Solder wire CYNEL C-D6 2 250 — tin solder, 2.5 mm diameter, 250 g

CYNEL C-D6 2 250 is a tin solder wire supplied on a 250 g spool with a 2.5 mm diameter core. This product is sold without flux, intended for manual soldering and repair work where a separate flux is preferred or when working on assemblies that do not require an integrated flux core. The tin composition makes it suitable for joining small metal parts and electronic components, and the spool format supports repeated use in workshop and repair environments.

Advantages

The solder wire provides consistent diameter and uniform feed from a compact spool, enabling steady soldering performance for hand tools and soldering irons. Being supplied without flux allows users to select a flux type appropriate to the application or use the wire where no flux is needed. The 2.5 mm diameter balances melting speed and control for medium-sized joints, and the 250 g weight offers a practical quantity for repair tasks and small production runs.

Suitable for

• Manual soldering of electronic components and wires
• Repairing small plumbing or metal fittings where tin solder is acceptable
• General metal joining tasks requiring a tin-based wire without flux core
• Workshops and hobbyist repair stations needing a reusable spool format

Key specifications

• Material: tin-based solder wire (no flux included)
• Diameter: 2.5 mm
• Spool weight: 250 g
• Form: solid wire on spool for manual feeding

How to use

Prepare the surfaces to be joined by cleaning and, if required, applying an appropriate separate flux. Heat the joint with a compatible soldering iron or torch until the metal reaches soldering temperature, then apply the CYNEL C-D6 2 250 wire to the heated area so the solder flows and wets the surfaces. Allow the joint to cool naturally and inspect for proper wetting and fillet formation. Store the spool in a dry place away from contaminants to preserve solderability.

Usage recommendations

Use a flux compatible with the metals being joined to ensure good wetting and to prevent oxidation. Select soldering iron temperature based on joint size and thermal mass; for moderate-sized joints with 2.5 mm wire, use a heat source capable of maintaining stable temperature to allow proper flow. Wear appropriate personal protection and ventilate the work area when heating solder alloys.
