When your shop needs a welder that can do it all and do it well, the Miller XMT 350 CC/CV MIGRunner with S-74D feeder is the answer. This all-in-one package takes the guesswork out of configuring a heavy-duty welding station. By pairing the industry-standard XMT 350 inverter with the advanced S-74D digital wire feeder and mounting them on a heavy-duty cart, Miller delivers a mobile welding powerhouse ready to tackle everything from structural steel to manufacturing fabrication.
The XMT 350 is famous for its smooth, stable arc. With Infinite Arc Control, you can fine-tune the arc characteristics in Stick and MIG modes to suit your specific application and personal preference. For TIG welders, the Lift-Arc feature allows for arc starting without the use of high frequency, minimizing the risk of interference with sensitive electronics nearby. The Adaptive Hot Start for Stick welding automatically increases output amperage at the start of a weld if necessary, preventing electrode sticking and ensuring a clean start every time.
Quality control is easier than ever with the S-74D wire feeder. The digital display provides clear, accurate readings of your voltage and wire speed, allowing you to dial in your settings according to the Welding Procedure Specification (WPS). This eliminates the "guess and check" method often associated with analog dials, saving you time and materials. The feeder is designed to deliver smooth, consistent wire feeding, which is critical for producing high-quality welds and reducing spatter.
This package is built to save you money over the long haul. The high power efficiency of the XMT 350 inverter reduces utility costs compared to older transformer-based machines. The reliability of the Auto-Line technology means you won't experience downtime due to input power fluctuations. Plus, the MIGRunner cart keeps everything self-contained, reducing setup time when moving from one part of the shop to another. The package comes complete with a Bernard MIG gun, known for its comfort and durability, ensuring your welders can work longer with less fatigue.
The 907464 package is fully loaded. You get the XMT 350 CC/CV power source, the S-74D digital feeder, a factory-installed running gear/cylinder rack, a 4/0 MIG kit with DINSE connectors, and a premium regulator. It is the perfect upgrade for shops looking to modernize their equipment with reliable, multi-process technology.
