Solder wire with flux, diameter 3.00 mm, 250 g, No name

Solder wire with integrated flux, 3.00 mm diameter on a 250 g spool. Designed for general-purpose soldering of electrical and electronic components, metal joints and repair tasks. The built-in flux promotes wetting, reduces oxidation and helps form reliable solder joints when used with standard soldering irons and stations. The 3.00 mm diameter and substantial spool weight suit tasks where higher feed rate and longer uninterrupted work are required.

Advantages

The integrated flux eliminates the need for separate flux application, simplifying preparation and reducing handling steps. A 3.00 mm diameter core provides faster material deposition compared with thinner wire, which is useful for filling gaps, plumbing-like joints or heavier electrical joints. The 250 g spool supports extended work sessions without frequent spool changes and is compact enough for storage in workshops or tool kits.

Suitable for

• Soldering of wires, terminals and connectors in electrical repairs
• Joining thicker metal parts and mechanical joints
• General electronics maintenance where larger-diameter wire is appropriate
• Hobby and DIY projects requiring robust solder joints

Key specifications

• Diameter: 3.00 mm
• Spool weight: 250 g
• Flux: integrated core flux
• Intended use: manual soldering with standard soldering irons and stations
• Application areas: electrical, electronic and general metal repair

How to use

Prepare the surfaces by cleaning away dirt, grease and oxidation to ensure proper wetting. Heat the joint with a suitably powered soldering iron or station, apply the solder wire to the heated area and allow the solder to flow and cover the joint. Avoid excessive heating time to prevent damage to components or surrounding materials. After soldering, allow the joint to cool naturally and, if necessary, clean any residual flux according to the flux type and the requirements of the workpiece.

Usage recommendations

Use appropriate personal protective equipment, adequate ventilation and temperature settings matched to the workpiece. Select this 3.00 mm solder wire for larger joints and repairs; for delicate electronics or very small components, consider thinner diameter solder wire to improve control and reduce heat exposure.
