Component Specifications

Definition
A consumable electrode component in a plasma cutting torch that initiates and sustains the plasma arc by conducting electrical current to the workpiece, typically made of high-temperature resistant materials to withstand extreme thermal and electrical conditions during metal cutting operations.
Working Principle
The electrode creates an electrical circuit with the workpiece through a pilot arc, which ionizes gas to form a plasma jet for cutting. It transfers high-frequency current to initiate the arc and maintains conductivity while resisting erosion from high temperatures and plasma gas flow.
Materials
Copper alloy with hafnium or tungsten insert, silver-plated for enhanced conductivity, with ceramic insulator housing.
Technical Parameters
  • Length 25-50 mm
  • Diameter 3-6 mm
  • Insert Type Hafnium/W2% Thorium
  • Thread Type M5-M8
  • Voltage Range 100-400 V DC
  • Cooling Method Gas or liquid
  • Current Rating 20-200 A
Standards
ISO 9013, DIN 2310, AWS C5.2
