What's Included

Heavy-Duty Low-Speed DEUTZ TD2.9 L4 T4F Industrial Diesel Engine
The cleanest, greenest diesel power available. DEUTZ T4F models utilize diesel oxidation catalyst (DOC) technology to keep the air clean with NO exhaust after-treatment maintenance.
Multi-Arc Welding
One dependable engine - two independent arcs with up to 400 amps each (or 800 amps for a single operator). Plug in additional inverter welders for a true multi-operator (3+ arc) work platform!
Increased Efficiency
More arcs and better fuel economy equal increased profits for your business. Estimated savings are 34-percent with a dual-operator unit versus two single-operator units.
Air Compressor - Ingersoll Rand
Ultra-reliable industrial rotary screw air compressor. 30,000-hour life expectancy. Independent on/off control for applications not requiring compressed air — allows for greater fuel savings and longer compressor service intervals.
Industrial USB Port
Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.
ArcReach® Technology
Exclusive ArcReach technology uses existing weld cables to communicate process adjustment commands back to the welder generator. With an ArcReach system, amperage & voltage are conveniently located at the operator's fingertips - not back at the power source.
ArcReach® Accessories for Every Application
Whether the weld specification calls for Stick, TIG, MIG, Flux-Cored or an advanced wire process, Miller has an ArcReach accessory that can get the job done.
Increased Productivity & Safety
More arc-on time, and reduced exposure to slip, trip, and fall hazards can be realized using ArcReach because less time is spent going back to the welding power supply to set process and arc amperage or voltage.
Electronic Engine Display
Electronic engine display simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, air pressure and engine RPMs. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
Other Standard Features
Output contactor control, automatic idle, thermal overload protection, digital meters with SunVision™ and 120-volt engine block heater.

Accessories

ArcReach Stick-TIG Remote
ArcReach® Stick/TIG Remote

Portable and lightweight, the ArcReach stick/TIG remote paired with a Dimension, XMT, or compatible engine-driven ArcReach power source allows you to change weld setting at your work area, saving a trip to the power supply. No extra control cable to purchase, maintain, string or unstring—saving time and money.
FieldPro Smart Feeder
FieldPro™ Smart Feeder

FieldPro Smart Feeder system delivers excellent RMD® and Pulse, MIG and Flux-Cored welding up to 200 feet away from the power source with no control cables. This system provides full remote control capabilities, including weld process selection, material type and wire diameter, gas type, wire feed speed and voltage from the feeder at the weld joint. The PipeWorx 350 FieldPro Power Source automatically shifts all controls to the Smart Feeder, eliminating confusion, hassle with cords and controls while improving safety.
