Function introduction: This circuit will become an energy storage spot welding machine with 12V battery. It is used for welding nickel plates such as lithium batteries & nickel-chromium batteries. According to different configurations, the welding thickness can be about 0.1MM-0.15mm. We have customers By replacing the thicker wire (10 square) can barely weld 0.2MM thickness. After all, this device is geared towards electronics enthusiasts, & the frequency of use will not be very high, so 0.1-0.15 welding 2 can also be used to replace thicker nickel sheets. Button function: The button can switch modes, each mode corresponds to different welding time, LED corresponds to red / green / blue / white / yellow / pink / violet, 7 modes, the red time is the shortest, & the violet welding time is the largest. Long press to set the waiting time, the default is 3 seconds, the maximum can be set to 10 seconds. Basic parameter: Power supply voltage: 12V-16.8V (capacity X ratio = must be greater than 150A) Current requirement: greater than or equal to 150A instantaneous output (such as car starting power supply, 3S model high-rate battery pack, 12V lead acid battery with good performance above 20A) Packaging included:1 X PCB Circuit Board ...
