Parker Heavy Duty MIG Nozzle 5/8 Inch Recessed for Tweco #4

Reliable Replacement: Parker HD 5/8" Recessed Nozzle

Keep your MIG welding operations running smoothly with the Parker P401-6-62 Heavy Duty Nozzle. Designed as a perfect fit for Tweco #4 style MIG guns, this nozzle is a staple for any welder operating in the 300 to 400-amp range. If you are looking for a durable replacement for the standard 401-6-62 part, this Parker unit offers exceptional build quality and precise dimensions to ensure your equipment performs at its best.

The 5/8-inch bore size is the go-to configuration for a wide variety of welding tasks, offering a generous gas envelope that shields the molten puddle effectively, even when welding at higher travel speeds. The "recessed" specification refers to the relationship between the nozzle opening and the contact tip. With the tip recessed, it is shielded from the immediate heat of the arc and physical impact, reducing the frequency of tip changes and minimizing the risk of electrical shorts against the base metal. This makes the P401-6-62 particularly user-friendly for operators who need to drag the nozzle or work in confined spaces.

Durability is key in a heavy-duty nozzle, and the Parker P401-6-62 is built to last. The robust copper construction withstands the intense heat of high-amperage spray transfer or globular transfer welding. Its smooth exterior finish resists spatter adhesion, making it easier to clean during routine maintenance. Simply using a pair of MIG pliers or a nozzle reamer will keep the bore clear and the gas flowing smoothly. This nozzle is part of the standard 3-piece front-end system (nozzle, insulator, gas diffuser), allowing for quick and easy changeovers on the shop floor.
