Victor 12401221 Mig Welder Gas Nozzle No. 2 No. 4 Mig Guns

Product Description

The VICTOR 12401221 is a Nozzle Short Stop gas nozzle designed for MIG welding applications. It mounts at the front end of the MIG gun and directs shielding gas flow around the weld puddle to protect the arc from atmospheric contamination. This nozzle is a direct-fit replacement component for compatible MIG guns and is typically installed or replaced by welding technicians, fabricators, and maintenance professionals during routine gun maintenance or after nozzle wear. The nozzle accommodates a maximum wire outside diameter of 0.625 inches, making it suitable for a range of common wire sizes used in MIG welding work.

This gas nozzle is intended for use with No. 2 and No. 4 MIG guns. It is suited to both light fabrication and general-purpose welding environments where consistent shielding gas coverage is required. Replacing a worn or spattered nozzle restores proper gas flow geometry and helps maintain weld quality. This is a single-unit replacement part, packaged individually, and is appropriate for shops and field technicians who service MIG gun components on a regular basis.

Use appropriate pliers or a nozzle removal tool to avoid damage to the gas diffuser or contact tip during changeout. Follow the gun manufacturer's torque and seating guidelines to ensure a proper gas seal.
