25CT-62 - Tweco 25CT Series Heavy-Duty MIG Nozzle, 5/8 in. Bore, Recessed Tip

Heavy-Duty Tweco 25CT-62 Nozzles for Professional Welders

When your welding projects demand reliability and endurance, the Tweco 25CT-62 MIG Nozzle is the professional's choice for heavy fabrication. Built to handle the heat, these nozzles are rated for applications up to 550 amperes, making them suitable for structural steel, heavy equipment manufacturing, and shipyards. The nozzle is constructed from solid copper alloy, which stands up to the abuse of daily industrial use far better than cheaper, thin-walled alternatives. This durability translates to fewer interruptions for nozzle cleaning and replacement, keeping your arc on time and your productivity high.

The 25CT-62 features a 5/8-inch bore, a standard size for many industrial MIG applications, offering excellent gas coverage for clean, porosity-free welds. The recessed tip design is a favorite among professional welders because it provides a slight standoff for the contact tip. This recess helps protect the tip from the intense heat of the arc and reduces the likelihood of the tip shorting against the workpiece during tight maneuvers. Furthermore, the recessed geometry acts as a small cup to help direct the shielding gas more effectively, which is crucial when welding in drafty shop environments or outdoors.

Tweco has designed this nozzle with the welder's convenience in mind. The two-piece system allows you to thread the nozzle housing onto a separate insulator. This coarse-thread connection is rugged and designed to resist seizing, even after long shifts of hot work. Because the part number is permanently stamped into the metal surface, you never have to guess if you have the right size—even if the nozzle is dirty or worn, the ID remains visible. Sold in a convenient 2-pack, these nozzles ensure you always have a spare on hand. Whether you are running a Spray Master or a classic Tweco gun, the 25CT-62 delivers the consistent performance required to produce high-quality welds shift after shift.
