Miller Electric Mfg. LLC has introduced the new XMT 350 FieldPro system with Polarity Reversing. The system’s technology eliminates the need to manually swap leads between welding processes — saving time and money and improving safety on the jobsite. With the push of a button on the interface, Quick-Select technology automatically selects the correct polarity, lead outputs and weld parameters. This prevents operators from inadvertently welding in the wrong polarity, reducing the risk of weld rework that results from incorrect cable connection. Quick process changeover also eliminates the setup time spent switching cables and gas hoses. The system’s optimized stick and TIG arc performance is specifically designed for open root pipe welding — including process pipe and modular assembly applications — to help improve weld quality.
