XMT® 400 MIGRunner™ with Intellx™ Elite Wire Feeder #951000212

The XMT® 400 is the newest member of the XMT family—built for nonstop shop work and backed by Miller’s proven reliability. Compatible with any Intellx™ wire feeder, it scales from core MIG/Stick/TIG to advanced pulsed capabilities (Accu-Pulse® with Intellx Pro; full advanced suite with Intellx Elite). A familiar, user-friendly interface makes setup fast so operators can stay in the zone all day.

Highlights

  • ArcConnect™: Next-gen communication improves welds and allows point-of-use controls at the feeder.
  • Legacy meets pulse: Pulsed MIG with Intellx Pro/Elite offers 28% wider window and a forgiving arc.
  • Auto-Line™ Technology: Auto-calibrates to 208–575 V input, single- or three-phase, no manual linking.
  • Wind Tunnel Technology™: Airflow shields boards from dirt and debris, boosting long-term reliability.
  • Dedicated wire feeder options: Intellx Elite adds arc control. Intellx Pro adds Accu-Pulse®, EZ-Set, and memory.
  • Easy to use: EZ-Set simplifies setup by thickness, reducing complexity and training needs.
  • Fan-On-Demand™: Cooling runs only when needed, lowering noise, energy use, and contaminants.
  • Auto Remote Sense™: Unit auto-detects and enables remote control when connected.
  • AccuLock S Consumables: Reduce tip changes, cut troubleshooting, and boost productivity with AccuLock.
