Pro-source 198855 Mig Welder Gas Nozzle

Product Description

The PRO-SOURCE 198855 is a replacement gas nozzle designed for MIG welding guns. The nozzle directs shielding gas flow around the weld pool, protecting the arc from atmospheric contamination. It measures 2.37 inches in height with a 1.1-inch width and 1.1-inch length, making it a compact, direct-fit replacement. At 0.18 pounds, the nozzle is lightweight and easy to swap during routine gun maintenance. It accommodates wire outside diameters up to 0.0938 decimal inches, covering the most common MIG wire sizes used in production and field welding applications. Welders and fabricators performing scheduled consumable replacements or restoring gun performance after spatter buildup will find this nozzle a straightforward service part.

This gas nozzle is suited for MIG welding guns used in both shop and field environments. It is a consumable replacement part intended for maintenance cycles where nozzle wear, spatter accumulation, or damage to the bore reduces shielding gas coverage and weld quality. Typical applications include light fabrication, structural steel work, and general-purpose MIG welding setups where consistent shielding gas delivery is critical to maintaining clean, sound welds. It is sold individually per package.

Installation Notes

MIG gun nozzle replacement is a standard consumable service task performed by welders and maintenance technicians. Before replacing the nozzle, disconnect the welding gun from the wire feeder and ensure the machine is powered off. Remove the worn nozzle by unscrewing or pulling it free depending on the gun design, clear any spatter from the contact tip area, then seat the new nozzle firmly. Follow the welding gun manufacturer guidelines and applicable AWS or shop safety procedures during service.
