I own a small manufacturing company and originally bought my PP50 to cut 13g x 1/2" expanded sheet metal as cut off wheels were very inefficient. I've seen you tube videos of plasma cutters slicing through exp metal but I haven't had the same success with mine. I had to revert to using cut off wheels. I hope there is a way to use the PP50 for this though as I do a LARGE amount of exp cutting for the products we manufacture and the cut off wheels are getting expensive.
