Abstract
A method of arc welding with a cored electrode comprising creating a positive waveform with a first shape and having a first time; creating a negative waveform with a second shape and having a second time; making one of the first and second shapes greater in magnitude than the other of the shapes; and, adjusting the percentage relationship of the first and second times so the time of the shape with the greater magnitude is substantially less than the time of the other shape.
