Tweco 23-62 Self-Insulated MIG Nozzle, 5/8" Bore (1230-1076)

Reliable Performance with the Tweco 23-62 Nozzle

When you are in the middle of a long weld, the last thing you want to worry about is your front-end consumables failing. The Tweco 23-62 MIG Nozzle is the workhorse of the welding industry, trusted by fabricators for its durability and ease of use. Designed to fit your trusty Tweco #3 or #4 MIG gun, this nozzle features a 5/8-inch bore, which is the "goldilocks" size for most welding jobs—large enough to provide a wide blanket of shielding gas, but compact enough to get you into corners and tight fit-ups.

The 23-62 uses a self-insulated, slip-on design. This means you don't have to mess around with threads that get seized up with spatter. When it's time to clean out the nozzle or change a tip, you simply twist and pull it off, get your work done, and slide it back on. The friction fit stays tight even as the gun heats up, ensuring your nozzle doesn't wobble or fall off during overhead welding. Made from heavy-duty copper, it pulls heat away from the front end, keeping your consumables cooler and lasting longer.

Whether you are running mild steel, stainless, or aluminum, consistent gas coverage is key to avoiding porosity. The precision machining of the Tweco 23-62 ensures that your shielding gas flows smoothly around the contact tip and over the weld puddle. This reduces turbulence and helps you lay down cleaner, stronger beads. Upgrade your consumable kit with genuine Tweco parts and experience the difference in arc stability and part longevity. This pack contains one nozzle, ready to go right out of the box.
