Miller's XMT 400 Multiprocess Welder is a multiprocess power source for professional welders seeking efficiency, control, and versatility. Compatible with Intellx wire feeders, it enables advanced processes that enhance performance across a wide range of welding applications.

The XMT 400 paired with Intellx Elite feeders enables:

  • Regulated Metal Deposition (RMD): Reduces welding current for improved puddle control, less spatter, and better fit-up
  • Versa-Pulse: Fast, precise welds with a tight arc, ideal for automation and thin materials
  • Accu-Pulse: Adaptive pulsed MIG process for smooth, consistent welds with minimal spatter
  • HD MIG: High-deposition MIG for faster, larger welds with lower heat input, suitable for structural steel and heavy manufacturing

Features:

  • Simplified weld parameter setup for faster starts
  • Familiar controls reduce training time
  • Compatible with 14-pin and volt-sensing feeders, plus Intellx Basic, Pro, and Elite
  • Arc control and LED indicators for real-time feedback
  • Easier serviceability reduces downtime
  • Increased performance for demanding applications
