Looking at your basic setting, you have too much cleaning for the average weld. You may experience some loss of arc stability and DEFINITELY have an issue with the tungsten getting too hot at about 70% DCEP. I'd recommend turning it down to about 30%-35% to start. That gives much better penetration and is sufficient for arc stability. If you are using it at 70% and find it is necessary to get good welds, make sure you have the torch hooked up to the negative terminal. This will cause the setting to be reversed, and cause all kinds of frustrations.
