Oxy-acetylene torch to cut and clean scrap metal?

I know this doesn't answer your question but I use a plasma cutter. I started out with a junk Everlast. After 2 episodes of dealing with warranty work I got rid of it and went with a Hypertherm. I am really impressed/happy with it.

I am also set up to go mobile with a generator and compressor. Generator does okay. Compressor really lacks. Wishing I had gone with a bigger unit. Shop compressor does fine, it's a Puma 60 gallon upright. Had never heard of Puma, but it was cheap enough I thought why not give it a try. I've been pretty happy with this also.
