10501092 - Tweco Classic No. 5 MIG Gun - 500A, 15ft, Miller Connection

Heavy-Duty Industrial Performance

The Tweco Classic No. 5 MIG Gun is a staple in the heavy fabrication industry, renowned for its rugged durability and high-amperage capability. Designed to handle up to 500 Amps at a 60% duty cycle (using CO2), this air-cooled gun is engineered for the most demanding welding environments, including structural steel, shipbuilding, and heavy equipment manufacturing. Its robust construction ensures it can withstand the heat and physical abuse typical of industrial jobsites.

Seamless Compatibility

This specific model (SKU: 10501092) comes pre-configured with a Miller-style rear connection, allowing for immediate plug-and-play use with compatible Miller wire feeders. The 15-foot cable assembly provides ample reach, giving operators the flexibility to move around large workpieces without constantly repositioning the feeder. The cable itself is constructed with high-quality copper stranding and a durable outer jacket to resist cuts, abrasion, and heat.

Easy Maintenance and Consumables

One of the primary advantages of the Tweco Classic series is its serviceability. The gun utilizes standard Tweco consumables—including 15 Series contact tips, 25 Series nozzles, and 45 Series liners—which are widely available and cost-effective. The mechanical connection of the cable to the gun handle and rear plug allows for field repairs, significantly reducing downtime compared to crimped or non-repairable alternatives. For facility managers and procurement specialists, the Classic No. 5 represents a reliable, long-term investment in welding productivity.
