PT31 Electrode Nozzle Plasma Cutting Machine Consumables Components

• Describe

  PT31 electrode + nozzle product description

  1. Core functions and compatible models
  Functional positioning: consumable components designed for plasma cutting machines. The electrode is responsible for conducting electricity to stimulate the arc, and the nozzle compresses the airflow to form a high-energy plasma beam to achieve metal melting.
  Core adaptation:
  Main models: Wenzhou 40/LGK-40 series plasma cutting machines (domestic main models);
  Compatible expansion: PT-31 cutting gun, K-40 and other similar equipment.

  
  2. Detailed explanation of specifications and parameters
  Parameter item Specification details Electrode material Copper substrate + imported hafnium wire tip (high temperature resistant and ablation resistant) Nozzle process Precision nickel-plated brass/copper (aperture accurate to ±0.05mm) Package configuration Electrode + nozzle standard pairing (some include diverter and protective cover)

  
  3. Performance advantages Efficient cutting: Hafnium wire electrode is resistant to arc impact, with a lifespan increased by 30%, and supports continuous cutting of stainless steel/carbon steel; Nickel-plated nozzle resists metal splash adhesion and reduces the frequency of cleaning. Flexible adaptation: Standard type (length adapted to conventional gun head) and extended type (deep seam cutting scene) are provided; Interface is standardized (PT-31 thread) and supports quick replacement.

  
  4. Purchase and Use Guide
  Model Matching: Look for the "Wenzhou 40" or "PT-31" logo to avoid confusion with SG55, etc. Maintenance Recommendations: Replace the electrode hafnium wire when it is 50% depleted, and replace it immediately when the inner wall of the nozzle is carbonized; Use a ceramic protective cover to prevent short circuits and improve safety. Note: Non-original accessories can easily lead to unstable cutting, so it is recommended to purchase through authorized channels.
