Do you find the preset settings to be to your liking for the most part?
How is the polarity switched?
The presets are nice, but I immediately adjusted them. The preset is a good starting point, it remembers where you left off in any mode. Its a good thing because a beginner can step up, and an experienced welder can change up. You can always go back to default. Polarity is done is done by the flick of a switch, to a different mode. Pulse is awsome.
