Item Details

  • The Hypertherm 420276 is a high-amperage liquid-cooled electrode designed for X-Definition mechanized plasma cutting. It serves as the primary arc initiation and stabilization component for mild steel processing at 220A and 300A. The part features a multi-metal construction consisting of a high-purity copper body for thermal dissipation and a precisely matched hafnium emitter for arc attachment. It is engineered with a hollow milled post and machined step to ensure concentric coolant flow when paired with the required water tube.

Features

  • QuickLock™ Technology: 1/4-turn locking mechanism for threadless installation and concentric alignment
  • Arc Response Technology™: Automatic system response to ramp-down errors to prevent electrode blowout
  • Hafnium Emitter: High-temperature insert matched to 300A power levels for controlled erosion
  • Hollow Milled Post: Internal geometry designed for alignment with water tube and optimized coolant flow
  • Laser Identification: Laser-etched part number and batch code for traceability
  • Automatic Torch Protection: System-level sensing to prevent catastrophic failure from electrode overuse
  • True Hole® Technology Integration: Supports ISO Range 2/3 bolt hole quality in mild steel (3 mm to 25 mm)
  • Vented Water Injection™ (VWI) Compatibility: Supports optimized cutting processes for non-ferrous and mild steel
  • Environmental Compliance: 99.5% recyclable system design
  • Resource Efficiency: Consumable design utilizes 64% less copper per foot of cut compared to previous generations
  • ISO 9001:2015: Manufactured under certified Quality Management Systems
  • Regulatory Compliance: Meets CSA C22.2 No. 60974-1 and ANSI/NEMA/IEC 60974-1 standards
