230678 - Miller XR-Aluma Pro FasTip Gas Diffuser 1/4 Recess

Miller XR-Aluma Pro FasTip Diffuser - 1/4" Recess

Maximize the performance of your aluminum welding operations with the Miller 230678 FasTip Diffuser. This genuine Miller component is an essential part of the front-end consumable system for XR-Aluma Pro push-pull guns. Aluminum welding requires precision equipment to handle the soft wire and high heat inputs; this diffuser is engineered to facilitate smooth wire feeding and superior arc transfer by securely holding the contact tip in place.

The 230678 model provides a 1/4-inch tip recess when paired with the appropriate nozzle. This recess is ideal for many standard welding joints, offering a balance between gas coverage and visibility. By recessing the tip, the diffuser helps protect the contact tip from direct arc exposure and spatter accumulation, which can otherwise lead to burn-backs or erratic arcs. The FasTip interface allows for quick and secure tip changes, a feature that significantly improves productivity on the shop floor by reducing setup time.

Constructed from high-conductivity materials, this diffuser ensures that welding current is transferred efficiently from the gun neck to the wire. It also plays a crucial role in the thermal management of the front end, helping to dissipate heat away from the contact tip. For fabricators relying on the XR-Aluma Pro for consistent aluminum wire feeding, using the correct diffuser is non-negotiable. Ensure your equipment remains within factory specifications and produces X-ray quality welds by choosing the Miller 230678 replacement diffuser.
