246205 - Miller 246205 Water-Cooled Head Tube, 45 Degree, 6-Inch, Centerfire Series

Miller 246205 Water-Cooled Head Tube Assembly

The Miller 246205 is a premium replacement head tube assembly designed specifically for water-cooled push-pull MIG guns, including the XR-Aluma-Pro™ and XR-Pistol-Pro™ series. This component is critical for maintaining the structural integrity and performance of your welding gun during high-amperage aluminum welding applications. Engineered with precision, the head tube features a 45-degree bend and a standard 6-inch length, providing a balanced combination of reach and ergonomic comfort for the operator.

Optimized for Centerfire™ Consumables

This head tube assembly is configured to accept Miller's Centerfire™ consumable series. The Centerfire system is renowned in the industry for its threadless contact tips and spatter-shielded nozzles, which significantly improve arc starting and stability. By using this head tube, operators can ensure consistent gas coverage and wire feeding, which are essential when welding sensitive materials like aluminum. The integration with Centerfire parts also simplifies maintenance, allowing for faster changeovers and reduced downtime on the production floor.

High-Performance Cooling

Water cooling is essential for heavy-duty industrial fabrication, and the Miller 246205 delivers efficient thermal management. The internal cooling passages are designed to dissipate heat rapidly, allowing the gun to operate at 100% duty cycle at higher amperages compared to air-cooled alternatives. This prevents the front-end consumables from overheating, extends the life of the gun, and ensures operator comfort by keeping the handle and neck cool to the touch.

Durability and Compatibility

Manufactured to Miller's exacting standards, this head tube is built to withstand the rigors of daily industrial use. It serves as a direct replacement for damaged or worn necks on compatible water-cooled guns. Whether you are repairing a damaged unit or configuring a gun for a specific joint access requirement, the 246205 offers the reliability and fitment you expect from genuine Miller Electric components.
