One Bad Apple Cylinder Spoils the Whole Bunch
Metal fabricators began reaping the benefits of laser cutting technology as far back as 1965 when they started using it to drill holes in diamond dies. Because of its cutting precision and energy efficiency, laser cutting has many advantages over plasma cutting when cutting sheet metal. And through numerous technical advancements, newer laser machines operating at higher power (6000 watts versus the 1500 watt ratings of early laser cutting machines) have approached plasma machines in their ability to cut through thick materials.
But to realize these benefits, laser cutting machine owners and operators must adopt some key processes and procedures. One set of key processes and procedures involves "assist gas" management. Following sections describe key do's and don'ts about laser assist gas management...including how the old saying One Bad Apple Spoils the Whole Bunch is something to worry about...but can be easily addressed.
