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
