Abstract
The invention described herein generally pertains to a system and method related to reducing magnetic arc blow by adjusting a current welding waveform that is used to create an arc between a workpiece and an electrode. The invention can provide a welder system that includes a component that detects an amount of magnetic field related to arc blow, wherein a controller can adjust the current welding waveform to reduce the amount of magnetic field related to arc blow. In an embodiment, the welder system can utilize the current welding waveform with a first waveform portion that delivers a first amount of energy to the workpiece and a second waveform portion that delivers a second amount of energy to the workpiece. A controller of the welder system can be configured to adjust the first waveform portion or the second waveform portion to equalize, within a tolerance, the first amount of energy and the second amount of energy.
