OVERVIEW

Genuine ESAB 998589 1/4-Inch MIG Nozzle

The ESAB 998589 is a specialized MIG welding nozzle designed to provide focused gas coverage for precision applications. With a 1/4-inch (6.4 mm) bore, this nozzle is significantly narrower than standard 1/2-inch or 5/8-inch nozzles, making it the ideal choice for welding in restricted spaces, tight corners, or for specific spot welding tasks where a smaller profile is required.

Manufactured from high-grade copper alloy, this nozzle offers excellent thermal conductivity and resistance to heat buildup, ensuring a long service life even under demanding industrial conditions. It is engineered specifically for compatibility with ESAB's legacy and current MIG gun lines, including the popular MT-200, MT-250, and MT-400 series, as well as the ST-23A. Using genuine ESAB consumables ensures that your equipment maintains the correct gas flow characteristics and electrical insulation properties intended by the manufacturer.

Whether you are performing automotive bodywork, intricate fabrication, or simply need to reach a weld joint that a standard nozzle obscures, the ESAB 998589 provides the clearance and control necessary for high-quality results. Its smooth finish also helps minimize spatter adherence, making cleaning and maintenance quick and easy.

FAQ

The bore size is 1/4 inch (approximately 6.4 mm).

It is designed for ESAB MT-200, MT-250, MT-400, and ST-23A MIG guns.

It is made from a durable copper alloy for heat resistance and longevity.

Generally, a 1/4-inch nozzle is too small for high-amperage spray transfer as it may overheat or clog with spatter quickly; it is better suited for short-circuit and low-amperage applications.

A smaller bore concentrates the gas coverage and allows access to tighter spaces, but it requires more frequent cleaning to prevent spatter bridges.

This is typically a slip-on style nozzle designed to fit over the standard insulator of the compatible MT-series guns.

While physically possible, flux-cored welding (FCAW-S) usually requires a thread protector rather than a gas nozzle, or a specific gasless nozzle. This nozzle is designed for gas-shielded MIG welding.
