12V Spot Welding Machine Control Board Set Handheld Portable Spot Welder Diy Accessories Black

• --The welding process is based on the principle of high current and high temperature, rapid melting of part of the nickel sheet and cooling
• --High-speed single-chip microcomputer design, intelligent programming, real-time display of battery voltage, high visibility of spot welding strength
• --Adopt 8pcs MOS tube, the pe-ak current can reach 2400A, support 0.1-0.2mm nickel soldering piece, solder joint is more firm and beautiful
• --High-precision power output, 99-level of adjustable output power

Feature:

1. High-precision power output design, 99 levels of adjustable output power, more accurate welding, suitable for continuous welding of nickel plates and thousands of points on nickel plates.
2. With 3-digit digital tube real-time level position display function, it can not only display the current level position, but also detect the battery voltage to enhance the fun of spot welding.
3. When in standby, the digital tube will alternately display 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: three digits (such as 12.6), it means that the power supply voltage is: 12.6V voltage.
4. Three working modes are designed, which can be switched between normal power mode, enhanced power mode and super power mode.
5. The two-point welding delay time is adjustable, and the delay time of 0 or 1 second can be set according to the work needs.
6. It is both a spot welder and a voltmeter, with a built-in 12-bit high-precision ADC, the voltage measurement accuracy is as high as 0.01 voltage, with a test range of 8-24V, and the voltage is automatically displayed when connected to the power supply.
7. Flexible spot welding pen, 12AWG wire is composed of multi-strand high-temperature wire, which has high torsion resistance and more sensitive operation.
8. Thick pure copper soldering pen design with aluminum oxide copper spot welding pins to ensure high current passing capability and durability.
9. The cold pressing process can make the contact area of the pure copper joint larger to reduce the internal resistance.
10. You can choose one of the following power sources as the working power source:
1. Leadacid battery: 2 x 20Ah electric car battery, 36-405H new car starter battery.
2. Model battery: 3S 4000mah 35C, 3S 5000mah 25C, 3S 8000mah 20C.
3. Car starting power supply: 11.5-14.8V 36-60AH, the internal resistance should be greater than 2.5 milliohms and less than 7 milliohms.
4. Self-assembled battery: 11.5-14.8V, total internal resistance <7 milliohms.
