ABSTRACT:
A controller and method for adjusting an output welding parameter of a D.C. electric arc welder for controlling a welding process wherein a welding wire is advanced toward a workpiece while an arc voltage is applied across the advancing wire and the workpiece, the control and method comprise measuring the rate of spatter events and then adjusting the output parameter to maintain the measured rate of spatter events at a selected rate in the range of 10-30 spatter events per second.
