The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes press the workpiece to make the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other At the moment, the instantaneous thermal welding is formed at the two contact resistance points, and the welding current instantaneously flows from the other electrode along the two workpieces to this electrode to form a loop, and does not hurt the internal structure of the workpiece being welded.

Scope of application: power battery 18650/26650/21700 battery cell serial-parallel combination, multi-parallel multi-string combination, power tool battery, twist car battery (1 mold spot welding 6 groups), energy storage battery pack, 18650 battery pack, 26650 battery pack, 32650 battery pack, electric bicycle battery, solar street light battery pack, ternary lithium battery, digital lithium battery, lithium iron phosphate battery, etc.

Today, the custom double sides automatic welding machine has been shipped to our USA customer, used for welding large battery packs, this is the second time they purchased a spot welding machine from our company, we will provide you with reliable equipment and excellent after-sales service.

We also can provide a automatic battery pack solution, if you are intersted in it, feel free to contact me. Thank you for reading!
