401-49-50 - Tregaskiss 401-49-50 MIG Gun Nozzle, 1/2 Inch Bore, Flush Tip

Genuine Tregaskiss 401-49-50 MIG Nozzle

The Tregaskiss 401-49-50 is a premium OEM nozzle designed to meet the rigorous demands of industrial MIG welding. As part of the renowned Tregaskiss Common Consumable Platform, this nozzle is engineered for compatibility with a wide range of Tregaskiss TOUGH GUN™ Robotic and Semi-Automatic MIG guns. It features a 1/2-inch (12.7 mm) bore orifice, which is a standard size suitable for a vast array of welding applications, balancing gas flow velocity with coverage area to ensure porosity-free welds.

One of the defining characteristics of the 401-49-50 is its flush contact tip relationship. In this configuration, the end of the contact tip sits flush with the end of the nozzle. This design is particularly advantageous for welders who require better visibility of the arc and the weld puddle, as the nozzle does not obscure the work area as much as a recessed tip might. Furthermore, a flush nozzle reduces the likelihood of bridging the contact tip to the workpiece in tight spaces while still providing adequate gas shielding. It is an excellent choice for short-circuit MIG welding and general fabrication tasks where maneuverability is key.

Constructed from high-grade copper alloy, the nozzle is built to withstand intense thermal cycling. The material properties ensure rapid heat dissipation, keeping the front-end consumables cooler and extending their service life. The heavy-duty wall thickness helps resist deformation from accidental impacts and makes the removal of weld spatter easier during maintenance cycles. Inside, the nozzle features high-temperature insulation material that effectively isolates the electrically live components from the outer shell, preventing accidental arcing against the workpiece or fixtures.

Using genuine Tregaskiss OEM consumables like the 401-49-50 is critical for maintaining the performance standards of your welding equipment. Aftermarket copies often suffer from inferior dimensional tolerances and lower-grade materials, leading to inconsistent gas flow, overheating, and premature failure. By choosing the 401-49-50, you ensure a secure fit on the retaining head, a leak-free gas seal, and the reliability required for high-volume production environments.
