2pcs Solder Wire + Rosin Paste Flux Set - Welding Wire 60/40 Rosin Core Tin with Soldering Flux

Solder Wire: Included in the kit is a high quality 60-40 (Sn/Pb) Tin - Lead rosin core solder wire alloy with 1.0mm diameter and 1.8% flux content commonly used for wiring appliances, DIY projects, 3D printers and other electronic projects or electrical and electronics soldering and repairs.

Rosin Paste Flux: This high-quality rosin flux soldering paste facilitates the flow of solder, thus increasing the efficiency of the soldering process and is just right for your small DIY soldering projects.

The solder wire has a low melting point and a fast melting speed to protect the complete functionality of the components
Soldering wire no spraying, very few residues, bright and reliable soldering joint
The tin solder wire is widely used in electrical soldering, circuit maintenance, mobile phone circuits, computer motherboards, etc.
Soldering flux can clean the soldering head, prevent oxidation of the soldering head, promote the soldering flow, allow the solder to form strong, durable mechanical and electrical connections, improve welding efficiency
