Lithium Battery Spot Welder Solder Joints Turn Black

This is because the spot welding machine has not been debugged well. For nickel sheets of different thickness, different currents and delays need to be set at the same time, they are affected by the high strength material. the current to a smaller value, and materials with small resistance need to adjust the current to a smaller value. Increase the current, and the product should be clean and free of oil. In addition, the wear of the welding needle will also affect. the welding effect. The smaller the contact area between the welding needle and the nickel sheet, the higher the pressure and the better the welding effect.
