258293 - Miller Water-Cooled Head Tube Assembly 45-Degree 6-Inch Heavy-Duty

Genuine Miller Replacement Head Tube for Industrial MIG Systems

The Miller 258293 Head Tube Assembly is a critical component for maintaining the performance of your high-output water-cooled MIG welding systems. Designed specifically for Miller's heavy-duty application requirements, this head tube (often referred to as a gooseneck or swan neck) serves as the conductive path and structural extension of the welding gun. It is engineered to fit Miller XR-Aluma-Pro and compatible Push-Pull (AP/PP) water-cooled gun assemblies, ensuring a perfect seal for coolant flow and shielding gas coverage.

In industrial fabrication environments, equipment downtime can be costly. The Miller 258293 is built to "Heavy-Duty" specifications, meaning it is constructed with robust materials capable of withstanding the intense heat and physical wear associated with continuous welding operations. The water-cooled design is essential for high-amperage welding, effectively dissipating heat to prevent overheating of the contact tip and nozzle, which in turn extends the life of your consumables and improves arc stability.

This assembly features a standard 45-degree bend, which is the most versatile angle for general fabrication, allowing welders to access joints comfortably without straining their wrists. The 6-inch length provides adequate reach for most bench and positioner work. When your existing head tube becomes clogged, bent, or leaks coolant, replacing it with this genuine Miller OEM part restores your equipment to factory specifications. At Josef Gas, we prioritize stocking authentic replacement parts to keep your production line moving efficiently.

Whether you are welding aluminum in a shipyard or fabricating heavy steel structures, the integrity of your torch neck is paramount. This kit comes as a complete assembly ready for installation, minimizing service time. Trust in Miller's engineering to deliver consistent wire feeding and current transfer through this durable head tube assembly.
