The Generic 401-4-38 Tregaskiss Style MIG Nozzle is a precision-engineered consumable designed to meet the rigorous demands of industrial welding environments. Developed as a direct replacement for the standard duty Tregaskiss 401-4-38, this nozzle offers seamless compatibility with 300 Amp and 400 Amp Tregaskiss MIG guns, widely used in robotic and semi-automatic welding applications. Its construction utilizes high-grade copper alloy, ensuring optimal thermal conductivity and resistance to heat buildup during prolonged welding cycles.
This specific model features a 3/8-inch (9.5 mm) bore diameter, making it suitable for applications requiring focused gas coverage or access to tighter joints where larger nozzles might cause obstruction. The nozzle is designed with a significant 3/8-inch tip recess. This deep recess configuration is particularly advantageous for protecting the contact tip from radiant heat and reducing the accumulation of spatter on the tip face, thereby extending the lifespan of your front-end consumables. It is specifically engineered to fit over the 404-3 gas diffuser and secure onto the 402-3 nozzle retainer, ensuring a stable and leak-free gas shielding environment.
Maintenance and downtime are critical factors in production efficiency. The slip-on design of this nozzle allows for rapid removal and installation without the need for threaded connections that can seize due to thermal expansion or spatter. This friction-fit mechanism relies on the tension provided by the nozzle retainer, maintaining a secure hold while allowing the operator to easily adjust or replace the nozzle as needed. Whether utilized in automotive manufacturing, heavy equipment fabrication, or general structural steel work, this generic replacement part delivers consistent performance and durability comparable to OEM standards at a more accessible price point.
By integrating this nozzle into your welding supply inventory, you ensure that your welding operations maintain high uptime. The consistent internal geometry ensures laminar gas flow, reducing turbulence and minimizing the risk of porosity in the weld pool. It is an essential component for maintaining the integrity of the gas shield in standard duty MIG welding processes.
