The Tweco Classic No. 4 MIG Gun (SKU: 10401925) represents the pinnacle of proven performance in the welding industry. For decades, the Classic series has been the go-to choice for professional fabricators requiring reliability, durability, and ease of maintenance. This specific model is configured with a Miller-style rear connection, making it an immediate drop-in replacement or upgrade for compatible Miller wire feeders and welding machines. With a robust 400 Amp rating at 60% duty cycle, this air-cooled gun is engineered to handle high-volume welding tasks involving mild steel, stainless steel, and aluminum applications.
The 15-foot cable assembly offers significant reach, allowing operators to move freely around large workpieces such as structural beams, heavy machinery, and transport trailers without constantly repositioning the power source. The cable itself is constructed with high-quality copper stranding and a durable outer jacket designed to resist cuts, burns, and abrasion common in industrial environments. A heavy-duty metal spring strain relief at the handle and the rear plug ensures the cable remains protected from kinking, extending the service life of the equipment.
Maintenance is straightforward with the Tweco Classic No. 4. It utilizes the widely available Tweco 14 Series contact tips, 24 Series nozzles, and 54 Series gas diffusers. This compatibility ensures that consumables are easy to source and cost-effective to stock. The gun's design allows for field repairs, meaning liners, trigger switches, and conductor tubes can be replaced on-site, minimizing downtime. Whether you are outfitting a production line or a job shop, the Tweco Classic No. 4 delivers the consistency and power required for professional results.
