Welder Frequency. The term "high frequency", when applied to tube welding, can mean anything from 80kHz., to over 800kHz. Although frequency within this range has little direct effect on the width of the heat affected zone, & thus upon the quantity of metal heated, there are several indirect effects which relate to efficiency.
