Features: Adopt 8pcs MOS tube, the peak current is up to 2400A, support 0.1-0.2mm nickel soldering piece, the solder joint is firmer and more beautiful. The high-precision power output design with 99 levels of output power can be adjusted to achieve more accurate welding, suitable for continuous welding of nickel plates and thousands of points on nickel plates. It has the function of displaying the real-time level position of the 3-digit digital tube, which can not only display the current level position, but also detect the battery voltage to enhance the fun of spot welding. When in standby, the digital tube will alternately display the level position and power supply voltage every second. When the display shows: d+ two digits, it means that it is in the level display state; when the display shows: 3 digits (such as 12.6), it means that the power supply voltage is: 12.6V voltage. 3 working modes are designed, which can be switched between normal power mode, enhanced power mode and super power mode. Specifications： Working voltage: 8-24V Working current:
