Lincoln Electric Introduces Inverter-Based Power Wave AC/DC 1000

I thought this tidbit was interesting...

CLEVELAND, May 26 /PRNewswire/ -- The Power Wave AC/DC 1000 inverter power
source from The Lincoln Electric Company is designed as part of a modular
welding system for single or multiple arc applications targeted at submerged
arc customers with these objectives: increased productivity, lower operating
costs, improved quality and greater production flexibility.

The machine is rated at 1000 amps for AC or DC. Each welding arc may be
driven by a single machine or by a number of machines in parallel. For
example, two machines can be used to produce up to 2000 amps at 100 percent
duty cycle. At the same time, each Power Wave 1000 achieves a 95 percent
power factor with 86 percent efficiency for lower operating costs.

The Power Wave AC/DC 1000 produces a variable AC output, as well as
straight DC+ or DC- output. No hardware configuration changes are required.
These software driven capabilities allow for unprecedented welding performance
in multi-arc applications typical of high quality welding in pipe mills,
pressure vessel applications or structural steel fabrication.

The Power Wave AC/DC 1000 takes advantage of Lincoln's Nextweld(TM)
Waveform Control Technology(TM), which uses electronic regulation circuitry to
control and shape the output waveform. Using Waveform Control Technology(TM),
welding waveform parameters can be tailored to the application.

The AC waveform can operate at any frequency between 0 and 200 hertz with
a single knob. Dialing in the frequency aids in stabilizing the arc. Also,
the amplitude and duration of the positive and negative cycles are
independently adjustable, delivering greater control of bead shape, higher
deposition rates and lower heat inputs.
