Miller Launches the New XMT® 400 Multiprocess Welder at FABTECH

APPLETON, Wis. (September 2, 2025) — Miller Electric Mfg. LLC, a leading worldwide manufacturer of Miller® brand arc welding equipment, announces the debut of the XMT 400 multiprocess welder — the latest evolution in the trusted XMT family. Officially unveiling at FABTECH, the XMT 400 is built for today’s multitasking professionals who want to tackle everything that comes their way — without sacrificing the familiarity and reliability they count on.

The next-generation XMT 400 is designed to enhance your operation and unlock new levels of efficiency through its compatibility with Intellx™ wire feeders. While all Intellx feeders offer improved control, consistency, and performance – including pulse capabilities on the Intellx PRO – the complete range of advanced processes are exclusively enabled when the XMT 400 is paired with the Intellx Elite, including:

• Regulated Metal Deposition (RMD®): Reduces welding current for better puddle control, less spatter and improved fit-up.
• Versa-Pulse™: Enables fast, precise welds with a tight arc — great for automation and thin materials.
• Accu-Pulse®: Adaptive pulsed MIG process that delivers smooth, consistent welds with minimal spatter — suitable for a wide range of applications and skill levels.
• HD MIG: High-deposition MIG process produces faster, larger welds with lower heat input — ideal for structural steel and heavy manufacturing. 
   

This powerful duo also unlocks a wide range of additional benefits, such as the ability to set locks and limits for repeatable parameters and results across shifts and operator skill levels. Other exclusive benefits include:

• EZ-Set technology: Simplifies weld parameter setup for faster, more confident starts.
• Intuitive interface: Familiar controls reduce training time and help operators get right to work.
• Scalability: Compatible with your existing 14-pin and volt-sensing feeders, in addition to the Intellx Basic, Pro and Elite feeders, find the perfect solution for your operation.
• Arc control and LED indicators: Provide real-time feedback and enhanced visibility on the power source.
• Lower maintenance costs: Designed for easier serviceability with reduced maintenance costs.  
• More gouge power: Delivers increased performance for demanding applications.
