OVERVIEW

The Legend, Upgraded for the Modern Pro

You know the handle. You know the feel. The Tweco Classic No. 3 has been the go-to MIG gun for professional welders for generations. But the 10301016 model isn't just a reissue of the past; it is a high-performance evolution. Equipped with Velocity™ Medium Duty consumables, this gun solves the most common frustrations of traditional MIG guns: burn-back, unstable arcs, and overheating tips. The Velocity system uses a threadless, drop-in contact tip that seats firmly into the gas diffuser, creating a solid electrical path that keeps the tip cooler and the arc smoother.

Rated at 350 Amps at 60% duty cycle with CO2 (300 Amps with mixed gas), this air-cooled gun is built for serious work. The 15-foot cable features a heavy-duty jacket and robust strain relief, preventing the liner from kinking and ensuring smooth wire feeding even at acute angles. The Miller® backend connection means you can swap this gun onto your Millermatic or other Miller wire feeders in seconds. No adapters, no hassle—just plug in and weld.

The ergonomics of the Classic No. 3 handle are unmatched. The paddle trigger is responsive yet durable, designed to reduce hand fatigue during long shifts. The conductor tube is rotatable, allowing you to adjust the angle for difficult-to-reach joints. If you are pushing 1/16" flux-cored wire or running standard .035" solid wire, the liner and feed path are optimized for consistency. Stop fighting with cross-threaded tips and erratic arcs. Upgrade to the Tweco Classic No. 3 with Velocity and experience the difference that superior conductivity makes.

Technical Advantages

  • Velocity Technology: Gas ports are integrated into the conductor tube, not the diffuser, improving gas flow and cooling.
  • Solid Electrical Connection: The large surface area of the Velocity tip base ensures maximum current transfer.
  • Rugged Construction: Impact-resistant handle and armored cable connection points.

FAQ

This gun is rated at 350 Amps when using CO2 gas and 300 Amps when using mixed shielding gases, both at a 60% duty cycle.

Yes, this specific model (10301016) comes with a Miller® style rear connection, making it directly compatible with most Miller wire feeders.

This gun uses Tweco Velocity™ series consumables, which feature threadless contact tips and an integrated nozzle system for better performance.

The cable assembly is 15 feet (approximately 4.6 meters) long, providing good reach for most workshop environments.

Yes, the Tweco Classic No. 3 is capable of running both solid MIG wire and flux-cored wires, provided the correct liner and drive rolls are used.

The gun is typically rated for wire sizes up to 1/16 inch (1.6mm), though it is commonly set up for .035 or .045 inch wires.

Velocity consumables offer better arc stability, run cooler due to a solid copper path, and are easier to change because they are threadless.

Yes, the conductor tube (neck) on the Classic No. 3 can be rotated to suit different welding positions and operator preferences.
