An inverter welder is a type of welding machine that uses an inverter to provide power to the welding process. Inverter welders are generally smaller, lighter, and more portable than traditional welding machines, and they offer a number of advantages over traditional welding technology. They are more energy efficient, as they use a high-frequency switching power supply to convert AC input power into the DC power required for welding. This allows them to use smaller, more efficient transformers, which reduces their size and weight. Inverter welders also have faster response times and can be more easily adjusted to different welding conditions, making them well-suited for a wide range of welding applications.
