258474 - Miller 180-Degree Air-Cooled Head Tube 4-Inch for XR-Pro and Spoolmatic Pro

Product Overview

The Miller 258474 is a genuine Head Tube Assembly designed specifically for the Miller Pro series of wire feeding guns. This component features a 180-degree (straight) geometry and a 4-inch length, making it an essential accessory for applications requiring direct, straight-on access to the weld joint. It is engineered for air-cooled operation, maintaining compatibility with standard air-cooled setups found in the Spoolmatic® Pro, XR™-Pistol-Pro, and XR™-Aluma-Pro systems.

Technical Specifications & Compatibility

This head tube is manufactured to precise Miller specifications to ensure seamless integration with compatible push-pull and spool guns. The assembly utilizes the Centerfire™ consumable system, which is renowned for its performance and ease of use. The connection mechanism is designed to be self-seating and requires no tools for installation, reducing downtime during changeovers. The head tube is fully rotatable, allowing the operator to orient the trigger and handle in the most comfortable position relative to the nozzle.

Compatible Miller Guns:

• Miller Spoolmatic® Pro Spoolgun
• Miller XR™-Pistol-Pro Air-Cooled Push-Pull Gun
• Miller XR™-Aluma-Pro Air-Cooled Push-Pull Gun

Operational Features

The 258474 assembly is built for durability in industrial environments. The 180-degree angle is particularly useful for automated or semi-automated setups where a straight torch angle is preferred, or for manual welding in tight spaces where a curved neck might obstruct the view or access. By utilizing Centerfire consumables, users benefit from better gas coverage and longer tip life, which is critical when welding sensitive materials like aluminum.

Note: This head tube is strictly compatible with the Miller Pro series spoolguns and air-cooled push-pull guns listed above. It is not designed for standard MIG guns or water-cooled variants unless specified by the manufacturer.
