Q401-6-62 - Tregaskiss 401-6-62 TOUGH LOCK Heavy Duty Nozzle, 5/8 in. Bore

Industrial Grade Heavy Duty MIG Nozzles

The Tregaskiss 401-6-62 is a premium heavy-duty nozzle designed to meet the rigorous demands of high-volume industrial manufacturing and robotic welding cells. Engineered as part of the renowned TOUGH LOCK™ Consumable System, this nozzle plays a critical role in maintaining arc stability and shielding gas integrity. The nozzle features a 5/8-inch (15.875 mm) bore, which provides an optimal balance between gas coverage and accessibility, making it suitable for a wide range of joint configurations and transfer modes, including spray transfer and pulsed MIG.

Constructed from high-quality brass, the "Heavy Duty" designation indicates a thicker wall cross-section compared to standard duty nozzles. This added mass significantly improves thermal conductivity, allowing the nozzle to absorb and dissipate heat more effectively during high-amperage welding cycles. This thermal management is essential for preventing the nozzle from overheating, which can lead to spatter adhesion, deformation, and premature failure. The 1/8-inch (3.175 mm) contact tip recess is a strategic design choice that helps protect the contact tip from radiant heat and reduces the likelihood of the tip shorting against the workpiece, particularly when welding in tight corners.

For facility managers and procurement specialists, the 401-6-62 offers excellent value through its durability and compatibility. It fits both Tregaskiss TOUGH GUN™ robotic MIG guns and Bernard® Q-Gun™ semi-automatic MIG guns equipped with TOUGH LOCK consumables. This cross-compatibility simplifies inventory management for shops utilizing both manual and automated welding processes. The secure engagement of the TOUGH LOCK system ensures that the nozzle remains concentric and tight, reducing gas turbulence and porosity defects caused by air entrainment.

Supplied in a convenient pack of 5, these nozzles are an essential consumable for maintaining uptime in continuous production environments. Their robust design minimizes the frequency of changeovers, directly contributing to overall equipment effectiveness (OEE) and reducing the total cost of ownership for the welding cell.
