Pro-source 169-724 Mig Welder Gas Nozzle Self Insulated

Product Description

The PRO-SOURCE 169-724 is a self-insulated MIG welder gas nozzle designed to direct shielding gas flow around the weld pool during MIG welding operations. It accepts wire outside diameters from 0.023 inches minimum up to 0.5 inches maximum, covering a broad range of common MIG wire sizes used in production and repair welding. The nozzle measures 2.25 inches in length with a 0.94-inch width and height profile, making it a compact, direct-fit consumable. It weighs 0.14 pounds. Welding technicians and fabricators install this nozzle as a routine consumable replacement to maintain consistent gas coverage and arc stability at the weld joint.

This gas nozzle is suited for MIG welding applications in light industrial, maintenance, and fabrication environments. The self-insulated design reduces the risk of arc-over between the nozzle body and the contact tip, which is important in tight joint configurations or when the nozzle makes incidental contact with the workpiece. It is sold individually and is intended as a replacement consumable for MIG welding guns that accept this nozzle profile. Welders performing regular torch maintenance will find this nozzle appropriate for scheduled consumable changeovers.

Key Features

• Self-insulated nozzle body reduces arc-over risk between nozzle and contact tip
• Accepts wire outside diameters from 0.023 inches minimum to 0.5 inches maximum
• Compact form factor: 2.25 inches long by 0.94 inches wide and tall
• Lightweight at 0.14 pounds for easy handling during consumable replacement
• Sold as a single unit for targeted consumable replenishment

Compatibility

Designed as an OEM-style replacement MIG welder gas nozzle for welding guns that accept a self-insulated nozzle with a 0.94-inch diameter profile and 2.25-inch length. Verify nozzle thread pattern and gun body fitment before installation.

Installation Notes

Gas nozzle replacement on MIG welding guns is performed by welding technicians as part of routine torch maintenance. Always disconnect the welding gun from the wire feeder and power source before removing or installing nozzles. Use appropriate nozzle removal tools or pliers with jaw protection to avoid damaging the nozzle seating surface or contact tip. Inspect the contact tip and diffuser for spatter buildup or wear when replacing the nozzle.
