WebMay 19, 2009 · While conventional GTAW technology limits AC frequency to 50 or 60 hertz (Hz), new GTAW inverters allow frequency to be adjusted anywhere from 20 to 400 Hz. Frequencies between 80 and 120 Hz are comfortable to work with, increase control of the arc, and boost travel speeds. Setting the frequency from 120 to 200 Hz provides an ideal … WebWhen a large demand is suddenly placed on a rotating electromechanical generator, the generator’s rotational speed slows down. This causes the voltage frequency produced to reduce. Conversely, suddenly removing a large load can cause the generator to speed up until the control systems can adjust.
