Miller XMT 350 FieldPro Welder

What should I do if the Miller XMT 350 FieldPro has no output?

Check that all power connections are secure, verify the power source is turned on and the circuit breaker is not tripped, and ensure the work lead is properly connected to a grounded surface.

What is the Miller XMT 350 FieldPro and what welding processes does it support?

The Miller XMT 350 FieldPro is a multiprocess welding power source with ArcReach technology that allows remote voltage control without a control cord. It supports MIG (GMAW), Pulsed MIG (GMAW-P), RMD®, Stick (SMAW), TIG (GTAW), Flux-cored (FCAW), and Air carbon arc cutting and gouging (CAC-A).

What are the specifications and power requirements for the Miller XMT 350 FieldPro?

The XMT 350 FieldPro has an output range of 10–38 V and 15–425 A, with a maximum open-circuit voltage of 75 VDC. It requires Auto-Line™ input power of 208–575 V with 3- or 1-phase capability, weighs 93 lb, and has dimensions of 17.25 in. (H) × 14.5 in. (W) × 27.125 in. (D).

What is the duty cycle of the Miller XMT 350 FieldPro?

The duty cycle varies with amperage settings: at 300 A the duty cycle is 60%, and at 450 A it is 100%.

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.

What is ArcReach technology and how does it work?

ArcReach technology allows remote voltage control at the wire feeder or remote without needing a control cord, enabling operators to adjust welding parameters directly at the weld joint. This maximizes arc-on time, improves safety, and enhances jobsite productivity.
