220668 plasma cutting electrode

1. Rated Current
• Supports a maximum cutting current of 260A, suitable for industrial-grade cutting requirements for medium-thick plates (such as low-carbon steel, stainless steel)
2. Materials and Structure
• Imported copper base: Ensures high conductivity and heat dissipation efficiency, resistant to high-temperature oxidation, and prolongs service life.
• Hafnium (or Zirconium) wire electrodes: As the core of electron emission, have better resistance to wear than pure copper electrodes (life is increased by 3-5 times)
3. Lifespan and Stability
• Optimized cooling design (such as water-cooled structure) and high-temperature-resistant materials (such as hafnium wire), single electrode continuous working time can exceed 50 hours (requires a pressure of 0.4 MPa or above).
• Defect Warning: If the hafnium wire at the center of the electrode is consumed by 2.5 - 3mm or there is an abnormal arc sound response, replace immediately
