Abstract
The present invention provides a GMAW control system for balancing wire burnoff rate with wire feed speed at a weld site. A power source applies a pulsed current to the consumable wire. The width of the peak pulse current is calculated and adapted to maintain a constant optimum arc length as selected by the operator. The controller provides a reference voltage to the power source and the power source provides the pulsed current having a magnitude responsive to the reference voltage signal.
