The Radnor 64005617 (Ref No. 54N01) is a TIG torch gas lens insulator and gasket designed for 3-Series torches. It functions as the interface between the torch body and the gas lens, providing a physical seal to maintain shielding gas purity and electrical insulation to prevent high-frequency current leakage.
Features
Gas Lens Seal: Seats between the torch head and gas lens to prevent atmospheric air from entering the gas stream
Dielectric Strength: Provides electrical insulation to prevent high-frequency arcing to the nozzle or torch head
Thermal Stability: Maintains structural integrity under extreme heat of continuous TIG welding
Concentrated Gas Flow: Ensures nozzle seats concentrically to maintain laminar flow benefits
Chemical Resistance: Resists degradation from shielding gases and industrial contaminants
Anti-Arcing: Prevents current leakage during high-frequency starts
Extended Stick-out Support: Facilitates laminar flow allowing for further tungsten electrode extension
Brand Compatibility: Weldcraft, CK Worldwide, Lincoln Electric, Miller, ESAB, TecTorch
Component Compatibility: Used in conjunction with nozzle insulator 18CG (300HS) for gas lens collet bodies; compatible with CK Worldwide 3 Series heat shield
