Product details

• There is a window on the back of the drive part, you can add copper or tin by yourself.
• The external pads for the LE-D and the on-board buttons are added to facilitate the connection of the LEDs and buttons on the board to other places.
• The upper and lower MOS design is bold and tinned to make the internal resistance smaller and the current stronger.
• Using 25V low internal resistance and high frequency capacitors makes the power supplies more stable.
• This circuit with a 12-V batt-ery will become an energy storage spot welding machine for welding nickel pieces such as lithium batt-eries and nickel-chromium batt-eries. According to different configurations, the thickness can be about 0.1mm-0.15mm

This product is very useful in daily life, with an batt-ery, it will become an energy storage spot welding machine for welding nickel pieces such as lithium batt-eries and nickel-chromium batt-eries practical, easy to operate and use, wide application range, has a long service life. Come on and try it.
