Output current (amperage) is crucial because it determines the thickness of material you can weld and the speed at which you can work. High amperage machines are ideal for heavy fabrication and thick plate welding, while lower amperage settings offer greater control for thinner materials or precision work. Sub arc welder in this category offers a broad range: for example, the Lincoln Factory Demo Idealarc DC-1000 delivers 150-1300A DC, the Lincoln Idealarc AC1200 offers 200-1500A AC, and the Lincoln IDEALARC DC-1500 goes up to 1500A. This range allows users to select equipment tailored to both high-volume production and precision applications, ensuring optimal results for diverse welding needs. Many models provide both high and low amperage options, giving customers flexibility for a wide variety of projects.
