6V 12V 24V Lithium Li-ion Battery Welder Control Handheld DIY Control Board Set Spot Welding Machine Tool Main Circuit B

Main Features ● The board uses 6 MOS tubes with extremely low internal resistance a single 300A Greatly improve circuit stability ● The voltage stabilizing circuit is designed to make the MOS drive voltage no longer depend on the battery and is more stable and reliable so that the board supports 6 24V wide voltage use ● The new circuit layout greatly reduces the internal resistance the heat is smaller and the soldering is more laborious ● The external interface of LED and button has been added which is convenient to install the board in the box ● Optimized the program to make the operation more smoothly and freely SpecificationVoltage 6 24V it is recommended to use within 6 18V because the voltage is too high the sparks will be large and it is difficult to weld Working current 90 200A working current is about 150A if the current is too small it will be impossible to weld Application1 36 60AH car start battery2 20AH motorcycle battery 2 to 3 in parallel3 2S 5S 4000mah Lithium ion battery with discharge above 30CPackage Contents1 x Main Circuit Board1 x Buzzer2 x Input Wire2 x Output Line with Welder PenNote Users need to provide their own 12V battery power supply welding current about 100A 200A for the common 0 1mm 0 15mm nickel plating sheet welding ease Please make sure your battery can have more than 100A current otherwise it will not be able to solder There might be little error of size for manual m
