The Shock Washer 402-5 Tregaskiss Style is a critical component designed for the maintenance and repair of 300A and 400A Tregaskiss-style MIG welding guns. This aftermarket replacement part is engineered to replicate the dimensional specifications and performance characteristics of the original equipment manufacturer (OEM) part number 402-5. Manufactured from high-grade aluminum, this washer provides the necessary mechanical spacing and support required within the torch neck assembly.
In a MIG gun assembly, the shock washer plays a vital role in seating the nozzle and diffuser correctly. It acts as a buffer that absorbs mechanical vibration and helps maintain the concentricity of the consumables. Furthermore, it assists in the electrical isolation of specific torch components, preventing unwanted arcing or short circuits that could damage the equipment or compromise weld quality. The aluminum material is selected for its excellent strength-to-weight ratio and its ability to withstand the elevated temperatures typical of industrial welding environments without deforming.
Proper maintenance of the torch head is essential for consistent wire feeding and gas coverage. A worn or missing shock washer can lead to loose components, gas leaks, or misalignment of the contact tip. This replacement part ensures that maintenance personnel can restore the gun to optimal operating conditions quickly and cost-effectively. It is compatible with a wide range of air-cooled MIG guns rated for 300 to 400 amperes, making it a versatile stock item for workshops utilizing Tregaskiss-style equipment.
Installation is straightforward, requiring disassembly of the front-end consumables. The washer sits securely at the base of the neck or diffuser assembly, providing a stable platform for the nozzle. Its precise fitment ensures that it does not interfere with gas flow or wire travel, maintaining the high standards of performance expected from professional welding equipment.
