AC and DC output polarity affect the types of electrodes you can use and the quality of your welds. DC output is preferred for smoother, more stable arcs and is compatible with a wider range of electrodes, while AC is useful for welding magnetized metals or certain specialty rods. Some machines, like the Idealarc 250 Stick Welder, offer both AC and DC for maximum flexibility, while others focus on DC for portability, such as the Sprinter 180Si. A range of options is available, so you can choose a welder that aligns with your project requirements.
