0258005581 - ESAB A9 Inlet Nozzle 0.8mm (Pack of 5)

Precision Wire Feeding for A9 Systems

The ESAB 0258005581 Inlet Nozzle is a critical replacement component engineered specifically for the A9 Push-Pull MIG gun system. Designed to accommodate 0.8mm (0.030-inch) welding wire, this nozzle serves as the primary interface between the wire feeder mechanism and the gun liner. In push-pull systems, where synchronization between the cabinet feeder and the gun motor is paramount, the inlet nozzle plays a vital role in minimizing friction and ensuring the wire enters the liner concentrically.

Manufactured to strict OEM tolerances, this nozzle prevents the wire from scraping against the housing, which can generate metal shavings (swarf) that eventually clog the liner or contact tip. This is particularly important when welding with softer wires such as aluminum, which are prone to deformation and shaving. By maintaining a precise 0.8mm bore, the nozzle ensures that the wire path remains stable, contributing to consistent arc characteristics and reducing the load on the drive motors.

This package contains five (5) replacement inlet nozzles, allowing maintenance teams to keep critical spares on hand. Regular inspection and replacement of the inlet nozzle are recommended as part of a preventative maintenance schedule to avoid downtime associated with feed failures. Whether used in automated environments or manual fabrication, genuine ESAB parts ensure the longevity and reliability of your welding equipment.
