact with heat to clean oxides from the soldering surface. Reduces the need for separate flux paste and helps each joint form cleanly with fewer cold spots or bridging between adjacent pins
4. Consistent 0.8 mm Diameter: The uniform wire gauge feeds through standard soldering irons and rework stations at a steady rate. Fine enough for close-pitch component legs and PCB traces, yet thick enough to build fillets on larger through-hole connections without doubling up
5. Versatile Electronics And DIY Use: Suitable for circuit board maintenance, component replacement, wire splicing, DIY kit assembly, RC model repair and general electrical connections. Works with smartphones, radios, televisions, toys, motor controllers and breadboard projects — covering the full range of home workshop electronics tasks
