The ESAB 2228184 is a specific gas nozzle from the PM-359 series, designed for use with compatible ESAB and legacy L-Tec MIG welding guns. This component plays a critical role in the Gas Metal Arc Welding (GMAW) process by directing the shielding gas flow around the contact tip and weld pool. The "50" designation in the product name refers to its bore diameter, which is 0.50 inches (1/2 inch). This intermediate bore size is widely utilized in general fabrication as it offers a balance between gas coverage and accessibility to tighter joints.
Manufactured from high-grade copper alloy, the PM-359 nozzle is engineered to withstand the high thermal loads associated with industrial welding arcs. The material provides excellent thermal conductivity, helping to dissipate heat away from the front end of the gun, thereby prolonging the life of the consumable and the insulator. The nozzle's internal geometry is machined to ensure laminar gas flow, minimizing turbulence that could aspirate atmospheric air into the weld zone and cause porosity.
This nozzle is intended for direct replacement on specific gun models that utilize the PM-359 consumable system. It is essential for maintenance personnel and welding engineers to verify gun compatibility, as the PM-359 series is distinct from other ESAB nozzle lines like the Tweco or Gun Master series. Proper installation ensures electrical isolation (where applicable) and correct nozzle-to-tip stickout relationships, which are vital for maintaining stable arc characteristics and consistent weld penetration.
