Solder wire spool CYNEL 2.5 mm 250 g — lead-free? (WG-01X-01-1-250-4)

CYNEL solder wire spool with 2.5 mm diameter and 250 g net weight is supplied on a reel for manual or workshop soldering. It is intended as a general-purpose solder consumable for electrical and electronics assembly, repair work and metal joining where a medium-thickness wire is appropriate. The product listing does not specify flux type or alloy composition in the title, so users should verify flux formulation and alloy details before application.

Advantages

The 2.5 mm diameter offers a balance between feedability and heat transfer for medium-sized joints; the 250 g reel provides a compact, easy-to-store supply for workshop benches. Supplied on a reel, the solder wire remains organized and minimises tangling during repeated use. The design suits a range of manual soldering irons and basic station feeders commonly used in electronics repair and light metalwork.

Suitable for

• Manual soldering of electrical and electronic components
• Repair and refurbishment tasks on circuit boards and wiring
• Joining small metal parts and soft soldering in mechanical assemblies
• Workshop use where medium-thickness solder wire is preferred

Key specifications

• Wire diameter: 2.5 mm
• Net weight on reel: 250 g
• Packaging format: spool/reel for manual handling
• Intended application: general-purpose soldering for electronics and metal joining

How to use

Prepare the work surfaces and clean component leads or metal parts to remove oxides and contaminants. Select an iron or soldering station with appropriate tip size and temperature for the joint size and alloy type you will confirm from the product label. Feed the solder wire from the reel to the heated joint, applying heat to the parts rather than the wire; allow the solder to flow and wet the surfaces before removing heat. After soldering, trim excess wire and inspect the joint for proper wetting and fillet formation. Follow standard safety practices including adequate ventilation and eye protection.

Usage recommendations

Verify flux type and alloy composition printed on the product packaging or technical datasheet before use. Match soldering temperature and tip size to the wire diameter and alloy to avoid cold joints or component damage. Store the reel in a dry environment to prevent contamination of the flux core.
