W6015AI1CM - Bernard W-Series 600A Water-Cooled MIG Gun, 15ft, Miller Style

Heavy-Duty Bernard Water-Cooled Performance

The Bernard W-Series Water-Cooled MIG Gun (SKU: W6015AI1CM) is a powerhouse tool designed for the most demanding industrial welding environments. Engineered to handle high amperages and prolonged arc-on times, this 600-amp gun is the ideal solution for heavy fabrication, structural steel, and manufacturing sectors where heat management is critical. Unlike air-cooled models that can overheat during continuous high-current welding, the water-cooled design of the W-Series ensures that the front-end components remain at optimal operating temperatures, significantly extending the life of your consumables and reducing downtime.

This specific configuration comes with a 15-foot cable assembly, providing the necessary reach to maneuver around large workpieces without compromising wire feedability. It is pre-setup for 0.035-inch wire, making it ready for precision welding tasks right out of the box. The gun features a Miller-style direct plug connection, ensuring seamless integration with your existing Miller power sources. The robust construction of the cable and handle is built to withstand the rigors of the shop floor, resisting cuts, abrasion, and heat damage.

Operator comfort is paramount in high-production settings. Bernard has designed the handle to be ergonomic, reducing wrist strain and fatigue during long shifts. The efficient cooling system also keeps the handle cooler to the touch compared to high-amp air-cooled guns, improving operator safety and comfort. Whether you are welding thick plate or running long continuous beads, the Bernard 600A Water-Cooled MIG Gun delivers the reliability and performance required to maintain high productivity levels.

Key Benefits for Industrial Users

• Maximum Duty Cycle: Water cooling allows for 100% duty cycle at 600 amps (with CO2), enabling non-stop welding without equipment overheating.


• Consumable Longevity: Lower operating temperatures drastically reduce spatter adhesion and wear on contact tips and nozzles.


• Plug-and-Play Compatibility: Designed specifically with a Miller backend for quick and easy setup.
