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

Reliable Nozzle for Tregaskiss Style Guns

Keep your production line moving and your welds clean with this standard duty 401-4-50 replacement nozzle. If you are running a 300A or 400A Tregaskiss® style Tough Gun, you know that a fresh, well-designed nozzle is the first line of defense against porosity and weld defects. This nozzle features a 1/2-inch bore, which is the versatile "sweet spot" for most standard wire diameters and transfer modes, giving you a solid, laminar shield of gas around the puddle every time you pull the trigger.

The recessed tip design is a favorite among professional welders for good reason. By sitting the contact tip back slightly inside the nozzle (approximately 1/8 inch), the tip stays cleaner and cooler, significantly reducing the chance of burn-backs or spatter bridging that can stop you in your tracks. This protection means less time scraping out spatter and more time welding.

Installation is a breeze thanks to the slip-on fit. It slides right onto your existing 402-3 nozzle retainer, making changeouts quick and painless—even when wearing gloves. Whether you are fabricating mild steel components or running automated welding cells, this nozzle delivers the fit, finish, and performance you expect from your equipment, helping you lay down consistent beads shift after shift without breaking the bank.
