Solder wire with flux, 2.00 mm diameter, 250 g, No name

Solder wire with integrated flux, 2.00 mm diameter and 250 g spool weight. This general-purpose solder wire is intended for soldering electrical and electronic components, wire joints and PCB connections where a medium-thickness wire is required. The integrated flux in the core facilitates wetting, reduces oxidation during heating and supports consistent solder flow for both manual and mechanized soldering operations.

Advantages

The flux-core design eliminates the need to apply separate flux in many common soldering tasks, saving time and ensuring clean joints. The 2.00 mm diameter delivers a balance between melt speed and control, suitable for larger component leads and thicker wiring while still usable on medium pads. The 250 g spool provides enough material for repair, prototyping and small-scale production without frequent spool changes. The wire is compatible with standard soldering irons and many soldering stations, enabling straightforward integration into existing workflows.

Suitable for

• Repairing electrical wiring and connectors
• Soldering through-hole electronic components and larger pads
• Prototyping and assembling small electronic devices
• General-purpose workshop and hobby soldering tasks

Key specifications

• Wire diameter: 2.00 mm
• Spool weight: 250 g
• Flux: core-integrated flux for better wetting and reduced oxidation
• Wire form: solid round wire suitable for manual feed and mechanized dispensers
• Intended use: electrical and electronic soldering, wire joints, PCB pads

How to use

Prepare surfaces by cleaning off oxidation, grease and contaminants for optimal wetting. Heat the joint with a soldering iron or station to the appropriate temperature for the solder alloy and the workpiece. Apply the solder wire to the heated joint so the solder flows into the connection; allow the integrated flux to assist in removing oxides and improving flow. Remove heat once sufficient solder has wetted the surfaces and allow the joint to cool undisturbed to form a reliable connection. For mechanized dispensing, set feed rate and temperatures according to equipment specifications and the wire diameter.

Usage recommendations

Use appropriate ventilation when soldering and follow safety practices: wear eye protection, avoid inhaling fumes, and wash hands after handling. Select a soldering tip and temperature appropriate for 2.00 mm wire and the components being worked on; higher thermal mass joints may require increased heat. Store the spool in a dry environment to preserve flux performance.
