I welded all positions in the shops I worked in including 7018 overhead but on DC. Never welded uphill, always downhill and ran 6011 if doing a bunch of it. This AC rod is a little different.I went auto dark maybe 10 years ago. Will never go back. When welding in the steel plant we had to be able to weld in any position. I still don't like welding overhead. Maybe with one of those fire proof space suits it would not be to bad.
I'd always roll my socks over my bootcuffs and it'd keep slag off my ankles.
