Premature electrode burn-back and erratic arc transfer cause inconsistent cut quality and costly workshop downtime during manual or automated plasma cutting. The Trafimet Compatible Plasma Electrode (MPN: PR110) delivers a stable arc transfer and uniform energy density to eliminate thermal degradation and preserve cutting speed on heavy-duty fabrication jobs.
What’s In the Box
Benefit-Driven Technicals
-
Hafnium Insert Core: Provides high thermal resistance to prevent premature pit erosion during high-amperage pilot arc starts.
-
Precision-Machined Threading: Guarantees direct seating into the torch head for maximum electrical conductivity and minimal voltage drop.
-
Optimised Heat Dissipation: Rapidly transfers heat away from the torch tip to protect the swirl ring and nozzle during extended duty cycles.
-
Standardised PR110 Geometry: Ensures a direct OEM drop-in fit for seamless consumable replacement without re-calibrating cutting height or parameters.

EWS Expert Note
Always inspect the pit depth of your PR110 electrode before beginning a critical production run. When the center hafnium emitter burns back by more than 1.5mm, replace the electrode immediately; running a deeply pitted electrode causes arc instability that will quickly destroy the cutting nozzle and torch head threads. Ensure air filtration systems deliver clean, dry, oil-free compressed air to double the usable consumable life.

Technical FAQs
Q: Are these PR110 electrodes fully compatible with my existing Trafimet torch setup?
A: Yes, the Trafimet PR110 electrode engineered by EWS is a direct-fit replacement designed specifically for Trafimet SK25, SK25K, SK30, SK35K, and S45 plasma torches. They install directly into the torch head without needing specialised adapters or modifying your standard swirl rings and cutting nozzles.
Q: What is the maximum cutting output limit for these PR110 plasma electrodes?
A: These industrial-grade electrodes are optimised for air plasma cutting torches operating within a 20A to 40A range. Exceeding 40A amperage thresholds causes accelerated hafnium erosion, resulting in severe arc divergence, poor cut bevel angles, and potential thermal damage to the surrounding nozzle tip.
Q: How do compressed air quality standards affect the service life of PR110 electrodes?
A: Moisture, oil, or particulate contamination in your compressed air line drastically accelerates electrode deterioration. Clean, dry air complying with ISO 8573-1 class 1.4.1 prevents oxidation of the hafnium core, ensuring consistent arc striking, maintaining UKCA/CE compliance safety standards, and preventing arc tracking across internal torch insulation.
