Cros Arc plasma spares need matching carefully to your torch and machine if you want clean cuts and sensible consumable life. Electrodes, nozzles, swirl rings and shields are all wear items – once cut quality drops or piercing takes longer, they’re usually the first place to look. Always choose the correct amperage rating and torch type (hand or mechanised) and avoid mixing patterns across brands. If you’re unsure, BWS engineers can cross‑reference your Cros Arc model and current settings to specify the right kit.
