A welding machine PCB board (printed circuit board) refers to the circuit board inside a welding machine that controls the machine's functions and coordinates the various electrical processes necessary for welding. The PCB acts as the central hub for managing the power, signals, and connections between the different components of the welding machine, such as the power supply, transformers, sensors, and controls.

Welding machines, including arc welders, MIG/TIG welders, and inverter welders, often rely on PCBs to regulate settings like voltage, current, frequency, and duty cycle, ensuring the machine operates correctly and efficiently.
