It’s that unwanted buildup of metal along the bottom edge of your parts that leaves you reaching for a grinder when the cutting is finished. A little dross might not seem […]
Why CNC Plasma Air Pressure Matters More Than You Think You can have your amperage, cutting speed, and torch height perfectly dialed in and still get terrible results if your compressed air supply isn’t doing its job. One of the most overlooked variables in CNC plasma cutting is air pressure. More specifically, it’s the difference […]
How Amperage, Cut Speed, and Tip Size Work Together in CNC Plasma Cutting A plasma cutter has a lot of settings, but three of the most important are closely connected: Amperage Cutting speed Tip size The mistake is treating them as three independent settings. They are a system. If you change amperage without considering the […]
