If a job shop supplies metal parts that are to be powder coated or welded, the customers likely require that those fabricated parts have no oxidized edges. That requirement forces the job shop to cut with nitrogen, which doesn't leave an oxidized edge like oxygen. Unfortunately, cutting with nitrogen is expensive because much more nitrogen is consumed when compared to oxygen to perform similar cuts. This situation led a metal fabricator to investigate nitrogen generation systems. This is his tale.
