Abstract
A welding apparatus having a waveform compensation device, a power section coupled to the waveform compensation device which generates a welding waveform in accordance with a signal from the waveform compensation device, and a frequency detection device which detects at least one of a voltage, current and power of a welding arc and determines a shorting frequency of the arc. The waveform compensation device adjusts at least a portion of the welding waveform based on an output from the frequency detection device.
