Squarewave vs. Advanced squarewave vs. Soft squarewave vs. ...

[taylorkh]

My Dynasty 200 DX offers Advanced squarewave, Soft squarewave and Sine wave with square transitions. Miller's Selecting a TIG Welder Q&A http://www.millerwelds.com/resources...s-and-options/ says that Squarewave is

Squarewave technology shortens the switching time between EN and EP so that the welding machine has sufficient "push" to drive the arc through the zero crossing and then re-establish the arc in the opposite polarity.

and that Advanced Squarewave

Advanced squarewave technology switches the weld polarity thousands of times faster than a conventional squarewave machine, dramatically improving arc starts and arc stability. It also permits more precise control over the weld puddle, bead width and penetration by adjusting output frequency and extending balance control.

Looking at the diagrams on page 6 of the TIG Buyers Guide http://www.millerwelds.com/pdf/TIGBuyersGuide.pdf...

Do any of these waveforms look like the original Squarewave? If not, does anyone have a picture of what the original Squarewave looked like?

TIA,

Thanks Ed Broccoli1,

I have that document printed out. I need to read it cover to cover again. So it looks like the traditional squarewave is now referred to as "soft squarewave". I guess it is easier to sell a machine with the new soft squarewave rather than the old/original squarewave
