10501175 - Tweco Classic No. 5 MIG Gun, 500A, 15ft, Miller Connection (3/32" Wire Setup)

The Legend of the Shop Floor

If you have been in the welding game for a while, you know the Tweco Classic No. 5. It isn't just a MIG gun; it's a tool that has built bridges, skyscrapers, and ships for decades. This specific model (1050-1175) comes ready to plug directly into your Miller machine, giving you the best of both worlds: the power source you trust and the gun that refuses to quit. With a massive 500 Amp rating, this air-cooled beast is designed to run hot and heavy without melting down in your hand. It is set up right out of the box for 3/32" (2.4mm) wire, making it the ultimate weapon for laying down serious metal with large diameter flux-cored wires.

Built for the Grind

Welding isn't a clean or gentle job, and the Classic No. 5 knows that. The construction is simple, rugged, and effective. The metal-jacketed conductor tube and heavy-duty nozzle are made to take a beating. Whether you are gouging, running high-deposition flux core, or spraying heavy MIG, this gun handles the heat. The 15-foot cable gives you the freedom to move around your workpiece, and the cable housing is tough enough to be dragged over steel plates and concrete without failing. Plus, the air-cooled design means you don't have to fuss with water coolers, hoses, or leaks—just plug it in and burn wire.

Comfort and Control

Despite its size and power, the Classic No. 5 is designed with the welder in mind. The handle shape is the industry standard for a reason—it fits the glove perfectly. The trigger action is positive and reliable, giving you precise control over your arc starts and stops. Maintenance is a breeze too; when you eventually wear out a tip or a liner, swapping them out takes minutes, not hours. You don't need a degree to fix it; you just need your standard tools. When the job demands high amps and zero excuses, grab the Tweco No. 5 and get to work.
