Looks like it makes a good bend. Your welds should b fine for this project, dosen't look to me like the welds are really under any stress, they more or less just hold things straight and allow the spring to return the wedge. I'm no expert welder either, but looks like you may have been a little cold/ moving too fast. the first thing I always do before I weld is get comfortable, make a dry pass with your welder down the weld and pay attention to your angle/stick out. If you are comfortable for the length of the weld, burn it in.
I'll b interested to see how you like the little press brake, been thinking about getting one myself.
I'd like to think I'm the guy they are talkin about when they say, "he could F%^& up a cannon ball in a plowed field."
