Professional solder wire designed for audio technicians, sound engineers, and DIY builders who need reliable connections for PA systems, speaker repairs, and cable assemblies. This 1.0mm diameter solder handles everything from fixing loose XLR connections to rebuilding crossover networks in your monitor wedges. The 60/40 tin-lead composition with flux core delivers consistent flow and strong joints that won't fail during load-in or breakdown. At .031 inches (1.0mm) diameter, this solder provides the right balance of material flow and precision control for delicate driver connections and heavy-duty power cable work. Each one-pound spool contains enough solder for dozens of repair jobs. The flux-core design eliminates the need for separate flux application, speeding up repair work when you're troubleshooting a dead channel between sets. The 60% tin content ensures proper wetting on copper conductors and component leads, while the 40% lead provides mechanical strength for connections that see vibration and thermal cycling. Use this solder for repairing speaker cables, fixing loose connections on input plates, reconnecting blown drivers, and building custom cable assemblies. It works equally well for delicate crossover component work and heavy-duty power connections on amplifier racks. Professional-grade solder that meets the demands of touring rigs and permanent installations. Seismic Audio backs this product with fast shipping and responsive customer support when your repair work can't wait. Technical Specifications Spec Value Diameter 1.0mm (.031") Weight 1 lb spool Composition 60% Tin / 40% Lead Core Type Flux core Model SA-Solder Condition Brand New Recommended For Audio equipment repair and cable assembly Frequently Asked Questions What audio equipment can I repair with this solder? This solder works for all standard audio repair tasks including speaker driver connections, XLR and TRS connector assembly, input jack repairs, and crossover component replacement. The 1.0mm diameter and flux core make it suitable for both delicate circuit board work and heavy-duty cable terminations. It's commonly used for PA speaker repairs, monitor wedge rebuilds, and custom cable fabrication. Do I need additional flux when using this solder? No additional flux is required. This solder contains flux in the core, which automatically cleans oxidation and promotes proper wetting as you work. The integrated flux eliminates an extra step and ensures consistent results whether you're doing quick field repairs or detailed bench work on crossover networks. How much repair work will one pound of solder handle? A one-pound spool provides enough material for approximately 50-100 typical audio repairs, depending on joint size. This covers everything from reconing several 15-inch woofers to building a complete set of custom XLR cables for a small PA system. Most technicians find this quantity lasts 6-12 months of regular repair work. Is this solder suitable for both component-level and cable work? Yes, the 1.0mm diameter works well for both applications. It's thin enough for precise work on crossover capacitors and resistors, yet provides sufficient material flow for larger joints like power cable lugs and speaker terminals. The 60/40 composition offers the right balance of flow characteristics and mechanical strength for audio applications. What temperature soldering iron should I use with this solder? Use a soldering iron set between 350-400°F (175-200°C) for most audio work. This temperature range ensures proper flow without overheating sensitive components like crossover capacitors or driver voice coil leads. For heavy cable work, you may need slightly higher temperatures around 400-450°F to heat larger conductors effectively.
