Heavy-Duty Industrial MIG Welding Gun

The Tweco Classic No. 5 MIG Gun (SKU: 1050-1086) is a premier choice for professional welders requiring a high-amperage, air-cooled solution for heavy industrial applications. Rated at 500 Amps at 60% duty cycle using CO2 gas, this gun is engineered to withstand the rigors of structural steel fabrication, shipbuilding, and heavy equipment manufacturing. The unit features a 15-foot cable assembly, providing ample reach for working around large workpieces without moving the wire feeder constantly.

This model utilizes the renowned Tweco-style rear connection, ensuring compatibility with a vast array of wire feeders and power sources equipped with Tweco adapters. The gun is designed with the "Classic" handle, a shape that has been favored by welders for decades due to its balance and durability. Internally, the cable uses heavy-duty copper stranding to minimize resistance and heat buildup, ensuring consistent arc performance even during extended welding sessions.

Maintenance is straightforward with the Classic No. 5. It utilizes standard Tweco consumables, including 15H series heavy-duty contact tips and 25CT series nozzles, which are widely available and cost-effective. The mechanical connection of the cable to the gun and connector block allows for field repairs, significantly extending the service life of the tool compared to crimped or molded alternatives. Whether running solid wire or flux-cored wire, the Tweco Classic No. 5 delivers reliable performance in the toughest environments.
