10501115 - Tweco Classic No. 5 MIG Gun, 500A, 25ft, Tweco Connection

The Industry Standard: Tweco Classic No. 5 MIG Gun (500A, 25ft)

When it comes to high-amperage air-cooled MIG welding, the Tweco Classic No. 5 (SKU: 1050-1115) stands alone as the industry standard. Built to withstand the rigors of heavy fabrication, this gun is rated for 500 Amps, allowing it to tackle the thickest materials and the most demanding welding procedures without the complexity or maintenance requirements of a water-cooled system. This specific configuration comes equipped with a 25-foot cable, offering maximum reach and flexibility for shop floor operations.

The core of the Classic No. 5's reliability lies in its robust construction. It features a heavy-duty copper conductor strand arrangement within the cable to carry high current with minimal resistance, ensuring that the arc remains hot and stable at the workpiece. The connection end is a standard Tweco style, which is the most common connection in the North American market, making this gun a plug-and-play solution for many Lincoln, Miller, and ESAB feeders equipped with Tweco adapters. The gun is designed to be fully field-repairable; from the trigger switch to the conductor tube, every component can be serviced or replaced, extending the total lifespan of the tool and maximizing your return on investment.

Operators appreciate the Classic No. 5 for its balance and heat management. The air-cooled design is efficient, and the handle is insulated to protect the welder's hand from the intense heat generated during high-amperage welding. It supports a wide range of wire diameters, typically set up for 1/16" (1.6mm) or 5/64" (2.0mm) wires in heavy applications, but adaptable to others with the correct liner and tip changes. With its metal-jacketed conductor tube and heavy-duty spring strain reliefs, the Tweco Classic No. 5 is built to survive drops, drags, and the daily abuse of industrial welding, delivering proven performance weld after weld.
