Industrial Grade 500A MIG Welding Gun

The Tweco Classic No. 5 MIG Gun (1050-1084) is a heavy-duty, air-cooled welding torch designed for high-amperage industrial applications. Rated at 500 Amps at 60% duty cycle using CO2 gas (400 Amps with mixed gas), this gun is engineered to handle flux-cored and solid wire welding in the most demanding environments. The unit features a 12-foot cable assembly, providing ample reach for large fabrication projects while maintaining excellent wire feedability.

This model utilizes the renowned Tweco rear connection, making it directly compatible with a wide range of wire feeders that accept Tweco-style plugs. The gun comes equipped with the signature Classic oval handle, which has been a favorite among professional welders for decades due to its ergonomic grip and maneuverability. The mechanical connection between the cable and the gun is fully field-repairable, reducing downtime and maintenance costs compared to crimped designs.

The Classic No. 5 is built for durability, featuring a heavy-duty metal jacketed conductor tube and robust spring strain reliefs at both the feeder and gun ends. It utilizes standard Tweco 14 Series contact tips, 24 Series nozzles, and 54 Series gas diffusers, ensuring that replacement parts are easy to source and affordable. Whether you are welding structural steel, heavy equipment, or performing general fabrication, the Tweco Classic No. 5 delivers consistent arc performance and reliability.
