From the Miller welder website.

"Offering exceptional arc characteristics for different electrodes and
joint designs, the Trailblazer 302 Diesel features four preset DIG
settings. Providing combined DIG and Process switch, along with preset
DIG settings, offers simple set up without the complication of multiple
switches. The four preset DIG settings include: soft arc and smooth 7018
performance, medium-soft driving arc, medium-stiff driving arc and
driving arc such as pipe welding."

About the Miller Maxtar 200.

"DIG control allows the arc characteristics to be changed for specific
applications and electrodes. Lower the DIG setting for smooth running
electrodes like 7018 and increase the DIG setting for stiffer, more
penetrating electrodes like 6010."

Miller Inverter power sources

"Dig control for Stick welding. Dig control prevents the electrode from
sticking when the arc gets too short. This is helpful for an open-root
pass or tight fit-up work and aids in arc initiation."

I am not sure electrically what is changed when you change the DIG
setting, but you can see above examples of how the DIG control is
supposed to affect the welding arc, apparently by affecting the
penetration and tendency to stick. I have heard of this before. As far
as I know it affects stick welding only, but I could be mistaken.
