63-2150 - 401-4-50 Replacement Nozzle for Tregaskiss Tough Gun, 1/2" Bore, Recessed

Premium Aftermarket Replacement for Tregaskiss 401-4-50

The GEN401-4-50 is a high-performance aftermarket MIG gun nozzle engineered to be fully compatible with Tregaskiss® Tough Gun™ robotic and semi-automatic MIG welding platforms. Designed as a direct replacement for the OEM part number 401-4-50, this nozzle features a precision-machined 1/2-inch (12.7mm) bore orifice. This bore size is the industry standard for a wide range of welding applications, providing a balanced flow of shielding gas to protect the weld pool from atmospheric contamination without excessive turbulence.

Constructed for standard duty cycles, this nozzle is rated for use with 300-amp and 400-amp MIG gun assemblies. It features a recessed contact tip configuration, typically providing a 1/8-inch recess when installed with standard consumables. This geometry is critical for protecting the contact tip from molten spatter, radiant heat, and accidental short circuits against the workpiece, thereby extending the service life of your front-end consumables. The nozzle utilizes a slip-on connection mechanism, designed to fit securely over a 402-3 nozzle retainer and a 404-3 gas diffuser.

Manufactured from high-grade copper alloy, the GEN401-4-50 ensures efficient heat dissipation and excellent electrical insulation from the nozzle body to the contact tip. This component is essential for maintaining the performance and reliability of your Tregaskiss style MIG torch setup, offering a cost-effective solution for high-volume fabrication environments where consumable costs are a key consideration.
