This washer plays a pivotal role in the assembly of the MIG gun front end, specifically within Q-Gun, S-Gun, and T-Gun series torches. It is engineered to sit securely behind the gas diffuser and nozzle, providing a critical barrier against radiant heat and spatter accumulation that can damage the neck insulator.<\/p>\n<h2>Technical Specifications<\/h2>\n<p>Manufactured from high-temperature resistant composite materials, the Q402 shock washer is built to withstand the harsh thermal cycling inherent in industrial welding environments. It ensures the concentricity of the contact tip and nozzle by providing a stable seating surface. This 5-pack (Q402-5) allows for regular maintenance schedules to be adhered to without downtime. The washer is compatible with all standard Centerfire gas diffusers and nozzles.<\/p>\n<h2>Application and Compatibility<\/h2>\n<p>This shock washer is essential for maintaining the dielectric strength of the torch head assembly. It prevents the nozzle from electrically shorting to the contact tip or diffuser in the event of insulator failure. It is a direct replacement for the OEM Bernard Q402 part and fits seamlessly into any setup utilizing the Centerfire front-end platform. Regular inspection and replacement of the shock washer are recommended during nozzle changes to ensure optimal gas flow and arc stability.<\/p>\n","protected":false},"excerpt":{"rendered":"Product Overview The Bernard Style Q402-5 Heavy Duty Shock Washer is a specialized replacement component designed for the Bernard Centerfire consumable system.
