Description:
This is a high-quality spot welding machine control board.
This spot welding machine can be used for spot welding of 14650/17490/18650/21700/26650/32650 lithium cylindrical batteries and nickel-metal hydride batteries.
Feature:
Using 5 MOS tubes, the maximum current can reach 2390A.
High power output design, 99-speed adjustable output power, more precise welding, thousands of points can be continuously welded on nickel sheet/nickel plate.
Welding is the principle of using high current and high temperature to rapidly melt the nickel foil part and cool it.
Equipped with 2 copper bars, which greatly increases the overcurrent capacity.
The welding spot is accurate and beautiful, and supports welding of 0.05-0.2mm nickel sheet, iron sheet and stainless steel sheet.
