Description

The Miller XMT 400 multiprocess power source delivers 400A at 60% duty cycle and includes ArcReach, Auto-Line, and dedicated weld processes (e.g. gouging, flux core, self-shielded, etc.) This machines combines power and portability, weighing in at just 75 pounds. 

With ArcReach, you can operate further away from the power source, reducing downtime and costs while providing full remote control capabilities right at the weld site. Note that to fully utilize these features, the XMT 400 ArcReach must be paired with a Miller ArcReach feeder or remote.

Versatile in function, the XMT 400 ArcReach supports MIG, pulsed-MIG, Stick, and DC TIG welding. It can operate on both three-phase and single-phase input power, featuring Miller's Auto-Line™ technology, which allows for use with 208 to 575 volts, single or three-phase input without manual adjustments. The Cable Length Compensation (CLC™) automatically adjusts the welder's output to counteract voltage drops over long cable runs, ensuring consistent performance.

ArcReach Technology

ArcReach capabilities increase jobsite productivity and efficiency by eliminating the time spent tracing weld cables hundreds of feet back to the power source because weld operators can make voltage adjustments at the ArcReach wire feeder or remote.

Cable Length Compensation

Cable Length Compensation (CLC™) ensures that the voltage a weld operator sets is the voltage they get by automatically adjusting voltage based on weld cable length, even hundreds of feet away from the power source.

Improved Jobsite Safety

The chances of slip, trip and fall injuries are decreased because ArcReach technology allows weld operators to make parameter changes at the wire feeder or remote instead of having to travel through multistory and cluttered jobsites back to the power source.

Control Panel Lock Out

Inadvertent parameter changes by other jobsite workers can be avoided because connecting an ArcReach accessory to the power source automatically locks out the power source’s panel controls.

Auto-Process Select

Decrease the chance of an incorrect weld process being used because Auto-Process Select automatically sets the power source to the correct weld process based on the polarity applied to the weld accessory.

Auto-Line Technology

Work in more places with Auto-Line technology which automatically calibrates the power source to operate properly when connected to any primary input voltage ranging from 208-575 volts, single- or three-phase, 50 or 60 Hz — with no manual linking required.

ArcReach Heater Compatibility 

Adjust While Welding

Weld operators have more control and can Adjust While Welding (AWW™) to make fast, easy weld parameter changes at the wire feeder or remote — even while the arc is on. Only Miller offers this advanced solution.
