Product Detail

Core parameters and performance

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.

Frequently Asked Questions

What is the maximum rated current for this electrode?

The electrode supports a maximum cutting current of 260A, which is ideal for industrial-grade cutting requirements.

Which materials are best suited for cutting with this electrode?

It is highly suitable for cutting medium-thick plates, particularly low-carbon steel and stainless steel.

Why are imported copper and hafnium wire used in the structure?

The imported copper base ensures high conductivity and heat dissipation while resisting oxidation. The hafnium (or zirconium) wire acts as the core of electron emission and provides 3-5 times better wear resistance compared to pure copper.

How long is the continuous working lifespan of a single electrode?

The continuous working time can exceed 50 hours, provided there is an optimized cooling design (such as a water-cooled structure) and the operating pressure is maintained at 0.4 MPa or above.

What are the warning signs that indicate the electrode needs immediate replacement?

You should replace the electrode immediately if the hafnium wire at the center is consumed by 2.5 to 3mm, or if you detect an abnormal arc sound response during operation.
