Welding ==> Oxygen Vs Plasma Cutting

UpUp


The pictures below show a 3/4" mild steel plate. On one end, I cut it with Oxy/Acetylene while visiting my friend. On another end, it was cut with a plasma cutter. The plasma cutter that I have is a big ugly three phase machine called Hypertherm Max 100. I am sure that I did a lousy job on both ends, but the plasma side is considerably smoother.
