Pro-source 4295 Mig Welder Gas Nozzle Self Insulated

Product Description

The PRO-SOURCE 4295 is a self-insulated gas nozzle designed for MIG welding guns. It directs shielding gas flow around the weld puddle to protect the arc and molten metal from atmospheric contamination. The nozzle accepts wire outside diameters from 0.030 inches up to 3/8 inches, making it compatible with a range of MIG wire sizes commonly used in fabrication and repair work. At 3.26 inches in length and 0.87 inches in width, it is a compact, direct-fit replacement component. Welders and maintenance technicians replace this part as part of routine torch consumable maintenance to maintain consistent weld quality and shielding gas coverage.

This nozzle is suited for MIG welding applications in light fabrication, general maintenance and repair, and industrial assembly environments. It is a single-piece replacement consumable installed directly onto the MIG gun body. The self-insulated design eliminates the need for a separate insulator sleeve, simplifying the replacement process and reducing part count during torch servicing. It is appropriate for both shop and field use wherever a MIG welding gun requires a gas nozzle consumable replacement.

Installation Notes

Gas nozzle replacement on a MIG welding gun is typically performed by a welder or welding equipment technician. Before replacing the nozzle, disconnect the welding machine from its power source and allow the torch to cool completely. Unthread or pull the worn nozzle from the gun neck, inspect the contact tip and diffuser for wear, and install the replacement nozzle securely before resuming operation. Follow applicable AWS and equipment manufacturer safety guidelines during torch servicing.
