401-4-62 - Tregaskiss 401-4-62 SD Nozzle, 5/8" Bore, 1/8" Recess, Slip-On

Reliable Performance for Professional Welders

When you are in the middle of a long weld, the reliability of your torch consumables makes all the difference. The Tregaskiss 401-4-62 Nozzle is built to withstand the rigors of daily industrial welding while delivering consistent results. Featuring a 5/8-inch bore, this nozzle provides excellent gas coverage, helping you lay down clean, porosity-free welds even in drafty shop environments. The 1/8-inch recess is a favorite among welders because it tucks the contact tip back just enough to protect it from the intense heat and spatter of the arc, reducing the frequency of tip burn-backs without obscuring your view of the puddle.

Durability is where this nozzle truly shines. Unlike cheaper alternatives that deform or melt under high heat, the 401-4-62 is made from hard-drawn copper that holds its shape. But the real game-changer is the internal brass insert. If you have ever struggled with a nozzle that wobbles or falls off the diffuser, you will appreciate the secure fit this insert provides. It locks onto the gun, preventing that annoying "rocking" that can mess up your aim and gas flow. This means you can focus on your travel speed and gun angle, knowing your front-end parts are secure.

Maintenance is also a breeze with this nozzle. The smooth copper finish and rounded edges are designed to shed spatter, so you spend less time scraping out your nozzle and more time welding. When it is finally time to clean the diffuser or swap a tip, the slip-on design lets you pull the nozzle off in seconds—no threads to seize up or cross. The built-in fiberglass insulator adds an extra layer of safety, keeping the nozzle electrically cold so you don't accidentally arc out against your workpiece. Whether you are fabricating structural steel or repairing heavy equipment, the Tregaskiss 401-4-62 gives you the performance and durability you need to get the job done right.
