The Tweco Classic #5 MIG Gun (M515-116) is a powerhouse in the welding industry, renowned for its rugged durability and high-performance capabilities in heavy industrial environments. Designed to handle up to 500 Amps at a 60% duty cycle using CO2 gas, this air-cooled gun is the preferred choice for fabricators who demand reliability without the complexity of water-cooled systems. This specific model comes pre-configured with a Miller back end, ensuring immediate plug-and-play compatibility with most Miller wire feeders and power sources.
At the core of this gun is the legendary Tweco Classic handle. Shaped for ergonomic comfort and operator control, it reduces fatigue during long welding shifts. The 15-foot cable assembly offers significant reach, allowing welders to move freely around large workpieces such as structural steel beams, heavy machinery, and shipbuilding components. The cable itself is constructed with a durable coaxial design that resists cuts, burns, and abrasion, ensuring a long service life even on the toughest job sites.
Maintenance is straightforward with the Tweco Classic #5. It utilizes the widely available 15 Series contact tips, 24 Series nozzles, and 54 Series gas diffusers. The simplified front-end consumable system means you spend less time troubleshooting and more time welding. The gun is set up to run wire diameters from .045" to 1/16", making it ideal for flux-cored and solid wire applications that require high deposition rates. Whether you are welding thick plate or performing multi-pass structural welds, the Tweco Classic #5 delivers consistent arc stability and wire feeding performance.
Choosing the Tweco Classic #5 means investing in a tool that has stood the test of time. Its field-repairable design allows for individual component replacement—from the trigger switch to the gooseneck—extending the overall life of the unit and providing excellent return on investment. Equip your Miller welder with the industry standard for high-amperage air-cooled MIG welding.
