Excellent post freonjoe the reason plasma is safer to use cutting oil contaminated scrap is because the plasma stream uses compressed air to remove the molten metal from the melt zone, whereas an oxygen torch using pure oxygen to burn and remove slag from the cut zone. The oxygen torch will give you a volatile blow back cutting oil contaminated scrap especially if you cut into a pocket filled with oil. Which will happen on large cranes and dozers.
I've lost facial hair more times than I care to remember cutting up heavy equipment.
Says right on your oxygen gauge use no oil.
