OK, I need help before I pull whats left of my hair out. Harris torch running a #000 tip for 1/8" steel, acet at 5 pounds and oxygen at 20 pounds. When I start the cut I preheat until the parent metal begins melting and then press the cut bar, and here we go. As I move across the parent material, a hole naturally forms where the oxugen is blowing the molten metal away, but once I pass that point, the slag re-joins behind the flame and closes the gap! I never have the piece just fall off with the first pass, I have to go back and melt off enough slag to make fishing weights. What the hell am I doing wrong...Ernie...anybody...?
I've tried a gentle flame, I've tried a roaring inferno, nothing seems to give a nice clean cut.
