MILLER XMT 350 PULSE MIG
Miller XMT 350 MPa — Professional Multi-Process Welder
The Miller XMT 350 MPa is a heavy-duty, multi-process inverter welder designed for professional tradespeople and industrial operators who demand versatility, precision and reliability on every job. Whether you're working on a fabrication floor, a remote job site or a shipbuilding facility, the XMT 350 MPa delivers consistent, high-quality results across the widest range of welding processes and base materials.
Welding Processes Supported
The XMT 350 MPa supports six core welding processes in a single machine: MIG (GMAW), Pulsed MIG, TIG (GTAW), Stick (SMAW), Flux-Cored (FCAW), and Air Carbon Arc Cutting and Gouging. This all-in-one capability eliminates the need for multiple machines, reducing capital expenditure and floor space without compromising performance.
Built-In Pulsed MIG Programs with Synergic Capability
When paired with the Miller S-74 MPa wire feeder, the XMT 350 MPa unlocks built-in Pulsed MIG programs with full synergic control — automatically adjusting parameters for optimal arc performance. This allows precise welding across a broad range of metals including mild steel, stainless steel, aluminium, nickel, copper, silicon bronze and titanium, making it one of the most material-versatile welders in its class.
Auto-Line™ Technology for Job-Site Confidence
Miller's exclusive Auto-Line™ technology allows the XMT 350 MPa to accept any input voltage from a single-phase or three-phase supply and maintain consistent welding output even when input power fluctuates by up to ±10%. This makes it ideal for generator-powered job sites, remote locations, and applications where power quality cannot be guaranteed.
Insight Core™ Compatible for Data-Driven Productivity
The XMT 350 MPa is compatible with Miller's Insight Core™ platform, giving supervisors and operators access to real-time welding data, arc-on time tracking, and quality metrics. This transforms raw welding data into actionable insights to improve productivity, reduce rework and manage costs across your operation.
