22-37-SS - Tweco Style 22-37-SS MIG Nozzle 3/8" Bore 2-Pack

Reliable Tweco-Style MIG Nozzle for 250A Applications

The 22-37-SS MIG Nozzle is a premium-quality, Tweco-style replacement component designed specifically for light to medium-duty welding applications. Engineered to withstand electrical currents up to 250 amperes, this nozzle is constructed from durable 122 DHP copper alloy tubing. This high-grade material ensures excellent heat dissipation and electrical conductivity, which are critical for maintaining nozzle integrity during prolonged welding sessions. Its 3/8-inch bore is ideal for standard MIG welding tasks, providing optimal shielding gas coverage to the weld pool to prevent porosity and contamination.

This specific model features a "Short Stop" design, which typically provides a 1/8-inch contact tip recess when installed properly. This recess helps protect the contact tip from excessive spatter and radiant heat, effectively prolonging the life of your consumables and reducing the frequency of tip changes. The nozzle is designed to slip seamlessly over the standard #32 nozzle insulator (Stock No. 1320-1100), allowing for easy installation and adjustment to achieve the desired nozzle-to-tip relationship.

It is fully compatible with Tweco No. 2 Classic MIG guns, the Tweco Weldskill series, and select Lincoln Magnum MIG guns. Whether you are fabricating in a professional workshop or performing maintenance repairs, the 22-37-SS offers reliable performance that meets industrial standards. The part number is often roll-stamped on the exterior for easy identification, ensuring you always have the right part for the job. This nozzle works in conjunction with the #52 gas diffuser to maintain a stable arc and consistent shielding gas flow, making it an essential consumable for your MIG welding setup.
