The China 400g Soldering Wire Spool is designed for high-volume electronics work. Whether you are a student building multiple robotics projects or a professional technician in a mobile repair lab, this bulk spool ensures you always have high-quality solder on hand. It features a 60/40 Tin-Lead alloy with an integrated 2% Rosin Flux Core, meaning you dont need extra flux for most standard soldering tasks. It melts quickly at lower temperatures, reducing the risk of heat damage to sensitive components.
Bulk 400g Spool: Huge capacity that lasts for months, significantly cheaper than buying small tubes.
Low Melting Point: High-purity 60/40 alloy ensures quick wetting and smooth flow.
Integrated Flux Core: High-quality rosin core eliminates the need for separate flux in general soldering.
Low Smoke & Splatter: Clean formula reduces toxic fumes and messy splatters on your PCB.
Shiny Joints: Produces bright, clean, and reliable solder joints that are resistant to oxidation.
