Portability and excellent multiprocess
arc performance make the XMT family
the most popular in the industry.
With many models to choose from
the XMT family has the right solution
for your business.
Input power choices
(350 models) allows for any input voltage hookup
(230–575 V, three-phase) with no manual linking,
providing convenience in any job setting. Ideal solution for dirty or
unreliable input power.
Wind Tunnel Technology.™ Air flow that protects internal components, greatly
Fan-On-Demand™ cooling system operates only when needed, reducing noise,
energy use and amount of contaminants pulled through machine.
Standard hookup (450 models). 400 V only, three-phase.
Welder friendly control panel
Advanced features for the professional welder
Process selector switch reduces the number of control setup combinations
without reducing any features.
Adaptive Hot Start™ makes starting stick electrodes easy without
creating an inclusion.
Ultra-tough, polycarbonate-blended cover protects front controls from damage.
Infinite arc control available in the stick and wire modes for easier
fine tuning of tough-to-weld materials and out-of-position applications.
Large, dual digital meters are easy to view and presettable to ease setting
Lift-Arc™ provides arc starting that minimizes contamination of the
electrode and without the use of high frequency.
Output connector choices
Welding Intelligence™ system. XMT 14-pin
models are Insight Core capable to monitor
weld voltage, amperage, and arc-time and percentage.
Dinse-style weld disconnects (350 models) provide high-quality weld cable
connections. Machines come with two Dinse connectors.
Weld studs (450 models).
14-pin receptacle provides a quick, direct connection to Miller® wire feeders.
Capable of remote voltage control.
