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

?
??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.

??Specification

? Voltage: 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)

?

? Application

?

? 1.36-60AH car start battery
