10401602 - Tweco Classic 4 MIG Gun, 400A, 12ft, Euro Connector

The Legend Continues: Tweco Classic No. 4 with Euro Connection

For decades, the Tweco Classic Series has defined the standard for manual air-cooled MIG guns in the welding industry. The Tweco Classic No. 4 MIG Gun (SKU: 10401602) carries this legacy forward, offering professional welders the robust performance and reliability they have come to trust, now configured with a Euro-Kwik connection. This 400-amp powerhouse is designed to tackle the toughest welding jobs, from structural steel fabrication to heavy equipment repair, ensuring you have the power and consistency needed for high-quality welds.

Unmatched Durability and Comfort

The Classic No. 4 is built around the welder's needs. It features the iconic paddle-style handle that fits naturally in the hand, reducing grip fatigue during long welding shifts. The handle is constructed from high-impact materials that resist cracking and damage from drops or rough handling, a common occurrence in industrial environments. The 12-foot cable assembly is engineered with heavy-duty copper stranding and a durable outer jacket that resists cuts, burns, and abrasion, ensuring a long service life even on the most demanding shop floors.

Versatile Euro-Kwik Compatibility

One of the standout features of this specific model is its Euro-Kwik back-end connection. While many traditional Tweco guns use the standard Tweco connection, this unit is ready out-of-the-box for welding machines equipped with European-style receptacles. This makes it an excellent replacement or upgrade for a wide variety of power sources, including many ESAB, Miller, and Lincoln machines that utilize the Euro standard. The secure connection ensures optimal current transfer and gas flow, minimizing resistance and preventing gas leaks.

Easy Maintenance and Consumables

Maintenance is a breeze with the Tweco Classic No. 4. It utilizes the widely available 14 Series contact tips, 24 Series gas nozzles, and 54 Series gas diffusers. These consumables are stocked in almost every welding supply shop, meaning you will never be left waiting for parts. The gun's modular design allows for easy liner replacement and field repairs, keeping your downtime to an absolute minimum. Whether you are running solid wire or flux-cored wire, the Classic No. 4 delivers consistent wire feeding and arc stability.

Invest in the tool that built the industry. The Tweco Classic No. 4 with Euro connection combines traditional toughness with modern compatibility, making it the smart choice for serious fabricators.
