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

Heavy-Duty Industrial Performance with the Tweco Classic No. 5

The Tweco Classic No. 5 MIG Gun (Part Number 1050-1115) is a legend in the welding industry, renowned for its durability, simplicity, and high-performance capabilities in heavy industrial environments. Designed for welders who demand reliability, this air-cooled gun is rated at 500 Amps at a 60% duty cycle using CO2 gas, making it the go-to choice for structural steel, heavy equipment manufacturing, and general fabrication where high heat and long arc times are the norm.

One of the standout features of this model is its 25-foot cable assembly. This extended length provides welders with the freedom to move around large workpieces, such as truck bodies, trailers, or structural beams, without constantly repositioning the wire feeder. Despite its length, the cable is engineered to feed wire smoothly and consistently, minimizing bird-nesting and downtime. The cable itself is protected by a rugged outer jacket that resists abrasion, cuts, and burns, ensuring a long service life even in the harshest shop conditions.

The Classic No. 5 utilizes the famous Tweco connection style, ensuring compatibility with a vast range of wire feeders and power sources that accept Tweco-style backends. Maintenance is straightforward, as the gun uses standard Tweco consumables—including 15 Series contact tips, 25 Series nozzles, and 55 Series diffusers—which are widely available and easy to replace. The gun's handle features the classic oval shape that welders have favored for decades, providing a comfortable, ergonomic grip that reduces hand fatigue during long shifts. Whether you are running solid wire for MIG welding or heavy flux-cored wires, the Tweco Classic No. 5 delivers the consistent arc stability and rugged performance required for professional results.
