10441132 - Tweco Fusion Pro 9W 500A Water-Cooled MIG Gun, 12ft, Miller Backend

Heavy-Duty Industrial Performance with Tweco Fusion Pro

The Tweco© FUSION PRO™ 9W Water Cooled MIG Gun (Part Number FPW9512M116) is engineered for the most demanding industrial fabrication environments. Designed to handle high-amperage applications, this 500-amp rated gun utilizes an efficient water-cooling system to maintain lower operating temperatures during extended weld cycles. This thermal management is critical for heavy manufacturing, shipyards, and structural steel fabrication where downtime for equipment cooling is not an option. The gun comes equipped with a 12-foot cable assembly, providing a robust balance between reach and wire feedability, ensuring consistent arc performance even with larger diameter wires like the pre-configured 1/16-inch setup.

At the core of this system is the Miller-style backend connection, making it a seamless drop-in replacement for fleets utilizing Miller wire feeders. This compatibility reduces inventory complexity and allows for immediate deployment on the shop floor. The Fusion Pro series is renowned for its durability; the cable assembly features a tough outer jacket resistant to cuts, abrasion, and hot surfaces, protecting the internal power cable and water lines from the harsh realities of the industrial workspace. The knuckle joint at the handle and the spring strain relief at the feeder end work together to prevent cable kinking and ensure smooth wire delivery.

Maintenance and consumable life are optimized through the Tweco Fusion consumable platform. The contact tips thread directly into the gas diffuser, creating a larger surface area for electrical transfer and heat dissipation. This design keeps the tip cooler, extending its life and reducing the frequency of changeovers. For industrial operations focused on productivity and weld quality, the Tweco Fusion Pro 9W delivers the reliability and power required to maintain high deposition rates shift after shift.
