0469754880 - ESAB PSF 400 Slip-On Gas Nozzle

Genuine ESAB PSF 400 Slip-On Nozzle for Industrial MIG Welding

The ESAB PSF 400 Nozzle (Part Number 0469754880) is a premium replacement consumable designed specifically for the widely used PSF 400 series of MIG welding guns. In industrial fabrication environments, the integrity of your welding torch consumables is paramount to maintaining productivity and weld quality. This nozzle features a convenient slip-on design, which eliminates the need for threaded connections that can seize up due to thermal expansion or spatter accumulation. The friction-fit mechanism ensures the nozzle stays securely in place during operation while allowing for quick removal when it is time to clean the nozzle or replace the contact tip.

Constructed from high-grade copper alloy, this nozzle is engineered to withstand the intense radiant heat generated during high-amperage welding. The material offers excellent thermal conductivity, helping to dissipate heat away from the front end of the torch, thereby extending the life of the nozzle and the internal consumables. The geometry of the nozzle bore is precision-machined to promote laminar gas flow. This is critical for preventing atmospheric contamination of the weld pool, which can lead to porosity and weak welds. By ensuring a smooth, turbulence-free shield of gas, the ESAB PSF 400 nozzle helps welders achieve consistent, high-quality results on mild steel, stainless steel, and aluminum applications.

Regular maintenance of your MIG gun involves frequent inspection of the gas nozzle. Over time, spatter can build up inside the nozzle, disrupting gas flow and potentially causing short circuits if it bridges the gap to the contact tip. The smooth internal surface of this ESAB nozzle makes it easier to clean out spatter using standard nozzle reamers or pliers. Using genuine ESAB parts like the 0469754880 ensures that your equipment operates within its original factory specifications, providing the reliability and performance that professional fabricators demand. Whether you are working in heavy manufacturing, automotive repair, or structural steel, this nozzle is an essential component for your PSF 400 welding torch setup.

At Josef Gas, we understand the importance of having the right parts on hand to keep your production line moving. This slip-on nozzle is a direct replacement for the original equipment, ensuring zero compatibility issues. Invest in genuine ESAB consumables to maximize the lifespan of your torch and the quality of your finished welds.
