10401937 - Tweco Classic #4 MIG Gun 400A 25ft Euro Connect

Heavy-Duty Industrial Performance with the Tweco Classic No. 4

The Tweco Classic No. 4 MIG Gun is a legend in the welding industry, known for its rugged construction and unwavering reliability in the most demanding environments. This specific configuration (SKU: 10401937) combines the proven performance of the Classic No. 4 platform with a versatile Euro-style back-end connection and an extended 25-foot cable assembly. Designed for professional welders who require a torch that can withstand high-amperage welding cycles, this gun is rated at 400 Amps at a 60% duty cycle using CO2 gas, making it ideal for structural steel, heavy equipment manufacturing, and general fabrication.

One of the standout features of this model is the 25-foot cable length. In large workshops or shipyards where moving the power source is difficult or impossible, the extra reach provided by this gun is invaluable. Despite the length, Tweco's high-quality cable construction ensures consistent wire feeding and stable arc characteristics. The cable utilizes high-grade copper stranding to minimize voltage drop and heat buildup, ensuring that the operator remains comfortable even during long welds.

The inclusion of a Euro connection expands the compatibility of this classic torch. Many modern inverters and European-designed welding machines utilize this standardized connection, allowing users to upgrade their existing equipment with the superior ergonomics and durability of a Tweco gun. The handle itself features the signature Tweco curved design, which balances the weight of the cable and reduces wrist strain, a critical factor for welder fatigue management.

Maintenance is straightforward with the Classic No. 4. It utilizes the widely available Tweco 14 Series contact tips, 24 Series gas nozzles, and 44 Series liners. The gun is completely field-repairable, meaning that if a component wears out or breaks, it can be replaced quickly without discarding the entire assembly. This focus on serviceability reduces long-term operating costs and keeps downtime to a minimum.
