XMT ® MPa Series See Literature No. DC/18.84
The simple, powerful XMT MPa models can handle almost any portable welding application.
Add a 70 Series MPa Plus or XR-AlumaFeed feeder for a synergic system that simplifies
Pulsed MIG welding applications.
XMT MPa Series takes the features of the XMT 350
and 450 CC/CV multiprocess inverters and adds
built-in Pulsed MIG capabilities.
• Easy-to-use Pulsed MIG, including programs for
exotic alloys
Eliminates need for separate pulse control pendant or
•
•
other pulse controls
Pulsed MIG works with voltage sensing, remote control
and benchtop wire feeders
MPa — MIG; Pulsed; advanced Arc Control. Easy-to-use
advanced arc control enables an improved Pulsed MIG
welding arc.
Built-in Pulsed MIG programs contain optimal
parameters for steel, metal-cored, stainless, aluminum,
nickel, silicon bronze and copper nickel wire. Just dial
in wire and gas type. As easy to use as traditional MIG,
the MPa’s intuitive programming virtually eliminates the
Pulsed MIG learning curve for experienced MIG operators.
SharpArc® controls the arc in Pulsed MIG mode and
gives total control over the arc cone shape, puddle
fluidity and bead profile.

MULTIPROCESS
Synergic Pulsed MIG — Adding a 70 Series MPa Plus
feeder for steel or a XR-AlumaFeed feeder for aluminum
welding gives you the benefit of a Synergic Pulsed MIG
system. As you increase/decrease the wire feed speed,
the pulse parameters increase/decrease, matching the
right amount of power output to match the wire speed.

XMT 350 model allows for any input
voltage hookup (208–575 V) with no
manual linking. 450 model is 230/460 V manual link.
Dinse- or Tweco ®-style weld disconnects provide
high-quality weld cable connections (two connectors
supplied with each unit). 450 model has studs.
Optional 115 VAC auxiliary power provides 10 amps of
circuit-breaker-protected power for water circulators, etc.
