Weller Wire, 0.8 mm Lead Free Solder, 217 °C Melting Point

This lead-free solder is a wire-form alloy designed for Electronic Assembly and repair, providing a rosin-fluxed option for controlled soldering on electrical and mechanical assemblies. It operates as a low-oxide, tin-rich solder for general-purpose joining of components where lead-free materials are required.

• 0.8mm wire diameter for precise hand and machine feeding
• 96.5% tin composition enabling solid wetting performance
• 3% silver content improving joint strength and fatigue resistance
• 0.5% copper addition reducing solder joint voiding
• 217°C melting point allowing predictable thermal profiling
• 250 g spool size supporting medium-volume workstation use

• Suitable for through-hole component soldering in control boards
• Ideal for rework and repair of electronic assemblies
• Used with pick-and-place solder feeders for small-batch production
• Can be used for assembly of sensor modules in automation systems
• Suitable for soldering connectors and cable terminations in electrical panels

The built-in rosin flux promotes stable flux activity at typical reflow and hand-solder temperatures, aiding solder flow and reducing oxide formation at joints.

The silver content increases creep resistance while the high tin fraction maintains good wetting, together producing joints that better withstand repeated temperature variation.

It is compatible with manual iron soldering and most wave and selective soldering processes when used with appropriate thermal profiles.

Keep the spool dry and sealed from contaminants
