Solder Wire CYNEL 3.0 mm Spool 250 g — Leaded/Unspecified Alloy WG-01X-01-1-300-4

CYNEL solder wire on a 250 g spool with 3.0 mm diameter provides a heavy-gauge feed for manual soldering and rework operations. The spool format keeps the wire tidy and ready for use in workshop and repair environments. This product is intended for applications requiring a relatively thick solder wire to form larger fillets or to supply solder quickly when working on bigger joints; alloy type and flux content are unspecified, so users should confirm compatibility with their components and process.

Advantages

The 3.0 mm diameter wire offers rapid solder deposition for larger joints, reducing time needed when filling gaps or building fillets. A 250 g spool balances quantity and manageability for bench work, prototyping and repairs. The product's straightforward spool format simplifies handling and storage and supports steady feed during manual soldering and rework tasks.

Suitable for

• Workshop and repair tasks involving larger electrical or mechanical joints
• Prototyping where thicker solder wire speeds up assembly
• Manual soldering and rework requiring quick solder supply
• Applications where a larger fillet or gap filling is needed

Key specifications

• Wire diameter: 3.0 mm
• Spool weight: 250 g
• Format: spool for manual use
• Intended use: soldering and rework for larger joints

How to use

Prepare the surfaces by cleaning and, if necessary, removing old solder or oxidation. Select a soldering iron and tip appropriate for the larger wire diameter and the joint size; higher thermal capacity tips and irons are recommended for better heat transfer. Feed the 3.0 mm wire steadily into the heated joint area so that the solder melts and wets the surfaces evenly. Work in short bursts to avoid excessive heat exposure to sensitive components; if flux is required and not included, apply a suitable flux before soldering. After soldering, clean any flux residues according to the flux type used and inspect the joint for proper wetting and fillet formation.

Usage recommendations

Verify alloy and flux compatibility with your components and, if necessary, test on scrap material before critical assemblies. Use appropriate personal protective equipment and sufficient ventilation when soldering. For fine electronics or components sensitive to heat, consider using thinner diameter solder wire or pre-tinning techniques to reduce thermal stress.
