I recently purchased a PP256 (last yrs mdl) and, during some pre-purchase discussions with Everlast I had, was told "But if you are welding with the foot pedal, the only thing you are really getting much more with the 250ex (over the 200) is a lower AC start, a little more cleaning range, and 50 more amps. All those other knobs and controls are not used with the pedal."

So, wasn't I surprised when using the TIG w/pedal for the first time, and I rolled-back to OFF the machine followed the downslope settings. It seems to me the Up/Down Slope, Start/End Amps, and All the Pulse functions are in the picture when I use the pedal. I can't figure what it is that's different...

Am I missing something or did I just misunderstand???

I think I've gotten comfortable with most of these parameters, the only thing that still seems somewhat mysterious to me is when/how to determine when I would want to change the Balance & Ratio of the Pulse (I'm leaving them in the middle for now ). Is there somewhere where I can find a good explanation?
