200dx questions

[budracer1]

Ok Ive got a few questions, im noticing what seems like excessive cleaning action. I have the ac balance turned all the way left but im getting a pretty wide etched zone on all butt welds and lap welds but its not quite as bad on inside or outside corner joints, so that leads me to believe its either me or gas setting or may just be nature of the beast.

Here are some pics of what i am referring to.

Also I would like to know if there are any plans to adapt the newer pedal to the 200dx which would include an update to adjust voltage for pedal using the onscreen display...not bitching (I knew it when i bought it) just asking.

Thanks JB
