The output amperage range is crucial because it defines the welder’s ability to handle thin materials and heavy-duty work alike. A broader range allows for finer control and more application flexibility—lower amperages for sheet metal and higher for thick structural steel or gouging. For example, the Lincoln Power Wave S500 offers a robust 5-550A range, ideal for demanding industrial jobs, while the Power Wave S350 provides 5-350A, suitable for precision work and general fabrication. Having options from 5A up to 550A across different models ensures users can match output to their welding needs.
