I thought I would update more practice shots. I was 90 amps 3/32 7018. The weld looked good but the slag was really hard to remove. I'm not sure why the slag was so hard to remove. I thought it was a sign that my weld is still too cold. I really tried to keep a short ARC and move side to side.

Rebar is typically a low-grade of steel all the extra impurities can make it harder to chip off the slag.
I have more questions than answers

It's my experience if the slag is tough to remove, your arc is too long. Trying to keep a tight arc and doing so are two different things. Rub the base metal gently and you'll be sure to have a tight enough arc.

I hadn't stick welded in years until lately and this was my second string with 7018 1/8 inch rod don't recall amps but I believe 125 I was satisfied with this run. I really need to practice vertical.
