Welding vertically stainless steel

This blog is about practical welding advices. In that shell, I would like to ask all welders who weld vertically stainless steel about methods that avoid high welds. I think that welding stainless vertically is difficult since it is a "darker" weld and a small amperage difference from ideal cause high weld or "grapes". I personally like to test first and use a smaller rod to have more control. Moreover, I increase horizontal wave a little and I try to keep the rod as close to the piece as possible. However, I still think amperage set up is critical and the tolerance would be about 3-5 amps. So, if you can provide any other advice for welders welding vertically stainless steel, I would highly appreciate it.
