1. 6 low internal resistance MOS tube, single 300A, improve circuit stability 2. The voltage stabilizing circuit is designed to make the MOS drive voltage no longer dependent on the battery, more stable and reliable, so that the board can support 6-24V wide voltage use 3. The new circuit layout greatly reduces the internal resistance, generates less heat, and welds more firmly 4. The external interface of LED and button has been added to facilitate the installation of the board in the shell

Working voltage: 6-24VDC (recommended to use within 6-18VDC, because the voltage is too high, the spark will be very large, and it is difficult to weld) Working current: 90-200A (the best working current is about 150A, if the current is too small, it will not be able to weld firmly) Optional power supply: 1.36-60AH car start battery 2.20AH motorcycle battery 2 to 3 in parallel 3.2S-5S 4000mah Lithium-ion battery with discharge above 30C
