Product Details

Double Side Battery Tab Spot Welding Machine for EV Car Battery



Product Application

The Automatic Battery Pack Spot Welder is a general platform of automatic processing technology based on CNC, suitable battery pack spot welding and assembly in the factory. Compared with manual spot welding machine, the efficiency and accuracy of welding have been greatly improved. Humanized design makes the operation and debugging very easy and convenient. Design of components built-in makes appearance more concise. We can also offer CNC welding machine. Welcome your inquiry to us for more details.



1) Induce load voltage, control voltage by feedback, and realize high quality welding.

2) Preheat, Main Heat's power mode, preheating before welding, to ensure stable welding quality.

3) Keep the continuity of energy density, shorten the welding time, and reduce the deformation and color of base metal. (Welding time controlled in microseconds, continuous output mode)

4) Easy to change from low current to high current, suitable for precision welding.

5) The upper and lower limits of current can be set to simply judge whether the welding quality is good or not, which is suitable for welding automation platform.

6) The welding current rises with the time of electrification to ensure the welding effect.



1. Support breakpoint start, automatic start, and manual start.
2. Cold solder joint and sealing off alarm.
3. Easy program, support matrix, array and point program, can store 99 group parameters.
4. Welding needle abrasion alarm.
5. Build-in welding current monitor, can display real time welding current.
6. Design for NB, Power Tool, Gardening Tool, High Power, Energy Storage battery, Electric Motor Car Battery Pack, and other lithium battery packs spot welding.
7. High productivity: 0.35s/spot
8. Can be matched with the production line of lithium battery group.
9. Automatic battery pack spot welder adopts traditional pneumatic single point dynamic, ensure the welding accuracy, and improve the welding appearance quality and reliability.
10. Can store dozens process of different battery packs product, switching products without re-setting parameters.
11. Can match a variety brand of spot welders. 


Application Area

With the corresponding fixture, the spot welding machine can weld 18650, 26650, 32650 and other cylindrical batteries, can also be customized for a variety of cylindrical battery, square battery, button battery and etc.



1. Setting the parameters of welding on the touch screen. (The same product only need to be set once)
2. Put the fixture with the battery pack on the quick clamping position.
3. Press the start button, the machine automatically complete all welding actions.
4. The welder sound to prompt operator replacement of new fixture (battery pack).
