Item Details

  • Miller® XR-Aluma Pro™ A Gun - 25ft.


  • The XR-Aluma Pro™ air-cooled gun offers a full 300 amps of output, more amperage than the competition can handle
  • Improved strain relief at both the front end and back end of the torch leads to extend cable life and increase comfort.
  • Aluminum-series-specific tension setting ensures smooth wire feeding performance with 4000 or 5000 series aluminum wires.
  • At 900 inches per minute, this gun will feed wire faster than any of its predecessors. 3-3/4 turn potentiometer provides better resolution when selecting the right wire speed for the job. The recessed WFS (wire feed speed) control offers durability yet is easy to use while wearing welding gloves.
  • The easy-to-rotate, self-seating head tube allows for better access into tight spots, preventing leaks and providing excellent current transfer.
  • The XR-Aluma Pro trigger has a wiping action to keep contact points clean for a more reliable electrical connection.
  • Trigger hold reduces fatigue by allowing operator to weld without holding trigger. (Feature available when paired with XR-Control.)
  • Isolated, common, knurled drive roll helps reduce wear, reducing downtime and cost. Replaceable feed cable liner is designed to provide consistent arc performance. It also reduces parts cost and service time by allowing a simple means of removing and replacing liner and not the complete feed cable.
  • Serviceability. This gun features a full-length Velcro®-seamed leather jacket with integrated strain reliefs for easy cable maintenance and protection. The gun also features quick connectors between the control cable and electrical components (trigger, motor, potentiometer).
  • Head tubes are standard Roughneck®, FasTip™ and are Bernard® Centerfire™ compatible. Guns are warranted for 1 year, parts and labor.
  • Easy access to drive assembly and removable head tube reduces service time. Pressure release lever allows drive rolls to be held open for wire changeover
