How do I set up and connect the Miller XMT 350 FieldPro?

Connect the power source to a compatible 3- or 1-phase power supply within 208–575 V, verify all connections are secure and meet local electrical codes, connect the ArcReach accessory which will be automatically recognized, attach the work lead to a clean unpainted metal surface for proper grounding, and connect the shielding gas supply ensuring all connections are leak-free.
