These machines use a lot of power and are often hard to move because they are heavy and big. To fix these problems, this project shows how to design and build a compact, energy-efficient inverter-based welding machine that gives a stable and controllable welding current. The system uses high-frequency inverter technology with IGBT-based switching, PWM control, and a ferrite-core high-frequency transformer to change AC input into a regulated DC welding output. The design makes the arc more stable, cuts down on power loss, and cuts down on output ripple. The prototype that was made successfully supports more than one welding process, like Tungsten inert gas (TIG) and stick welding, and is more efficient and portable. The experimental results show that this welding machine is more efficient, smaller, lighter, and more stable than other welding machines. The system is a cheap and reliable solution that works for both home and industrial use. Key points:- • Conventional welding machines are bulky, inefficient, and hard to handle • Proposed system is compact and energy-efficient • Uses IGBT, PWM, and high-frequency inverter technology • Provides stable arc, low ripple, and reduced power loss • Supports TIG and stick welding • Achieves high efficiency, portability, and better performance • Suitable for industrial and domestic useen-USProject Report
