Ed,

The wave forms are AC only, the waveform buttons are disabled when you are in DC, so there is no pulse shaping.

There are the 3 different AC waveforms that I listed. Sine, advanced and soft. ( the 210EXT does not have the independant amplitude setting of the 250EXT, The 250EXT does not have the waveforms of the 210EXT )

Pulsing on this welder just switches from high to low amperage at a specified rate in AC or DC,..... EXCEPT for the Double pulse option.

Double pulse uses the set AC wave form the high amperage part of the pulse, and DC for the lower amperage part of the pulse. It's something I will have to use more to figure out what the best applications are.

All these settings are like having extra tools in your tool belt, you are going to use 1 or 2 of them most of the time, the others will be used much less, but they will be very handy when they are needed.
