The Everlast trailer-build videos on youtube inspired me to try some plug welds. Drilled a series of holes in 3/32 angle and nested another piece of angle underneath, looked up settings on a MIG calculator, and started welding.

I thought it was going well enough- I was getting the dome recommended in the videos, and was feeling pretty good about the whole deal... then I got a wire wheel after it, and found a dimple on each one.

Did I read somewhere that spatter and the dimple is a sign of too much heat?
