摘要：Electric arc welder () performs a given weld process with selected current
waveform performed between electrode () and workpiece (). Welder () includes acontroller with a digital processor (), sensor () for reading instantaneous weld current,and circuit () to convert the instantaneous current into a digital representation of thelevel of instantaneous weld current. Digital processor () has program circuit () toperiodically read and square the digital representation at a given rate, register () forsumming a number N of square digital representations to give a summed value, and analgorithm () for periodically dividing the summed value by the number N to provide aquotient and then taking the square root of said quotient to thereby digitally constructrms signal () representing the root mean square of the weld current.
