OVERVIEW

The Legend Returns: Tweco Classic No. 3 MIG Gun

Experience the performance of the welding gun that set the standard for the entire industry. The Tweco Classic No. 3 MIG Gun is a favorite among professional welders for its rugged reliability, ease of use, and "field-repairable" design. Whether you are welding in a fabrication shop, on a pipeline, or in a garage, the Classic No. 3 delivers consistent arc performance and comfortable handling. This model (1030-1113) features a generous 15-foot cable, giving you the freedom to move around your workpiece without restriction.

What sets this specific unit apart is its configuration for 1/16-inch wire. If you are running heavy flux-cored wire or large diameter solid wire, this gun is ready to go immediately—no need to swap out the liner or tips upon arrival. It features the signature Tweco paddle switch, which is easy to operate even with heavy welding gloves, reducing hand fatigue during long welds. The handle is ergonomically shaped and built from high-impact materials to survive drops and rough handling.

Compatibility is key with the Tweco Classic series. It uses standard Tweco consumables that are available at virtually every welding supply store in the world. The Tweco-style rear connection ensures it fits a vast array of wire feeders (adapter plugs may be required for specific Miller or Lincoln machines if they don't have a Tweco block). Invest in a MIG gun that works as hard as you do. The Tweco Classic No. 3 offers the durability to last and the performance to produce high-quality welds shift after shift.

  • High Amperage: 300 Amps of power for heavy plate welding.
