Cut some 2 inch steel tubing today.
As big and bad as it is, plastic stops it like Kryptonite. We have to pre-burn the thin protective plastic film off of metal before cutting or it won’t cut the metal. Even a plastic or paper label on the back side of metal might cause it not to completely cut the metal.
Wow, That surprises me.
Took some googling but the prices seems to start around 20k , for a borring flat one too.
