I think the welds are probably OK. I made multiple passes with the highest amperage setting. I used the same setting and process welding a hook to my tractor bucket which has supported V8's and yanked everything from t-posts to power poles with no sign of breaking. I also used the same setting to repair the upper shock attach fitting on the rear where it is riveted to the frame crossmember and had fractured. I know I got very good penetration there. My spring perches appear to be 1/8-5/32 metal. Essentially, you have a T weld on each outside surface where it meets the axle tube. As I said, I made multiple passes, building up a 1/4 to 3/8" radius fillet.
All that being said, if I ever have to do this again, I'll use the 220V Stick Welder.
