Basic High Frequency Inverter Power Supply - 1

High Frequency Inverter Welders HF2 is a 2 KHz, three-phase, high frequency inverter welder designed for precision joining of small parts. High speed (250 ms) digital feedback automatically controls weld current, voltage, or power, ensuring weld consistent, repeatable welding, and has proven to extend electrode life in many applications by a factor of five or more. A selectable weld energy limiting feature also contributes to repeatable welds and high nugget quality. The optional built-in Weld Sentry® weld monitor is capable of sophisticated weld data gathering and SPC computations and reporting. KEY FEATURES • Constant current, voltage or power control modes TYPICAL APPLICATIONS • High weld repetition rates • Spot, braze and seam welding applications • Graphical and alpha-numeric user interface Seam welding Capacitor to lead frame • I/O communication ports for factory installation • Small transformers facilitate easy integration • Optional built-in Weld Sentry with SPC RESISTANCE WELDING
