Explore plasma cutting alternatives beyond standard compressed air in this 15-minute instructional video that tests nitrogen and argon gases with a 45-amp handheld plasma torch. Learn the fundamental differences between air, nitrogen, and argon for plasma cutting, including their respective advantages and disadvantages for different applications. Discover proper air requirements including PSI, CFM specifications, and the importance of dry air to prevent oxidation during cutting operations. Watch comparative testing on three common materials - carbon steel, aluminum, and stainless steel - examining cut quality, speed, dross formation, and edge characteristics with each gas type. Understand when nitrogen produces superior edge shine and reduced dross compared to air, particularly on aluminum and carbon steel applications. Examine why argon is primarily suited for marking rather than cutting due to its slower cutting speeds, despite producing clean results. Compare final results across all three gases, analyzing cut speed, kerf width, dross levels, and weld-ready edge quality to determine optimal gas selection. Gain practical insights into equipment setup using a Radnor 45-amp plasma cutter with drag tip configuration, and receive expert recommendations for choosing the most appropriate gas for specific handheld plasma cutting scenarios based on material type and desired cut quality.
