Thanks. That confirms my experience. There were two near-identical HF90's at the time and I chose the one where its two heat choices were near identical. That was a mistake. With .030 wire I characterized the two settings as Too Hot and Way Too Hot. Like you, I found it worked best with .035.
Come to think of it, this was the welder that came with unusable flux core wire. It would only spit globs and there was a flood of customer return 'near new in box' HF90's on Ebay at the time from a single resale vendor, until they cleared that batch of wire. I replaced the wire immediately, after reading about the wire issue. Big improvement, now it would weld beads. 'Some Assembly Required' to make a HF tool work per its specs was the norm back then.
I suspect that was the wire that spawned the famous customer recommendation to throw out the wire that came with the welder and replace it with Lincoln wire.
