They pretty well covered it. I bought some of that very rod recently
at HF. But have not used it yet.
DC+ at even 25 amps seems to work for me with a Maxstar 140 for 1/16"
rod. But I've never yet tried this particular HF rod.
If you attempt to weld metal that's too thick with 1/16" rod, it'll
tend to just puddle up but not bond. That's the only situation where
I've ever stick welded and didn't get a strong bond. I recently
repaired a neighbor's mower deck with 3/32" 6013 rod at about 60 amps.
For pretty thin stuff I generally try 3/32" first. Then, if it burns
through I go to the 1/16" rod.
Works for me.
