Pro-source 23T-37 Mig Welder Gas Nozzle

Product Description

The PRO-SOURCE 23T-37 is a self-insulated gas nozzle designed for MIG welding applications. It mounts at the end of a MIG gun and directs shielding gas flow around the weld puddle to protect it from atmospheric contamination. The nozzle accommodates a maximum wire outside diameter of 3/8 inch and a minimum wire outside diameter of 0.023 inch, making it compatible with a range of common MIG wire sizes. This part is typically installed by welding technicians and maintenance professionals performing MIG torch servicing or scheduled consumable replacement.

This nozzle is suited for light-duty to mid-range MIG welding setups where a self-insulated nozzle design is required. The self-insulated construction reduces the risk of shorts between the nozzle and the contact tip, which is a common failure point in high-arc-frequency environments. It is a direct consumable replacement item and is sold individually, with a minimum order of two units per transaction.

Key Features

• Self-insulated nozzle construction reduces contact tip shorting
• Maximum wire outside diameter: 3/8 inch
• Minimum wire outside diameter: 0.023 inch
• Compact profile at 3.2 inches length and 0.92 inches width
• Lightweight at approximately 0.208 pounds per unit

Compatibility

Designed as an OEM-style replacement gas nozzle for MIG welding guns that accept self-insulated nozzle consumables in this size class.

Installation Notes

Installation is performed by welding technicians as part of routine MIG gun consumable maintenance. Before replacing the nozzle, power down the welder and allow the torch to cool completely. Thread or press the nozzle onto the gun neck per the torch manufacturer's procedure, ensuring a secure seat to maintain consistent gas coverage. Inspect the contact tip and liner at the same time, as these are typically serviced together.
