229670 - Miller 229670 FasTip Gas Diffuser for XR-Aluma-Pro Guns

Genuine Miller Replacement for XR-Aluma-Pro Guns

Keep your Miller XR-Aluma-Pro push-pull gun operating at peak performance with the Miller 229670 FasTip Gas Diffuser. Designed specifically for the unique demands of aluminum wire feeding, this OEM component is essential for maintaining a smooth and reliable arc. Aluminum welding presents distinct challenges compared to steel; the wire is softer and more difficult to push, making the alignment of internal components critical. This diffuser acts as the bridge between your gun's liner and the contact tip, ensuring that the wire transitions smoothly without snagging or buckling.

The 229670 diffuser is engineered with a 1/8-inch tip recess, a configuration that protects the contact tip from excessive spatter and radiant heat while ensuring optimal gas coverage over the weld zone. This recess is particularly effective for heavy-duty applications where high amperage is required. The diffuser works in tandem with Miller's FasTip contact tips, utilizing a unique locking mechanism that centers the tip with the liner lock. This alignment minimizes wire drag and drastically reduces the occurrence of burn-backs, a common frustration that interrupts production and damages equipment.

Durability is a key feature of this component. Constructed from high-quality conductive alloys, the diffuser withstands the thermal cycling and electrical loads inherent in industrial MIG welding. It effectively transfers current to the contact tip while managing heat dissipation. The design also facilitates efficient gas distribution, promoting a laminar flow of shielding gas that protects the molten aluminum from atmospheric contamination and porosity. Whether you are welding thin gauge aluminum sheet or heavy plate, consistent gas coverage is non-negotiable.

This package contains one genuine Miller diffuser. It is compatible exclusively with the XR-Aluma-Pro series and is not intended for use with other Miller guns or standard MIG torches. By using genuine Miller parts, you ensure that your equipment meets factory specifications for safety and performance. Don't let poor consumable quality compromise your welds. Upgrade your front-end consumables to the 229670 FasTip diffuser and experience the difference in feedability and arc stability that comes with precision engineering.
