Flux for Copper-to-Copper Spot Welding (100g)

This Flux for Copper-to-Copper Welding is specifically engineered for lithium battery builders who want to spot weld copper with confidence. If you're working with copper tabs, terminals, or busbars, this is the secret weapon that helps you achieve strong, low-resistance welds without pushing your welder to the max. Limited U.S. inventory This specialized copper spot-welding flux is currently difficult to replenish internationally. Current pricing reflects limited replacement availability and inventory already stocked in Florida for faster domestic delivery. Key Features: 🔩 Designed for Copper-to-Copper WeldingPerfect for welding pure copper components in high-performance battery packs. Whether you're using copper strip, terminals, or bus connections, this flux allows for solid welds with minimal current loss. ⚡ Nickel and Tin AdditivesInfused with a special blend of nickel and tin, the flux improves heat transfer and bonding between copper surfaces. When activated, it creates a temporary conductive alloy layer, making welding easier and stronger. 🔥 Reduces Welding ResistanceThis flux heats up the copper at the weld point, reducing resistance and helping your spot welder deliver a cleaner, more effective weld — even on thick copper. 🧪 Non-Corrosive and SafeSafe for long-term use in battery environments. This flux does not corrode terminals, cell tops, or other conductive materials — ideal for precision welding on energy storage applications. ⚙️ Optimized for 2000A–8000A Welding CurrentTo achieve proper copper spot welding, your machine must deliver high enough current. This flux enables effective results even in difficult scenarios, including transformer and energy storage welders.
