It measures 5/8 inch in diameter and 1.07 inches wide, providing the correct bore geometry for high-amperage semiautomatic MIG welding applications. Built to OEM quality standards, this nozzle delivers consistent shielding gas coverage at the weld puddle. It is installed and replaced by welding technicians and fabricators performing routine consumable maintenance on Tweco-compatible MIG gun assemblies. Each nozzle is marked with its part number or size to simplify identification during changeout.
This nozzle is suited for high-amperage MIG welding operations in fabrication shops, manufacturing facilities, and industrial maintenance environments. It fits Tweco-style MIG guns in the 400A to 600A range, including guns from the Classic, Weldskill, Spray Master, and Supra product lines. Its coarse-thread design allows for quick removal and reinstallation during consumable swaps, minimizing downtime between welds.

MIG nozzles are replaced by welding technicians as part of routine consumable maintenance. Always power down and disconnect the welding machine before removing or installing nozzles to avoid accidental arc initiation. Use the appropriate nozzle wrench or pliers to avoid deforming the nozzle body during installation. Ensure the gas diffuser and contact tip are inspected at the same time as the nozzle to maintain consistent shielding gas flow and weld quality.
