112704 - Miller 112704 Contact Tip Adapter for Spoolmatic and XR Guns

Genuine Miller 112704 Contact Tube Adapter

The Miller 112704 Adapter, Contact Tube is a critical component designed for specific Miller MIG welding guns, particularly those used in aluminum fabrication and heavy-duty industrial applications. This genuine OEM part serves as the interface between the gun's head tube and the contact tip (or tube), ensuring that the welding current is effectively transferred to the wire. Manufactured from high-quality brass, this adapter is engineered to withstand the thermal stresses of welding while providing low electrical resistance.

This specific adapter is compatible with a range of Miller's push-pull and spool guns, including the renowned Spoolmatic 1, Spoolmatic 2, and Spoolmatic 3 models. It also fits the XR-15 and XR-30 series guns, which are staples in industries requiring long-distance wire feeding for aluminum. Additionally, it serves as a replacement part for the legacy GA-series guns, such as the GA-20C, GA-21C, GA-40C, and GA-50C. Ensuring your equipment is fitted with the correct adapter is vital for preventing issues like micro-arcing inside the gun, which can lead to premature failure of the head tube or contact tip.

At Josef Gas, we understand that maintaining the integrity of your welding torch is essential for productivity. A worn adapter can cause poor arc starts, unstable arcs, and irregular wire feeding. By replacing your worn contact tube adapter with this genuine Miller 112704 unit, you restore the electrical efficiency of your MIG gun. The precision threading ensures a tight mechanical fit, preventing gas leaks and ensuring that the shielding gas is properly directed around the weld pool. Whether you are repairing an older Spoolmatic gun or maintaining a fleet of XR systems, this adapter is the exact specification required for optimal performance.

Installation is straightforward, requiring standard tools to unthread the old unit and seat the new one. Regular inspection of this component during contact tip changes is recommended to catch signs of wear, such as thread damage or erosion from heat, before they impact weld quality.
