I've never run a welder with any auto settings but the way I set mine up is as follows:
1. Select a suitable power rating for the material .
2. Take a scrap piece of the material you intend to weld and whilst laying down a bead, adjust the wire feed until you find the sweet spot (listen to the weld as described above). Adjust the wire feed whilst welding. Don't start, stop, adjust, start etc.
The wire feed will affect the penetration of the weld, not just the voltage. Keep the wire stick out short and run the wire at the front of the puddle. Practise, practise, practise!
