Item Details

  • Miller® 400 A Water Cooled XR-Aluma-Pro™ Plus Gun with 25' cable features standard aluminum for wire tension adjustment and quick connectors. It contains isolated drive roll and replaceable full-length gun liner and is used in manufacturing/production facilities as well as in light and heavy fabrication.


  • The XR-Aluma-Pro air-cooled gun offers 300 amps—more amperage than the competition can handle
  • 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 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.)
