12401422 - Tweco 24CT-62F Flush MIG Nozzle 5/8 Bore (2-Pack)

High-Performance Tweco 24CT-62F Nozzles

Optimize your MIG welding setup with the Tweco 24CT-62F Standard Nozzle, supplied in a convenient pack of two. Designed for the demanding professional, this nozzle fits Tweco Spray Master (250, 350, 450) and Tweco Professional (No. 2, 3, 4) series MIG guns. The 24CT-62F is characterized by its 5/8-inch (15.9 mm) bore orifice, which provides optimal gas coverage for short-circuit, globular, and spray transfer modes. This bore size is large enough to ensure a laminar gas flow that effectively shields the molten puddle, yet compact enough to maneuver into standard joints.

The "Flush" designation indicates the contact tip's position relative to the nozzle exit. A flush nozzle is often preferred for applications where visibility is critical, as it allows the welder to see the arc and the wire stick-out clearly. It also helps in maintaining a consistent contact-tip-to-work distance (CTWD). Unlike recessed nozzles, which can sometimes accumulate spatter inside the cup that bridges to the tip, the flush design is easier to inspect and clean. The nozzle utilizes a 3-piece design system involving the nozzle, a nozzle insulator (often built-in or separate depending on the gun generation), and the gas diffuser.

A standout feature of the 24CT series is the coarse thread attachment. In high-heat applications, fine threads can easily become clogged with micro-spatter or seize due to thermal expansion. Tweco's coarse thread geometry mitigates this risk, ensuring that the nozzle can always be unscrewed easily, even after a long shift of high-amperage welding. This nozzle is typically used with the 54A gas diffuser and standard 14-series contact tips. By choosing genuine Tweco consumables, you ensure precise fitment and consistent electrical insulation, reducing the risk of arc wandering or gas turbulence.
