WAVEFORM CONTROL TECHNOLOGY ®<br />
The waveform may be varied to:<br />
• Control Penetration<br />
• Control Bead Shape<br />
• Minimize arc interactions which can cause arc blow<br />

Positive Current Level = Penetration<br />
100% DC+<br />
(traditional)<br />
Cycle Balance = Penetration/Deposition<br />
AC Frequency<br />
Negative Current Level = Deposition<br />
SOFTWARE DRIVEN CONTROL OVER PENETRATION, DEPOSITION RATE AND TRAVEL SPEED<br />
Travel<br />
Speed<br />
• Maximum Penetration • Less Penetration<br />
• Greater Travel Speed<br />
Waveform Control Technology ® capability provides<br />
precise control over:<br />
• AC Frequency<br />
• Balance (Percentage of time in the positive polarity<br />
portion of one cycle)<br />
• Offset (Positive/Negative Amplitude)<br />
