The XTRWELD 135-425 is a Miller Style 135 Series contact tip designed for MIG welding with 0.062 inch aluminum wire. Contact tips are consumable components that guide the welding wire through the gun and transfer welding current at the point of contact. This tip is manufactured to OEM quality standards and is interchangeable with genuine Miller consumables of the same series. Each tip is marked with its part number or size for fast identification on the shop floor or in the field. Welding professionals and fabricators working with aluminum wire applications will find this tip sized and rated for the job.
This contact tip is intended for use with Miller XRa, XRMa, and Spoolmatic wire feeders and compatible MIG welding guns. It is suited for aluminum wire welding in fabrication shops, maintenance environments, and industrial production settings where consistent wire feed and reliable current transfer are required. The 0.062 inch bore corresponds to the aluminum wire diameter it is designed to accommodate.
Designed as an OEM-style replacement contact tip compatible with Miller XRa, XRMa, and Spoolmatic MIG gun systems using Miller Style 135 Series consumables.
Contact tip replacement is performed by qualified welding technicians as part of routine gun maintenance. Power down and disconnect the welding machine before removing or installing contact tips. Use the appropriate tip wrench to avoid cross-threading or damaging the gun head. Inspect the diffuser and nozzle for wear whenever the contact tip is replaced.
