The power supply output, measured in amperage, determines the tru weld stud welder's capability to handle different stud sizes and thicknesses. Higher amperage models, like the 3000A TW6900, are suited for large diameter studs and demanding applications, while lower amperage units like the TW4400 (suitable for up to 5/8″ studs) or the TWi-250 (for smaller CD studs) are ideal for lighter work. Tru-Weld’s range of power outputs ensures you can choose a welder that matches your required stud diameter and application intensity.
