Solder wire spool CYNEL 1.0 mm 250 g (WG-01X-01-1-100-4)

CYNEL solder wire on a 250 g spool with a 1.0 mm diameter is filler metal in wire form intended for manual soldering and rework of electronic components, cable joints and general electrical connections. The compact spool format provides neat storage and controlled dispensing, making the wire suitable for use with standard soldering irons and soldering stations that accept a 1.0 mm core wire. The product is presented as ready-to-use solder wire for typical electronics and electrical repair tasks.

Advantages

The 1.0 mm wire diameter balances ease of feeding with sufficient mass for reliable joints on small to medium connections. The 250 g spool reduces the frequency of replacements compared to smaller reels and is convenient for workshop use or field service. The compact spool supports tidy storage and controlled unwinding, while the wire form is compatible with common manual soldering workflows.

Suitable for

• Soldering and rework of printed circuit board components
• Repairing and joining insulated cables and wiring harnesses
• General electrical connections and terminal soldering
• Prototyping and small batch assembly where 1.0 mm core wire is preferred

Key specifications

• Wire diameter: 1.0 mm
• Spool weight: 250 g
• Form: solid core solder wire on a spool
• Intended use: manual soldering and rework for electronics and electrical connections
• Compatibility: standard soldering irons and soldering stations accepting 1.0 mm wire

How to use

Prepare the joint by cleaning contact surfaces from oxidation, dirt and insulating residues. Heat the joint with an appropriate soldering iron or station until the surfaces reach soldering temperature, then apply the CYNEL solder wire to the heated area allowing the solder to flow and form a continuous fillet. Remove heat and allow the joint to cool undisturbed. For through-hole components, apply solder to the heated lead and pad; for cable joints, feed solder into the heated overlap area. Follow standard safety practices such as working in a ventilated area and using appropriate personal protective equipment.

Usage recommendations

Use a suitable flux or flux-core variant if flux is not present in the wire to ensure good wetting and reliable joints. Adjust iron temperature to the component and solder alloy in use to avoid thermal damage: typically use lower temperatures for small electronic parts and higher temperatures for larger wires or connectors. Store the spool in a dry, cool place to prevent contamination and oxidation.
