When professional welders think of reliability, they think of the Tweco Classic No. 4. For decades, this MIG gun has been the workhorse of the welding industry, setting the standard for durability and performance. If you are running a Miller machine and need a gun that can handle the heat of heavy fabrication, the Tweco 10401127 is your ultimate solution. With a massive 400-amp rating, this air-cooled beast is built to burn wire all day long without overheating or faltering.
This model comes equipped with a generous 20-foot cable, giving you the freedom to move around large assemblies, trailers, or structural beams without dragging your feeder with you. The rugged handle is designed to fit comfortably in a gloved hand, reducing fatigue during long shifts. The trigger is tested to withstand millions of cycles, ensuring that your arc starts every time you pull it. Plus, the heavy-duty spring strain relief at both the handle and the feeder end protects the cable from kinking and damage, extending the life of your investment.
One of the biggest advantages of the Tweco Classic No. 4 is the consumables. It uses standard Tweco parts that are available at almost every welding supply shop in the world. You won't have to hunt for proprietary tips or nozzles. This specific gun is set up out of the box for 1/16" wire, making it ready for heavy structural welding right away. Whether you are welding thick plate, pipe, or heavy machinery, this gun delivers the consistent arc and wire feeding you need to lay down perfect beads.
