Lithium Battery Spot Welder
🔥 Lithium Battery Spot Welder | Lion Battery
A Lithium Battery Spot Welder is an essential tool used for connecting nickel strips to Lithium-ion and LiFePO4 battery cells during battery pack assembly. Unlike soldering—which can overheat and damage battery chemistry—spot welding creates a strong, low-resistance electrical connection using precise, high-current pulses.
At Lion Battery, we offer portable, handheld, and industrial-grade spot welders suitable for DIY hobbyists, repair technicians, and professional battery manufacturing.
⚙ How a Spot Welder Works
Spot welding applies a short burst of high current through nickel strips placed on battery terminals. The pressure and heat fuse the strip to the cell without overheating the internal structure.
This ensures:
- ✔ Safe cell bonding
- ✔ Strong mechanical attachment
- ✔ Low resistance for efficient current flow
