Patent ID: 8759715

Claim:
A method of arc welding with a cored welding electrode, said method comprising: generating a welding waveform with a waveform period and a root mean square (RMS) level for maintaining a stable short welding arc based on at least said cored welding electrode, said welding waveform having a positive portion and a negative portion, wherein said positive portion has a first magnitude and a first period and said negative portion has a second magnitude and a second period and where said first magnitude and said second magnitude are not the same; and adjusting a wave balance of said welding waveform to maintain said stable short welding arc, wherein said wave balance is a ratio between said first period and said waveform period, and wherein if an absolute value of said first magnitude is greater than an absolute value of said second magnitude then said wave balance is reduced to maintain said stable short welding arc and if said first magnitude absolute value is less than said second magnitude absolute value then said wave balance is increased to maintain said stable short welding arc.
