Description
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.
Key Features:
🔩 Designed for Copper-to-Copper Welding
Perfect 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 Additives
Infused 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 Resistance
This 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 Safe
Safe 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 Current
To 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.
