OVERVIEW

Industrial Reliability Meets Advanced Pulse Technology

The Miller XMT 350 MPa is a premier choice for industrial fabrication, construction, and heavy manufacturing, offering a robust multiprocess platform that includes advanced Pulsed MIG capabilities. Designed to tackle the most demanding jobs, this power source combines Miller's legendary reliability with sophisticated arc control technologies. The unit features Auto-Line Power Management Technology, which allows for connection to any input voltage ranging from 208 to 575 VAC, single- or three-phase, without manual linking. This flexibility makes it an ideal solution for job sites with dirty or unreliable power, ensuring consistent performance regardless of the electrical infrastructure.

One of the standout features of the MPa model is its built-in pulse programs. These programs are specifically tuned for standard steels, high-strength steels, and aluminum, providing reduced heat-affected zones and faster travel speeds. For facilities looking to improve productivity and weld quality, the XMT 350 MPa simplifies the process. When paired with Miller's 70 Series MPa wire feeders, the system offers Synergic Pulsed MIG control; as the operator adjusts wire feed speed, the pulse parameters automatically adjust to match, eliminating the need for complex fine-tuning.

Durability is at the core of the XMT design. The Wind Tunnel Technology™ prevents abrasive dust and particles from damaging internal components by directing airflow through a dedicated tunnel, while the Fan-On-Demand™ cooling system operates only when necessary. This reduces noise, energy consumption, and the intake of contaminants. The unit also includes a standard 115 VAC auxiliary power receptacle, providing 10 Amps of circuit-breaker-protected power for cooling systems or small tools, adding another layer of utility to this versatile machine.

This model (907366011) comes equipped with Dinse-style weld cable connectors for high-quality, secure connections and includes the auxiliary power feature. Whether used for structural steel, shipbuilding, or general fabrication, the XMT 350 MPa delivers the power, precision, and portability required by modern industry standards.

FAQ

The XMT 350 MPa includes all the features of the CC/CV model but adds built-in Pulsed MIG programs and SharpArc technology for advanced arc control. It also supports synergic pulsed MIG when paired with compatible MPa wire feeders.

No, the XMT 350 MPa (907366011) is a power source only. It requires a separate wire feeder, such as the Miller 70 Series MPa or S-74 MPa, for MIG welding operations.

Auto-Line Power Management Technology allows the machine to connect to any input voltage between 208V and 575V, single- or three-phase, without manual linking. It automatically adjusts to the available power.

The XMT 350 MPa is a DC machine, so it is not suitable for AC TIG welding of aluminum. However, it is excellent for DC TIG on steel and stainless steel, and it can weld aluminum using the Pulsed MIG process.

The 115 VAC, 10-Amp auxiliary power receptacle allows you to run accessories such as a Coolmate coolant system or small power tools directly from the welder without needing a separate extension cord.

This specific model (907366011) uses Dinse-style connectors (50mm) for the weld cables. Two Dinse connectors are typically supplied with the machine.

SharpArc is a control feature available in Pulsed MIG mode that adjusts the focus of the arc cone. It allows the welder to tailor the arc stiffness and bead profile to the specific application.

Yes, the XMT 350 MPa is designed for rugged environments. Its Wind Tunnel Technology protects internal components from dirt and dust, making it reliable for outdoor construction and field repair.
