Keep a shop-floor copy of the recommended starting values, then record your tested settings and notes.
Important
These values are starting recommendations. Actual settings vary with the plasma source, torch, consumables, air quality, table motion, material composition, and consumable wear. Verify settings using the manufacturer’s manual and test cuts.
