The ESAB 20755 Insulator Assembly is a high-dielectric component engineered for mechanized PT-15 and PT-15XL plasma cutting torches. It serves as the primary dielectric barrier within the torch head, electrically isolating the cathode (electrode) from the anode (nozzle) and other conductive torch body components to prevent internal arcing and catastrophic damage to the torch body.
Features
High dielectric strength for electrical isolation in high-voltage environments
Superior thermal stability for high-energy plasma arc cutting
Ensures structural concentricity between the electrode and nozzle for arc formation
Resists tracking and carbonization common in high-voltage plasma environments
Prevents current leakage to the shield cup or operator handle
OEM precision alignment for optimized cut quality, angularity, and consumable life
Maintains rated duty cycle and performance characteristics of PT-15XL systems
