XMT® 400 MIGRunner™ with Intellx™ Basic Wire Feeder #951971

The XMT® 400 is the newest member of the XMT family—built for nonstop shop work and backed by Miller’s proven reliability. Compatible with any Intellx™ wire feeder, it scales from core MIG/Stick/TIG to advanced pulsed capabilities (Accu-Pulse® with Intellx Pro; full advanced suite with Intellx Elite). A familiar, user-friendly interface makes setup fast so operators can stay in the zone all day.
