Understanding the Basics of Inverter Welders
The Evolution of Welding Technology
Inverter welders have revolutionized the welding industry with their efficiency, portability, and versatility. These machines use advanced inverter technology to convert AC power to DC power, which is then used to create the high-temperature arc required for welding. To understand how inverter welders work, it’s essential to have a basic understanding of welding technology and the different types of welding machines available.
In the past, welding machines relied on transformers to convert AC power to DC power. These transformers were large, heavy, and often produced a lot of heat, making them impractical for portable use.
