OVERVIEW

Heavy-Duty Industrial MIG Welding Gun

The Tweco Classic No. 4 MIG Gun (SKU: 10401930) is a premier choice for professional fabricators requiring a robust, air-cooled welding torch capable of handling high-amperage applications. Rated at 400 Amps at a 60% duty cycle, this gun is engineered to withstand the rigors of heavy manufacturing, structural steel fabrication, and general industrial maintenance. The "Classic" series is renowned for its durability and ease of maintenance, making it a staple in welding shops worldwide.

This specific configuration features a 15-foot cable assembly, providing ample reach for working around large assemblies without moving the wire feeder constantly. The backend is terminated with a Lincoln-style direct plug, ensuring seamless compatibility with a wide range of Lincoln Electric wire feeders and power sources. It comes pre-setup for .035" to .045" (0.9mm - 1.2mm) wire diameters, covering the most common range for structural welding tasks.

Maintenance is simplified thanks to the use of standard Tweco consumables. The gun utilizes the widely available 14 Series contact tips, 24 Series gas nozzles, and 54 Series gas diffusers. The handle design is ergonomic yet tough, featuring a heavy-duty trigger tested for millions of cycles. The cable assembly includes a durable outer jacket that resists cuts, abrasion, and heat, protecting the copper stranding and liner within. Whether running flux-cored wires or solid wires with shielding gas, the Tweco Classic No. 4 delivers consistent arc performance and reliable wire feeding.
