Abstract: Abstract: The present invention provides a microcontroller-based portable spot welding system that utilizes a microcontroller, designed to carry out welding functions that are highly accurate, safe, and economical. The system includes a custom-built transformer that can transform a primary voltage of 230 V AC into secondary voltage of around 4 V AC, a controller microchip for timing purposes, and a switch with optoisolation capability to control power supply safely. The microcontroller, preferably an ATmega328P, allows the user to set the required time for which the welding process should be performed via input circuitry like a potentiometer. The microcontroller will generate a pulse when triggered by a switch and control the TRIAC via the opto-isolator, allowing it to regulate the power delivered to the transformer for a specific amount of time. The device uses a seven segment display with a shift register to inform the user of their actions, a cooling system using MOSFETS to manage heat dissipation, and an RC snubbed to protect the switch from any voltage spikes. The invention is meant to be small and portable, allowing its use in laboratories, small workshops, and even prototype testing facilities. Through the combination of all these advantages in one product, the device presents a practical substitute to expensive and bulky welding machines.
