0332322001 - ESAB Intermediate Nozzle for ST/MT Series Guns (.045-5/64)

Technical Overview of the ESAB 0332322001 Intermediate Nozzle

The ESAB 0332322001 is a specialized intermediate nozzle designed to facilitate the transfer of shielding gas and welding current within specific legacy ESAB MIG guns. Engineered for heavy-duty industrial applications, this component serves as the critical interface between the gun's conductor tube and the contact tip. It is specifically calibrated for wire diameters ranging from .045 inches to 5/64 inches, making it suitable for structural steel fabrication and heavy manufacturing where larger diameter solid or flux-cored wires are utilized.

Manufactured to precise OEM tolerances, this nozzle ensures concentric alignment of the contact tip, which is vital for consistent wire feeding and arc targeting. The component is compatible with a range of classic ESAB and L-Tec torch models, including the ST-16, ST-21, ST-23A, as well as the MT-200, MT-300, and MT-400 series. Its design incorporates optimized gas ports that promote laminar flow of the shielding gas, reducing turbulence and minimizing the risk of porosity in the weld pool. The robust brass or copper alloy construction provides excellent thermal conductivity, aiding in the dissipation of heat generated during high-amperage welding cycles.

Proper maintenance of the front-end consumables is essential for the longevity of the welding torch. The intermediate nozzle acts as a heat sink and a gas diffuser; wear or blockage in this component can lead to erratic arcs, poor gas coverage, and overheating of the contact tip. By utilizing the genuine ESAB 0332322001, operators ensure that the electrical and thermal characteristics of the torch remain within factory specifications, thereby maintaining weld quality and equipment reliability.
