K-T Industries rosin-core solder wire, 40/60 tin-lead alloy, supplied as a 1 lb spool. Used for general electrical work and small electronic projects where larger-diameter wire is preferred for higher heat capacity and quicker joint feeding.

• Alloy: 40/60 tin-lead with rosin flux core
• Wire diameter: 1/8" (the largest of the K-T rosin-core lineup)
• Spool weight: 1 lb
• Pre-fluxed - no separate flux required for clean copper
• Use for splicing wires, terminal lugs, and other general electrical joints

Tip: Lead-bearing solder. Work in a ventilated area, do not eat or drink at the bench, and wash hands after handling. For fine surface-mount or printed-circuit work step down to the 3/32" or 1/16" diameter spools.
