Variable Balance – Control Deposition

By setting the correct wave balance (that is, the ratio between positive and negative waveforms), the operator is able to work faster and fill the weld joint with fewer passes. The Power Wave AC/DC 1000™ has wave balance range of 25% to 75%.

The more positive the wave, the more penetration.

The more negative the wave, the greater the weld deposition.

DC Offset (Variable Amplitude) – Control Penetration

Wave amplitude and the duration of positive and negative cycles are independently adjustable, so the operator can obtain deep/shallow penetration and higher/lower deposition rates, depending on the application. The Power Wave AC/DC 1000 has the widest range of vari- able amplitude, or DC offset, (-25% to 25%) in the industry.

Increasing the positive amplitude (offset) increases penetration.

Increasing the negative amplitude (offset) decreases penetration.

Multi-Arc Environment

In a multiple arc welding, as many as five arcs operate in a single weld puddle. Changes to the positive/negative polarity phases and/or cycle balances of the AC waveform enable the operator to control deposition rate, penetration and travel speed without a change in voltage or current settings. Using the Power Wave AC/DC 1000 in a multi-arc system can increase your weld speeds, yield higher quality welds and improve efficiencies.

Phase Relationship – Controlling Arc Blow

In a multi-arc environment, arc interaction plays an important role in the behavior of the weld. Two positive electrodes pull together, as do two negative electrodes, while a positive and negative repel each other, causing arc blow. The Power Wave AC/DC 1000 balances the "push" and "pull" of the multi-arc relationship using phase shifting to prevent arc blow.

By phase shifting the AC waveforms, the amount of "push" and "pull" of the arc interactions can be bal- anced using alternating current to avoid arc blow.
