The Legend Returns: Tweco Classic No. 3 for Miller Welders

If you have been welding for any length of time, you know the handle. The Tweco Classic No. 3 is arguably the most recognizable and trusted MIG gun in the history of welding. Known for its rugged reliability and comfortable oval handle, this gun is the daily driver for professional fabricators across the globe. This version (1030-1133) is custom-built with a Miller back end, allowing you to upgrade your Miller machine with the durability and feel of a genuine Tweco torch.

Built for the Real World
Welding isn't a gentle process. You drop things, you drag cables over sharp steel, and you work in hot environments. The Tweco Classic No. 3 is built to take it. The 12-foot cable gives you plenty of room to move around your workpiece without getting tangled, while the heavy-duty strain relief protects the cable connections from stress. The air-cooled design is efficient and simple, removing the need for water coolers and extra hoses, yet it stays cool enough for long runs at 300 amps.

Superior Ergonomics and Control
The famous paddle-style trigger and oval handle profile are designed to fit naturally in your hand, reducing fatigue during long shifts. The trigger action is crisp and reliable, giving you precise control over your arc starts and stops. Because it uses standard Tweco consumables (14 series tips and 24 series nozzles), finding replacement parts is never a headache—you can find them in almost any weld shop or supply store.

Ready to Weld
This gun comes set up for .035" to .045" wire, which covers the vast majority of MIG applications, from thin sheet metal to heavy plate. Whether you are welding mild steel, stainless, or flux-cored applications, the Tweco Classic No. 3 delivers a smooth wire feed and a stable arc. Stop fighting with flimsy stock guns and step up to the industry standard that welders have trusted for decades.
