10301105 - Tweco Classic 3 MIG Gun 300A 25ft Tweco Connection .035-.045

Legendary Performance: Tweco Classic No. 3 MIG Gun (300A, 25ft)

For professional welders who demand durability and proven performance, the Tweco Classic No. 3 MIG Gun stands alone. With a part number of 1030-1105, this 300-amp, air-cooled torch is a staple in shipyards, trailer manufacturing plants, and structural steel shops across the globe. This model is equipped with a 25-foot cable and a standard Tweco back-end connection, offering the freedom to weld large workpieces without constantly repositioning your equipment.

The Classic No. 3 is defined by its robust construction and ease of service. The entire gun is fully repairable—from the trigger switch to the cable assembly—meaning a damaged component doesn't require replacing the entire gun. It comes factory-ready for 0.035" to 0.045" (0.9mm - 1.2mm) wire diameters, covering the most common range for industrial MIG and Flux-Cored welding. The metal-jacketed conductor tube and heavy-duty gas diffuser ensure excellent electrical conductivity and heat dissipation, keeping the front end cooler for longer consumable life.

Welders appreciate the tactile feedback of the heavy-duty trigger and the balance of the curved handle, which aids in precise torch manipulation in out-of-position welds. The coaxial cable design optimizes shielding gas flow and wire feeding, reducing drag and ensuring a stable arc. If you are looking for a MIG gun that has stood the test of time and continues to set the bar for air-cooled performance, the Tweco Classic No. 3 is the definitive choice.
