64-2550 - 401-5-50 Heavy Duty MIG Nozzle 1/2 Inch Flush Tip for Tregaskiss Guns

Reliable 401-5-50 Tregaskiss Style MIG Nozzle

Maximize the efficiency of your welding operations with the 401-5-50 Tregaskiss Style Heavy Duty Nozzle. Designed as a high-quality aftermarket replacement, this nozzle is engineered to fit 300-amp and 400-amp Tregaskiss MIG guns, widely used in industrial fabrication and manufacturing. Whether you are running a busy production line or a custom fabrication shop, having reliable consumables is key to maintaining arc stability and weld quality.

This specific nozzle features a 1/2-inch (12.7 mm) bore, which is a standard size for many general-purpose welding applications, offering a balanced shield gas flow that protects the weld pool from atmospheric contamination. The flush tip relationship means the contact tip sits flush with the end of the nozzle. This configuration is excellent for short-circuit MIG welding and situations where the welder needs to get closer to the work surface without compromising gas coverage. It also helps prevent bridging and spatter buildup inside the nozzle compared to recessed tips in certain applications.

Constructed from heavy-duty brass, this nozzle is built to endure the thermal stress of high-amperage welding. It is fully compatible with standard front-end consumables, specifically the 404-3 gas diffuser and 402-3 nozzle retainer. By choosing this Tregaskiss-style replacement, you get the performance you expect at a price point that helps manage your consumable costs effectively.
