Abstract
An arc welding control method and apparatus includes a voltage control loop in which a pulsation parameter such as pulse width, pulse amplitude, background amplitude between pulses, or frequency, is adjusted to compensate for deviations in the arc voltage, and a second, slower feedback loop which adjusts a second parameter of the system in order to cause the pulsation parameter to return to a desired value as a result of the effect of the adjusted second parameter on the arc voltage.
