Steel Cutting N2 vs. O2: To Use or Not To Use, .
04.07.· Typically, the cutoff point where nitrogen is no longer a consideration is at approximately 1/8 in. For example, cutting .080 in steel with oxygen and a 3 kW laser occurs at approximately 200 ipm and requires roughly 65 cfh of gas. On the same laser, cutting with nitrogen, speed remains constant but gas consumption increases to 465 cfh.
