Solder wire Bisan 2.0 mm 100 g soft solder

Soft solder wire Bisan 2.0 mm 100 g soft solder is a general-purpose filler wire intended for low-temperature joining of metals. The 2.0 mm diameter spool provides a balance between feed control and melt rate, suitable for routine electrical and metalwork tasks. This solder is formulated to give consistent wetting and mechanical joint formation when used with a soldering iron or a small torch, and it is supplied on a compact 100 g spool for easy storage and handling.

Advantages

The Bisan 2.0 mm solder wire offers predictable melting and flow characteristics that simplify manual soldering operations. Its medium diameter reduces the need for frequent reloading during small- to medium-sized jobs, while maintaining fine control for precision work. The product’s composition supports reliable electrical and mechanical connections on copper, brass and similar metals used in electronics, plumbing fittings and minor metal repairs.

Suitable for

• Electronics repairs and wiring connections
• Electrical terminals and component soldering
• Plumbing fittings and light metal joining (where low-melting filler is acceptable)
• Hobby projects, model making and DIY maintenance

Key specifications

• Diameter: 2.0 mm
• Net weight: 100 g spool
• Form: Solid wire on spool for manual feed
• Intended use: Low-temperature soft soldering with soldering iron or small torch
• Compatible materials: Copper, brass and similar metals commonly used in electronics and light metalwork

How to use

Prepare the joint surfaces by cleaning away oxides, oils and contaminants to ensure good wetting. Heat the connection point with a soldering iron or torch until the base metals reach soldering temperature, then apply the Bisan solder wire to the heated area so the solder melts and flows into the joint. Allow sufficient time for the solder to form a continuous fillet, then remove heat and let the joint cool undisturbed. For electrical work, use appropriate flux and follow safety guidelines for ventilation when heating solder.

Usage recommendations

Use appropriate flux for non-tinned surfaces and select a soldering iron tip and temperature that match the 2.0 mm wire and the workpiece size. Work in a well-ventilated area and wear eye protection. For plumbing or pressurized fittings, verify the suitability of soft solder versus alternative joining methods and comply with local codes.
