A method and system for adjusting the output voltage applied to a wire electrode during an automatic parameter selection mode in which the rate of advancement and output voltage is automatically determined. A control circuit determines appropriate power parameters in response to at least one configuration parameter. The control circuit generates a power command accordingly based on an expected, or nominal, input voltage. A sensor connected to the control circuit monitors the actual input voltage. If the actual input voltage is outside of an acceptable range, the control circuit scales the generated power command with a scaling factor calculated based on the actual input voltage.
