Victor 12401220 Mig Welder Gas Nozzle 0.625 in Bore

Product Description

The VICTOR 12401220 is a replacement gas nozzle designed for MIG welding applications. It features a tapered, three-piece design with a 0.625-inch bore diameter and threads directly onto the gas diffuser for a secure, repeatable fit. Rated for up to 400 amps, this nozzle handles demanding continuous wire-feed welding workloads. The design includes easy-identification markings to speed up nozzle selection and replacement during production or service work. It is installed by welding technicians and fabricators maintaining MIG gun consumables on Series 24 gun assemblies.

This nozzle is intended for use with No. 2 and No. 4 MIG guns in the Series 24 lineup. It is well suited to both shop fabrication and field welding environments where high-amperage wire-feed welding is performed. The tapered nozzle profile supports consistent shielding gas coverage at the weld zone, making it appropriate for structural, sheet metal, and general fabrication work where arc stability and gas coverage are critical to weld quality.

Compatibility

Designed for use with No. 2 and No. 4 MIG guns in the Series 24 platform as stated by the manufacturer.

Installation Notes

This nozzle is installed by welding technicians as part of routine MIG gun consumable maintenance. Before replacing the nozzle, disconnect the welding machine from its power source and allow the gun to cool completely. Thread the nozzle onto the gas diffuser by hand until seated; avoid cross-threading. Inspect the gas diffuser and contact tip for wear at the same time, as consumable condition affects shielding gas flow and arc performance.
