Category Consumables & Maintenance

Plasma cutter performance depends on healthy consumables and routine care. Learn the role of the electrode, nozzle, shield, and swirl ring, plus clear signs of wear—hard starts, wider kerf, bevel, top spatter, and double-arcing. Match nozzle size and amperage to material thickness, set correct standoff, and keep air clean and dry (use filters/dryers) to reduce erosion. Inspect O-rings, keep threads clean, and tighten parts to spec—over-torque shortens life. Maintain rated duty cycle, verify PSI/CFM at the torch, and avoid long, undersized extension cords that cause voltage sag. Coil leads loosely, check strain reliefs, and log consumable hours. Keep a labeled spare kit on hand so you can swap parts before cut quality drops.
