    I have found pulsing GTAW less useful than it is claimed to be. I get headaches from a wide range of frequencies but find very slow frequency useful in restrict in heat input and building weld bead contour. I prefer being fussy about tungsten selection and grind over higher frequencis to tighten the arc plasma (wave balance in a.c.) in tight joints
    Maybe I am too old….old school.
