Upgrade your welding setup with the Tweco Classic No. 4 MIG Gun, the definition of industrial reliability. This model (SKU: 10401914) is an air-cooled, 400-amp welding torch designed for professional welders who demand performance and longevity. With a 10-foot cable assembly, it offers excellent control and wire feeding characteristics for close-range work, minimizing liner friction and ensuring smooth wire delivery.
The gun features a Miller back-end connection, making it an immediate replacement or upgrade for your existing Miller MIG guns. It is pre-configured for .035" to .045" (0.9mm - 1.2mm) welding wires, suitable for a vast range of GMAW (MIG) and FCAW (Flux-Cored) applications. The Classic No. 4 utilizes Tweco's heavy-duty copper alloy consumables, which provide superior electrical conductivity and heat dissipation compared to standard parts.
Maintenance is straightforward thanks to the modular design. The conductor tube, trigger, and cable connections are easily accessible for service. The metal-jacketed conductor tube is durable and resistant to impact, while the rugged cable outer jacket resists cuts, burns, and abrasion. If you need a MIG gun that works as hard as you do, the Tweco Classic No. 4 is the proven choice.
