Abstract
A welding system configured to eliminate effects of arc blow in a welding operation. The welding system comprises welding circuitry, preheat circuitry, and control circuitry configured to switch the welding circuitry and the preheat circuitry between power levels asynchronously during the welding operation. The control circuitry configured to switch the welding circuitry and the preheat circuitry between power levels asynchronously such that the preheat circuitry is switched to the second preheat power level when the welding circuitry is switched to the first welding power level and the preheat circuitry is switched to the first preheat power level when the welding circuitry is switched to the second welding power level.
