Hazards of Overdue Replacement of Plasma Consumables
1. Significant Deterioration in Cutting Quality
Loss of cutting precision: Overused electrodes/nozzles suffer from thermal degradation, causing arc focus deviation. Cut perpendicularity errors may exceed 0.5mm, requiring rework or scrapping precision components.
Accelerated surface oxidation: Failed gas distributor seals create turbulent shielding gas flow, inducing oxidized layers on cut edges and raising post-processing costs.
2. Equipment Stability Risks
Arc fluctuation and system overload: Worn eddy current ring assemblies disrupt magnetic field generation, triggering high-frequency arc oscillations that may cause cutting head misalignment or circuit board burnout.
Cooling system cascade failure: Severely degraded electrodes elevate plasma gas temperatures, impairing water cooling system efficiency and accelerating pump wear.
Continuing to use plasma consumables beyond their recommended lifespan may seem to save on replacement costs, but it actually reduces operational efficiency, compromises cutting quality, and ultimately increases overall production expenses—the disadvantages far outweigh any perceived benefits.
