Filling is a breeze once you get the settings right. You can fill a panel easy enough using a copper backing plate but I doubt you have access to the areas you are filling.
Small beads around the edges, let cool and then return. Get the edges close, build a "bridge" and fill the gap in a circular bead.
If you are using fluxcore then be sure to hit the bead after each pass with a wire brush to get a good solid weld.

Mike,
Thank you for the advice. I am using .030 wire, with standard 75/25 Ar/CO2 gas. Just curious, how does decreasing gas flow affect the weld? I will be able to access a good deal of the backside of the welding I am doing to put on a copper plate. See pics in next post...
