12301220 - Tweco 23H62 Heavy Duty MIG Nozzle 5/8 Inch Bore (2-Pack)

Reliable Gas Coverage for Heavy-Duty Fabrication

The Tweco 23H62 Standard Nozzle is a staple consumable for professional welders requiring consistent performance in high-amperage MIG applications. Designed to fit Tweco #3, #4, and #5 air-cooled MIG guns, this nozzle features a 5/8-inch (15.9 mm) bore, which is the industry standard for general fabrication and structural welding. The "H" in the part number designates its heavy-duty classification, meaning it is built with thicker copper walls to withstand the intense heat generated during prolonged welding sessions at amperages ranging from 300A to 500A.

One of the primary benefits of the 23H62 is its slip-on design. Unlike threaded nozzles that can seize up with spatter, the slip-on interface allows for quick removal and replacement, facilitating easy cleaning of the gas diffuser and contact tip. This package contains two nozzles, ensuring that operators have an immediate replacement available on the shop floor, minimizing downtime. The high-quality copper alloy construction not only dissipates heat effectively but also resists spatter adhesion, making it easier to keep the nozzle clean and the gas flow laminar.

At Josef Gas, we understand that consumable longevity directly impacts production costs. The Tweco 23H62 is engineered with a built-in insulator that protects the gun's front-end parts from electrical shorts if the nozzle accidentally contacts the workpiece. Whether you are welding mild steel, stainless, or aluminum, this nozzle provides the shielding gas coverage necessary to prevent porosity and ensure sound weld quality.

Key Features for Industrial Use

• Standard Bore: 5/8" opening balances gas velocity and coverage area.
• Heavy-Duty Build: Thicker walls for better heat resistance and durability.
• Easy Maintenance: Slip-on fitment simplifies tip changes and spatter removal.
