12201307 - Tweco 22-62 Heavy Duty MIG Nozzle, 5/8" Bore, Recessed Tip (2-Pack)

Tweco 22-62 Heavy Duty MIG Nozzle (2-Pack)

The Tweco 22-62 MIG Nozzle is a premium consumable designed for heavy-duty welding applications requiring reliability and precision. Engineered for use with Tweco No. 2 MIG guns and compatible 22 Series setups, this nozzle is rated for operations up to 250 Amperes. The 2-pack configuration ensures that professional fabricators always have a spare on hand to maintain productivity. This specific model features a 5/8-inch (16mm) bore, which provides a broad and stable umbrella of shielding gas, essential for maintaining weld pool purity and preventing porosity in critical joints.

Advanced 3-Piece Construction

Tweco utilizes a robust 3-piece design to maximize performance and longevity. The outer housing is cut and formed from 122 DHP (Deoxidized High Phosphorus) copper alloy tubing. This specific alloy is chosen for its excellent thermal conductivity, allowing the nozzle to shed heat rapidly and resist deformation even during prolonged welding cycles. Inside, a solid brass insert is crimped securely in place, providing a durable mounting point that slides smoothly over the gas diffuser's metal spring. This slip-on design facilitates quick changes without the need for threads that can seize due to spatter.

Electrical Insulation and Tip Protection

Safety and component longevity are central to the 22-62 design. The nozzle includes a high-temperature G7 silicone insulator that effectively isolates the electrically live gas diffuser from the outer nozzle housing. This insulation is critical for preventing arc-outs if the nozzle accidentally touches the workpiece. Furthermore, the nozzle is designed with a tip recess of 1/8" to 5/32". This recess places the contact tip slightly back inside the nozzle, offering physical protection against molten spatter and reducing the likelihood of the tip shorting to the base metal, particularly when welding in tight corners or overhead positions.
