Item Details

  • Miller® XMT® 450 CC/CV Welder Power Source with auxiliary power supply allows for any input voltage hook-up with no manual linking, providing convenience in any job setting. Welder operates at voltage rating of 230 - 460 VAC with frequency of 60 Hz. Power source has large and dual digital meters that offers ease of view and presettable to setting welded output for convenience. It is ideal for use in construction, industrial and fabrication applications.


  • Wind Tunnel Technology™ Internal air flow that protects electrical components and PC boards from dirt, dust, debris... greatly improving reliability
  • Welder friendly control panel
  • Large, dual digital meters are easy to view and presettable to ease setting weld output
  • Process selector switch reduces the number of control setup combinations without reducing any features
  • Ultra-tough, polycarbonate-blended cover for control panel protects front controls from damage
  • XMT 450 MPa Models
  • Built in pulse programs are added to our XMT 350 bringing benefits to both standard and high strength steels: reduced heat affected zone, weld in all positions, great for thick to thin metal, good gap filling ability and faster travel speeds and deposition
  • Advanced Features for the Professional Welder
  • Designed for the professional welder, the XMT delivers unbeatable arc performance for DC Stick, Wire and TIG processes: Adaptive Hot Start™ makes starting Stick electrodes easy without creating and inclusion
  • Infinite arc control available in the Stick and Wire modes for easier fine tuning of tough-to-weld materials and out-of-position applications
  • Lift-Arc™ start provides arc starting that minimizes contamination of the electrode and without the use of high frequency
  • Fan-On-Demand™
  • Fan-On-Demand operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine Low OCV Stick
  • This simplified version is ideal for Construction or Fabrication applications in which the 14 pin receptacle is not needed for remote control or 14 pin feeders. This is designed for DC Stick, TIG and Wire with a Voltage Sensing Wire Feeder
