The Tweco Classic No.4 MIG Gun (1040-1613) represents the pinnacle of durability and performance in the air-cooled welding gun market. Known simply as the "Number 4" by welders across the globe, this tool has defined the standard for heavy-duty industrial welding for decades. This specific configuration features a 15-foot (4.6 meter) cable and a Euro-Kwik back-end connection, making it instantly compatible with a vast array of European power sources and modern multi-process machines that utilize the Euro standard.
Rated at 400 Amps at 60% duty cycle (using CO2), the Classic No.4 is built to handle high-heat applications without faltering. It is pre-configured for 1/16-inch (1.6mm) wire, making it an excellent choice for structural steel fabrication, heavy equipment manufacturing, and flux-cored arc welding (FCAW) where larger diameter wires are required. The gun utilizes the widely available Tweco 14 Series contact tips, 24 Series nozzles, and 54 Series gas diffusers, ensuring that replacement parts are never hard to find.
The construction of the Classic No.4 focuses on longevity and operator comfort. It features a heavy-duty paddle switch that is easy to operate even with thick welding gloves, and the handle design is ergonomically shaped to reduce fatigue during long shifts. The cable assembly is reinforced to resist cuts, burns, and abrasion common in harsh shop environments. Whether you are welding thick plate in a shipyard or fabricating structural beams, the Tweco Classic No.4 delivers the consistent arc stability and wire feeding performance professionals demand.
