Miller® XMT® 400 MIGRunner™ with Intellx™ Pro Wire Feeder 951000212
The Miller® XMT® 400 MIGRunner™ with Intellx™ Pro Wire Feeder is a complete 400 amp MIG and pulsed-MIG welding system. The XMT 400 amp multi-process welder is capable of MIG, Stick and DC TIG welding. It operates on both three-phase and single-phase input power and features Miller's Auto-Line,™ which means you can use 208 volt to 575 volt, single or three-phase input power without manual linking. The included Intellx Pro wire feeder comes complete with digital meters, plus advanced features like EZ-Set MIG, EZ-Set Accu-Pulse™, pre-programmed parameters for steel MIG welding plus two open memory slots to store your custom welding procedures. Dual-wire model allows two different wire types to be available on one feeder, avoiding downtime from changing spools and drive rolls.
The XMT 400 comes standard with both legacy 14-pin and new ArcConnect™ wire feeder/remote receptacles. ArcConnect provides high speed communication between the Intellx wire feeder and XMT 400 to improve machine response and performance. ArcConnect also allows for full remote control of output amperage, voltage and weld process control, right at the Intellx wire feeder.
The XMT 400 is easy to move around the shop or jobsite. Its rugged case design ensures it will stand up to the punishment of extreme work environments. The XMT 400 can carbon arc gouge with carbons up to 5/16" diameter. It also features built-in Lift-Arc™ TIG arc starting for smooth DC TIG arc starts without the use of high frequency.
The complete MIGRunner package includes XMT 400 welder, Intellx Pro wire feeder, Bernard™ BTB 400 amp MIG gun, running gear with dual cylinder rack, flowmeter/regulator and all interconnecting cables and gas hose.

Features
14-pin receptacle
Has the flexibility to be used with spool guns, legacy 14-pin feeders, and remote controls.
ArcConnect™
Is a next generation communication that utilizes high speed signals to improve weld performance and allow point-of-use controls to be located at the feeder.
Superior MIG welding arc
Lower spatter than traditional MIG welders
Better arc performance with silicon bronze and coated materials
Accu-Pulse®
The most popular process for majority of industrial welding applications
Most adaptive arc on 16 gauge (1.6 mm) and thicker
Designed for all weld positions
Shop mobility
Is made easy with the smallest and lightest machine in its amperage class.
True multiprocess system
Provides conventional stick, TIG, FCAW, and MIG welding as well as the advanced technologies of RMD and pulse.
Auto-Line™
Provides state-of-the-art flexibility by automatically connecting to 208-575 VAC, single- or three- phase power without removing the covers to re-link the power source. No longer is there a concern if you have the correct machine for the shop or the job site.
Wind Tunnel Technology™
Internal air flow that protects electrical components and PC boards from dirt, dust and debris… greatly improving reliability.
Fan-On-Demand™
Cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.
Lightweight aerospace-grade aluminum case
Offers protection with the benefit of reduced weight.
Universal connector system
Quickly and easily allows the machine to be configured to either Tweco®, Dinse®, or Cam-Lok-style receptacles. (Welder ships with Dinse®-style receptacles installed).
More control for weld operators
Quick, easy adjustments at the wire feeder/remote.
Adjust While Welding (AWW™)
Change weld parameters while the arc is on.
Process selector switch
Reduces the number of control setup combinations without reducing any features.
Large, dual digital meters
Are easy to view and are presettable to ease setting weld output.
Auto Remote Sense™
Enables unit to automatically use remote control if connected to remote control receptacle.
Adaptive Hot Start™
Helps promote a fast positive arc ignition helping minimize defects.
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™ TIG
Provides arc starting that minimizes contamination of the electrode and without the use of high-frequency.
OPTIONAL gas solenoid for TIG welding.
