When selecting a demo stick welder, the welding output amperage range is crucial because it determines the thickness and type of materials you can weld. A broader range offers more versatility, letting you handle light repairs as well as heavier fabrication. Demo stick welders typically range from about 5A to 155A, which is suitable for most maintenance, repair, and light industrial tasks. For example, the Lincoln Invertec V155-S provides a 5-155A range, enabling precise work on thin metals and ample power for thicker sections. This flexibility helps buyers match the machine to their specific project needs, and various models offer output ranges to suit different welding demands.
