XMT 350 VS specifications

The Miller Electric XMT 350 VS is a premier multi-process welding power source designed for versatility and efficiency in various welding applications. Renowned for its rugged construction and advanced technology, the XMT 350 VS offers exceptional performance for professionals in the welding industry.

One of the key features of the XMT 350 VS is its multi-process capability. It can handle MIG, TIG, stick, and even flux-cored welding, making it suitable for a wide range of projects, from thin sheet metal to heavy structural components. This multi-functionality allows welders to switch processes easily, streamlining their workflow and reducing downtime.

The XMT 350 VS is equipped with Miller's Auto-Set technology. This innovative feature automatically adjusts the welding parameters based on the material thickness and type of welding process selected. This not only simplifies the setup for the welder but also enhances the quality of the welds by ensuring optimal settings every time.

Another notable characteristic is its output range. The XMT 350 VS can deliver a maximum output of 350 amps, providing the power needed for demanding welding tasks. This makes it an ideal choice for both industrial applications and heavy-duty tasks in the field. Additionally, it operates on either 120V or 230V input, allowing for versatility in different job site environments.

The XMT 350 VS utilizes Miller's proprietary “Digitally Controlled” technology, which enhances the precision of the welding arc. This results in improved arc stability, refined bead appearance, and reduced spatter. The advanced design also contributes to energy efficiency, helping to lower operational costs in the long run.

Portability is another strong suit of the XMT 350 VS. Its lightweight and compact design make it easy to transport, an essential feature for welders who frequently move between job sites. The durable construction ensures that it can withstand tough conditions, providing a reliable performance wherever it's needed.

In summary, the Miller Electric XMT 350 VS is a versatile, powerful, and portable welding machine that offers advanced features such as Auto-Set technology, multi-process capabilities, and robust construction. Whether for industrial applications or field work, it meets the diverse needs of professional welders, making it a top choice in the market.
