Solder wire with flux 2.50 mm, 500 g spool — No name

Solder wire with integrated flux, 2.50 mm diameter on a 500 g spool is a ready-to-use alloy for general electronic and electrical soldering tasks. The thick core wire simplifies feeding and melting for larger joints, cables and connectors while the integrated flux promotes wetting and oxide removal on copper surfaces and component leads. Packaged on a practical spool, this solder wire is intended for workshop repairs, assembly work and maintenance operations where a heavier diameter is preferred.

Advantages

The combined solder-and-flux format eliminates the need for separate flux application, saving time and reducing contamination risk. The 2.50 mm diameter delivers stable deposition for larger joints and mechanical connections and reduces the frequency of wire changes during prolonged work. The 500 g spool provides extended usage between refills and keeps the wire organized for easy handling.

Suitable for

• Soldering heavy-gauge wires and cable terminations
• Joining connectors, lugs and ground points
• Workshop repairs and component replacement on boards with larger pads
• General electrical maintenance and assembly tasks

Key specifications

• Wire diameter: 2.50 mm
• Spool weight: 500 g
• Flux: integrated core flux for oxide removal and wetting
• Intended use: electronic and electrical soldering for larger joints
• Packaging: wound on a reusable spool for organized storage

How to use

Secure the workpiece and ensure surfaces to be soldered are clean and free of heavy oxidation, oil or paint. Heat the joint with an appropriately rated soldering iron or torch until the base metals reach soldering temperature, then feed the solder wire into the heated area so the alloy flows and forms a continuous fillet. Allow the joint to cool naturally; avoid mechanical stress until the solder solidifies. Use ventilation or a fume extractor when soldering to remove flux vapors.

Usage recommendations

For best results, match soldering iron wattage and tip size to the 2.50 mm wire and the thermal mass of the joint. Use additional flux sparingly only when necessary for heavily oxidized surfaces, and clean residues where required according to the application and safety guidelines.
